I had a leak from the tank, but on the other side where the fuel sensor is inserted in the tank. the reason was a defective gasket. (O -ring)

Another recent is issue is whenever i get a FULL TANK done, and park the bike on the side stand, a decent amount of petrol leaks out from the main cap on the tank top. Hate these small niggles. in 2010, why cant they make a tank lid leak proof, atleast at an angle. :(
Had this issue on my machismo also. looks like RE is not paying any attention to details, but are trying to cash-in on the latest craze. Man, fuel is not just expensive, but its precious and little of it is left. They should try and give us products which prevents un-necessary waste of fuel. And Mr S. lal in his latest interview is been bragging about the future of urban transportation / green design and what not. Would advise him to practice before preaching.


BTW, have been testing the FUEL ECONOMY on my C5, full tank to full tank. Have done is four times, and the average economy in city riding comes to 28.5 kms per litre of Xtra premium petrol. Planning a goa trip next month, would test the economy on the highway than.

Nasir, are you Off to Goa for the RE Rider Mania, or your personal trip....?
Any more news on the development of the seat and silencers....?
Cheers

I am facing the same. The screw has been tightened using an allen key, however it still persists to some extent. Not that there is a a drip but there certainly is some amount of fuel seeping out.

It was me. Here you go,

@Nasir-You are overfilling the tank and thats why it spills out. I have the same issue if I fill it up too much. You can only put a extra rubber on the fuel cap to avoid the spill.

First of all thank you guys for sorting this out.

Today I opened Primary drain plug (The one with the filter), found the oil was clean. No marks of water in it. So thought to refill it. BUT my devil mind asked me to open Secondary drain nut :-). I knew that nothing will be there as almost all the oil was drained. So I opened the drain plug and VOILA almost 100ml of water poured from there. I was freaked out. This means that the water was settled at the bottom of the engine as it's heavier than oil. Tilted bike sideways to drain remaining oil (water).

Then immediately removed oil filter replaced it with new one and filled fresh oil. Now I can sleep with a calm mind.

Guys, what's the cost of Motul 3000 4T Plus 15W50 API SL JASO MA in your city?

[Randhawa]

@Hemant- Nice job you did today You just saved your engine and gave it a healthier heart.

I think the price of M 3000 is around Rs200/L.

[bradhey]

The mileage on my C5 has been gradually reducing and has come down from a healthy 33 kpl to 23 kpl.. Can't figure out what's wrong. There are no fuel leakage, park my bike in shade, I have changed fuel station to verify. The tyre pressure is always good.

Could it be a choked air filter or problem with Fuel injectors...........????
The spark plugs are not sooted either......... please suggest areas I must look into...!

Overfilling?

Even a 12 Rs Bisleri bottle when filled to brim and capped tight does not leak water, even when tossed in air. Why cant RE make leak proof tank lid. We are not even tossing the bike in the air like the bottle, we are just putting it on side stand (provided by RE itself). I understand that there might be some breathing required to avoid vacuum/pressure-difference in the tank, but i guess the Key-Hole could take take of that. We, the users take it lying down all the un-refined details RE throws at us. Sometimes we even go to the extent of justifying their mistakes. :(
my suggestion: If RE cant redesign a leakproof tank lid, they could just reverse engineer the capping detail of Absolut vodka bottle. its a simple and effective design, locks with just half a turn, and never leaks a single drop of vodka. Although they might not mix well, but petrol is almost as precious as vodka.

I was getting the 'full tank' to calculate a realistic idea of the mileage. Will fill a bit less next time onwards.

@ Bradhey:
Goa is a general trip, and not to attend rider mania. Have not dome any long ride since getting the C5. Going with another friend (on Machismo 350). plan to cover not just goa, but places around it, namely mangalore, jog falls, karwar, etc. tentatively leaving on the 6th from bangalore. Hey, when is the rider mania?

Seat, i am pretty satisfied with the current setup. Not much development on the silencer. hopefully next week sometimes.

@ randhawa:

am quoting a fellow rider RAJITH from another forum who just got a k&n installed. Do share your thoughts on the same. Following is his experience of the K&N.

Thanks Nasir.. Btw I installed the K&N air filter. I havent done any custom plumbing to incorporate the crank breather. Coz the current design is to cut hydrocarbon emissoin and its directed into the intake manifold hoping that it wud burn in the combustion instead for dropping down on to the road. I say this with confidence coz I spent more than 2 days researching on this. Right now I have the stock filter in-place which will continue to provide filtered air to PAV and crank-breather. I have close the hole which does to the intake manifold from the tool box with a nice rubber sheet. I feel that previously the oil vapor sometimes even droplets gets into the combustion chamber and thus fouling the sparkplug. anyways thats only my theory. but im sure these oil vapor gets deposited on to the filter and clogging it on the long run. I fill verify it when I go for a ride this weekend (700+km). Regarding the upswept, I think the shape itself provides some restriction. I checked for any baffles by inserting a flexible steel wire and it seems to come out thru the other end without any trouble.

Right now the K&N is fitted on to the throttle body via a 4" rubber tube (cut the OEM tube) so that the filter itself is placed in a dirt free zone behind the airbox. I know its dirt free coz the rest of the bike is a mess due to rain riding and this portion alone is very clean

Initial feel is that the intake roars is giving some sort of goose bumps. At lower RPM its thump, thump and as the RPM increases its RRROOOOOAAAAARRR!!!!

[indian21r]

hey guys long time since I wanted to take some pics of the bike. Here are a couple of them taken on Kamshet, slopes of hell ride

Realized after the ride that there was nail with which I drove for more than 150 kms. Hard compound has some use

[BIG SARAN]

That second pic is beautiful. The colour of the bull is mesmerizing with the flowing grass, clear skies and the mountains behind. I hope the nail wasn't that bad.!!

[indian21r]

True man that one captures the bike at its best. further it is also somehwhat like the color that they had in RE broucher.

I got a new tube. Since I drove for a long distance, the tube got multiple punctures. Lucky that I was not stranded any where.

[Randhawa]

@Bradhey-Can you get the compression pressure checked on your bike?Whats your ODO reading?Did you thought of getting the head decarbonized lately? Dirty filter and improper spark plug gaps can increase fuel consumption.

@Rahul- Looking sweet Are the Damper pads on the engine head taken of intentionally on LH side? Engine looks far better with them taken off with no ill effect.

@Nasir- I dont think RE will bother to reduce crank emissions as they are answerable for the exhaust emissions only.

There is lot more to the crank breather then simply for re-circulating the unburnt gasses and oil vapors to be burnt up in the combustion chamber. There are so many types of crank breather systems(inc charcoal filled canister to absorb wasted oil vapor) that if you dig deep into them, you will find a lot of different reasons to keep the existing plumbing intact and use it for performance gain(