Distinguished - BHPian ![]() ![]() | Re: My Barn Finds: Yamaha RD 125 & RD 200 Paris-Delhi-Mumbai @ €80 Nothing can happen before time and that stands true for the RD 125 rebuild. My second bike that I bought back in 2006 and it costed me peanuts especially when you look at RX’s that cost ten times it’s price today but, back then for me it costed me more than my monthly salary and was a big stretch and I was clearly not financially prepared to rebuild it. In 2010 I did try rebuilding it along with my RD 200 but due to unavoidable circumstances we couldn’t finish it then. Luckily for me that was a blessing as I clearly needed a new tank as the one that came on the bike was beyond repair. Also, I needed a set of new exhaust and both of them happened in quick successions last year as I found a decent complete set of exhaust from the US and my friend Moneet found a good tank in Paris itself. The RD 125 coffin tank especially is a very difficult to find piece and to find one in a good condition is even more difficult. But, as I have been saying in my previous posts my stars are aligned this time and my friend Moneet found a good tank and that too in Paris. He shared me the link back in September last year which I quickly approved and he called the owner who was not staying too far away from his house and he could pick it up personally. Unfortunately Moneet could not meet the owner until early December and the owner was kind enough to hold on to the tank till then. Now, the biggest dilemma was that of how to get the tank to India, neither Moneet or I were travelling to Paris/India. So, I asked him to ship it to India which I knew would cost a bomb. The quote he got online was around €148, which later we found out was the minimum amount and the actual post office charges could be much higher depending on the final package dimensions and weight. While I told Moneet to still go ahead with it he was not comfortable as the price of the tank is €80 and shipping it would cost double of that and then customs if any back in India. So, he was on a lookout for a cheaper alternative and during one such conversation a friend of his who was visiting India offered to hand carry it. Her sweet gesture just didn’t end there as she even couriered it to Mumbai from Delhi free of charge. Truly blessed to have such people around who would do such good deeds especially for a friends friend. 🙏🏻 Now, I can send the parts for paint and hopefully by next week we can have the RD 125 standing on its own feet… Some pictures… Christmas is long gone but the goodies still keep arriving. I am a complete madman to even attempt to do two full and some semi rebuild in one go and that too of rare bikes. ![]() Skinned down the outer tape packing ![]() First glimpse ![]() Peekaboo..

Distinguished - BHPian ![]() ![]() | Re: My Barn Finds: Yamaha RD 125 & RD 200 Time to paint With the arrival of the tank I have all the parts that need to go to Sumant at OCD Detail Studio for paint. This is the third bike of mine that he is going to paint and the details on this one is hopefully going to be less challenging compared to the previous two. The decals which are very minimal compared to the previous two are also less complex in nature to execute. The paint shade we have finalised is Ducati Red with pearls. The parts that are going to be painted red are the front and rear mudguard the tank and both the side panels. The front fork bottoms will be in Titanium/Gun metal as the other two and all other remaining parts will be painted black. We wanted the colour to really pop and no better red than the Ducati red and I also happen to have one in the garage with subtle hints of that same red shade for inspiration ![]() Just waiting on the Michelin tyres to arrive so that they can be fitted on the rims before they go for paint. They are expected next Wednesday so hopefully Thursday the parts can go for paint. On the RD 200, Tony has repaired the OE kick shaft and will now prepare the panel fins in aluminium. So, once those parts are ready they can go for painting as well. Some pictures…. The front end of the OE kick shaft for the RD 200 has been repaired and now the kick boss can fit properly. But need the OE spring as well so back to ordering from Yambits. Parts, Parts and more Parts… ![]() This is the OE kick shaft with spring and kick boss of the RD 125, which is off the same dimensions ![]() Next up is the plastic fins that fit on the side panels that are missing on the RD 200. Very difficult to source and next to impossible to get a new set. ![]() So, the next best option is to make one in aluminium ![]() The RD 125 parts are ready for paint. As I said earlier, the cosmetic details on this one are not complex to capture. Notice the side panels are plain with no fins. The second time they will be painted and I am glad that the Titanium grey shade never actually turned into a complete bike. ![]() OE Yamaha badging that will go on the engine covers after the paint but before the clear coat ![]() This one is a proper JDM motorcycle ![]() Part numbering ![]() Trying to capture the details of the coffin tank ![]() Preparing for paint ![]() Took off the rubber mount and fuel transfer tube ![]() Time for some in house paint colour inspiration ![]() Ducati red it is with pearls ![]() Golden wheels will turn all black though ![]() Never used 15 year old rubber.

Distinguished - BHPian ![]() ![]() | Re: My Barn Finds: Yamaha RD 125 & RD 200 Maiden highway run cut short It had been a few months since I took the RD 200 on the highway for a longer run and planned to do that this Sunday. In preparation for the Sunday ride washed and polished the RD 200 and RZ 350 on Saturday. This was the first wash and polish session done by me post the repaint and I will let the pictures speak the results for itself ![]() The plan was to ride upto Bombay Coffee House and this time my other two friends joined in too. However, once I reached Mahim the throttle cable started acting funny and just like the RZ the rpm wouldn’t drop when the throttle was cut off. I messaged my friends that I would head back but they then rather decided we have breakfast back in Mahim and head back together. I had to do multiple stops to adjust the throttle and once I got back on the highway the issue disappeared. Gladly I could ride back home and will get this inspected the next time I am at Tony’s. Some Pictures… First polish session after the wash ![]() Results under the sun ![]() Up close ![]() Top view ![]() Glad avoided the top decals. Would have made the tank too busy and make it look much more smaller ![]() What a colour contrast and the sight of those twin cylinders and exhaust.

And being 100cc smaller in displacement over the Indian RD’s still feels much more powerful.. ![]() Almost 30 kg weight difference in these two ![]() All that weight is on the frame and alloys which are much more chunkier on the DS ![]() A unique trivia is that both have speedos which are in MPH ![]() Two uniquely designed tanks ![]() Standing solo and will still attract a crowd ![]() Meeting the big daddy from the family lineup ![]() |

Distinguished - BHPian ![]() ![]() | Re: My Barn Finds: Yamaha RD 125 & RD 200 Precision Machining To maintain such a big collection of rare motorcycles is only possible when you have someone extremely knowledgeable to work and maintain them. And when that person is a perfectionist just like you it can create wonders like none other. I had mentioned that I was having difficulties in finding the fins that fit on the RD 200 panels. When I mentioned this to Tony and while we were brainstorming on what is the next best alternative he came up with the idea of making a set in aluminium. Machining parts for the RD 200 is something that is not new and we have made quite a few parts in house. But this needed precision on a next level because we wanted to recreate the same design as the original has and the measurements had to be perfect for to it have a perfect seat. Tony as usual worked out his magic and the finished product is nothing short of being magical to see and hold in your hands. Now, we will have to get the curvature correct before the piece can be sent for painting along with the RD 125 parts. Further, I went ahead and ordered a pair of kick springs to be used on the RD 200 and a kick from Ebay along with a tacho cable each for the RD 200 and RD 125 and and throttle cable for the RD 125. Since, I had no one coming down from UK immediately I couldn’t order from Yambits and had to rely on Ebay instead. Kick springs are arriving from Thailand and cables and the kick from Germany..Now, you can understand why maintaining a track of cost for such rebuilds never make sense as it can never give you a true picture of what sort of budget one has to expect other than knowing that it is going to turn out to be very very expensive… ![]() Some pictures… The original seat of the RD 125 and the half broken rear seat cowl. The seat lock mechanism is similar to the RXZ and now have to figure out if someone can make a same seat plate and repair the rear seat cowl as well ![]() The seat lock similar to the RXZ ![]() Fins for the RD 200 made out of aluminium and machined to perfection on a milling machine ![]() ![]() ![]() What a perfect seat ![]() Will have to bend them slightly for a perfect seat ![]() Planning to paint the fins in same titanium grey shade as the fork legs.

That is the benefit of working with aluminium soft yet strong and wont rust as well. Now, these two can go in for paint along with the other RD 125 parts… Some pictures… Look at those curves.

Distinguished - BHPian ![]() ![]() | Re: My Barn Finds: Yamaha RD 125 & RD 200 RD 125 Paint 2.0 The RD 125 parts have finally gone for paint and this is the second time they are getting painted after a gap of close to 15 years. Rusting is a major issue on older bikes and when a bike is left out in the open for decades at a stretch it just makes matters worst. The OE tank had already rusted beyond repair and had to source a used one to replace it and the next metal part which needed attention was the the rear mudguard which had developed many small rust holes which had to be filled up and smoothened out. Luckily all the old paint and base coat was completely scrapped out which made us aware of these issues to be fixed or else the paint would have eventually bubbled up again. Even though the process is taking longer I am glad we are doing a proper job and giving all the attention and care these rare bikes need and deserve. The engine of the RD 125 is ready with the coil plate being fitted and once its put on the chassis the final timing can be marked on the bike. Hopefully, by next week the RD 125 will be standing on its own feet once again and we can work towards firing it up for the first time in decades. Looking forward ![]() Some pictures…. Magnet fitted on the engine ![]() Coil plate. Converted to CDI and won’t be running on points any longer for ease of maintenance ![]() The carbs have been thoroughly cleaned ![]() Body parts being sent for paint ![]() The remaining batch of parts ![]() All the plastic parts will be cleaned thoroughly and a protective coat would be applied ![]() All the parts scraped down to the metal. The problematic rear mudguard stands out now showing its true condition ![]() A lot of pin rust holes have to be filled up ![]() The OE RZ front brake master cylinder cap. When you decide to rebuild a bike to OE spec you just have to go all out. Mine being a JDM spec has the Kanji lettering and I was not happy with the black finish from the powder coating process as it was too thick so getting it painted instead. ![]() Getting parts painted of three different bikes and don’t miss the side cover fins for the RD 200 in the right bottom corner. This last few months have been a marathon rebuild exercise. ![]() Up close ![]() Time to iron out imperfections to get a smooth finish ![]() ![]() And to fill up a few for a stronger base that will last a few more decades ![]() ![]() All set to get the striking Ducati Red shade ![]() Parts continue to arrive back at home ![]() The missing kick spring for the RD 200 came in from Thailand.

My RD 200 as per the RC records is supposed to be a 1982 model but in reality as per its engine number series is a 1972 model so it’s the oldest motorcycle in the collection. The RD 125 DX is a 1979 so the RC records have captured that correctly. It is a single owner motorcycle and was used sparingly and left to rust out in the open for many decades for some reason. I never got to meet the owner and only spoke with him on the phone as the deal was done with the mechanic with whom the bike was parked. Took a good six months of constant pestering for him to finally speak to the owner and agree to sell the bike to me.. And now after 19 years with me its heart will finally scream again and smoke a few four strokes on the streets of Bombay… ![]() Some pictures for nostalgia… A RD 125 DX with alloy wheels from factory somewhere in India ![]() The decals is what stands out and can be used to identify if the model is JDM spec or not ![]() Top view ![]() MRF tyres ![]() How mine looked when i brought it in 2006 ![]() The JDM spec decals ![]() No 125 decal on the side panel unlike the US and European models ![]() The painted panels in the exact same decal design but in paint ![]() This is how my bike would have looked when it rolled off the factory floor and came to Bombay in the late 70’s ![]() ![]() | |

Distinguished - BHPian ![]() ![]() | Re: My Barn Finds: Yamaha RD 125 & RD 200 Ignition after decades of Hibernation ![]() The wiring harness is done and all the lights have been fitted on the RD 125 minus the battery. A lot of correction and metal work was done on the carbs especially where the bowl fits and we were praying that it will hold well without any leaks and we would be able to start the bike. These parts are really old and ideally a new set of carbs would be required but getting one is a task of its own so we did our best to salvage the carbs. We wanted to get the bike started asap to ensure all the critical parts are taken care off and we can then focus our attention to the other cosmetic work that is pending. The carbs were fitted on the bike and filled with petrol to ensue no leaks and then the 2t oil tank was filled up and the pump was bled. Then the moment finally came when all systems were go to kick start the bike. A few initial kicks didn’t create and magic so we thought maybe the back pressure is not enough and inserted the baffles in both the mufflers. Post that the bike was still not firing up and the timing gun was taken out and we decided to advance the timing and that change is what made all the difference and the engine finally woke up from its very longgg slumber..For a screamer of a heart she has the sound track was very muted even compared to the RD 200 but no complaints and we will only hear and feel her real character when we put her in motion. Have waited for this day for 19 long years and the bike itself would have given up hope in believing that she would fire up once again.. But she was neglected for years at end even under my ownership but was never forgotten. My second bike and my first barn find was alive and kicking once again ![]() Now, though the engine has fired up the timing still needs to be advanced further but the coil plate is already at its most extreme position so that needs to come off to be machined out further. Also, a bracket has to be fabricated to mount the front mudguard and the meter bracket and also the seat base plate has to be fabricated from the original seat which has disintegrated over the years. So, the bike visually looks complete more than ever before but still a lot of small stuff needs to be done before the build is 100% complete and I can taken my maiden spin on the RD 125… Some pictures… An investment made 15 years ago finally gets the opportunity to go on the bike and not just remain an expensive trophy lying in my part collection.

All are old new unused stock. ![]() You guys maybe we wondering what is the RZ tank doing with the RD tank? ![]() Well, for some reason the epoxy internal coating on the RZ failed and had to redo it. ![]() But instead of redoing epoxy coating we applied something else this time around ![]() This product was suggested by Sumant’s painter who had used it earlier on a tank that belonged to a Parsi gentleman and had asked the painter to apply it on the interior. Its made in the US and is quite expensive 6k for 236 ml which is good for a single tank. Luckily I got a good deal for a 946 ml can on Amazon. ![]() This is how it looks and we have still lot of quantity left after applying on the RZ and the RD 125 tank.

Distinguished - BHPian ![]() ![]() | Re: My Barn Finds: Yamaha RD 125 & RD 200 Maiden ride on the RD 125 and the RD 200 growls even louder With the engine now running, we could now focus on finishing up the cosmetic bits and especially the seat. My OE seat was rusted beyond repair and I couldn’t find a replacement one on Ebay. So, we had no option but to fabricate one and the seat base chosen was of that the RX. The hinges were made in house and days were spent in just getting the alignment perfect for the seat plate. Also, we had managed to make a spare key for the original seat lock which was opened and serviced and repaired. Once the desired alignment was achieved the seat was sent to a welder to weld the hing bolts in place and add extra metal sheet to extend the base of the seat plate to cover the chassis better. Once, this was done a coat of the rust paint used to coat the inside of the tank was applied. For the RD 200 we had applied fibre glass back in the day to increase the seat strength and prevent it from rusting and that is still holding up well. Next, the seat guy was called with the foam to make measurements before he took the seat base with him to finalise it and apply the seat cover. Now, the bike was ready for its maiden run and it had to be prepared for its proper long ride as well as I had to visit the RTO with the bike to get its registration renewed. Since, this bike was lying around I hadn’t renewed the registration and fitness and I still had the original RC book. Last year around May I had handed over the documents to my agent and the process took really long as the records had to be pulled out as my details had not been captured in digital format and there was another issue with the engine number which was not common. More on that later. Now, with the papers processed the bike was required for a physical inspection and my agent called me in late December last year enquiring on the progress of the build and when can he made the necessary payments to get an appointment date fixed. With all the delays the day came in really close as my agent was away in May and wanted to get the work done in April and I had only this week as I am travelling for work in the last week of April. So, the bike had to be ready at any cost and I took for its first maiden spin in the complex and then out on the road. The bike rode and sounded beautiful but the carburettor setting was not perfect. These are very old carbs and had deteriorated quite badly especially the carb bodies. So, even with new internals they were a pain to set up as they would go off with smallest of inputs and we also had to to block the choke off completely as it had a leak even in the off position. So, we did our best to get the bike working and I set off to the RTO office with a small prayer. A few kms in and the rpm started going up on its own when the clutch was pulled in and especially when the bike was put in neutral. I didn’t want to touch the carbs and I managed to reach the RTO office somehow. The bike immediately commanded attention from folks present there and they couldn’t believe that it is a 1979 built motorcycle and especially that it is not an RD 350 and a RD 125 with twin cylinders instead. There was a brand new Ducati V4 on a flatbed which had come in to get registered as well and all the crowd was gathered around my bike instead ![]() Now, I was hoping that I would be done and out of there in 30 mins as the place was really dusty and plus the heat but, then things don’t happen so easily for me do they. I had mentioned that my engine number was unique and that was a reason that delayed the paper processing at the backend in the RTO. Now, that same issue came to haunt me when the RTO officer saw my paper and immediately said this has been re stamped and he can’t pass it. Firstly, its not easy to re stamp the number on the engine block and get the factory groves as well and the other issue is when the engine and chassis number are completely different when a donor engine or chassis is used. But in my case the engine number is just a three digit number for some weird reason and that is what was mentioned on the original RC book as well. The RTO guy was not even ready to listen to our argument and then my agent said that I will have to bring my bike again in May. Now, I was in no mood to go through this ordeal again and said try and convince him and do whatever it takes and I will wait it out till we get the papers signed today itself. So, a 30 min job took over 2 hours but the work was done. Now, came the difficult ride back home as the bike would just not idle and the fuel mixture was feeling lean as the gear shifts had done harder and the rpm continued to rise. Managed to get bike back to Tony’s place and when we checked the carb the left cylinder was running a rich mixture. We did a lot of changes to the air screw mixture and needle setting which made the fuelling much better and the bike more rideable but still it was not 100%. So, now we have decided to see if we can fit the RX 100 carbs instead as that setup is working beautifully on the RD 200, but then the RD 125 is a much smaller engine so need to see what best can be done with the 20 mm carb to replace the OE 18 mm ones. Speaking of the RD 200 I rode that to Tony’s today and the new clutch plates has made that bike into a complete beast with everyone turning their heads the moment I approach or do a fast overtake. Its a proper missile on two wheels but I felt it had room more improvement and especially at the top end of the power band. So, the main jets were drilled to the next bigger size and what a world of a difference that has made. The intake growl has grown louder and the thing just moves like a mad two stroke on the slightest of throttle input. Just love it.. ![]() Some pictures….
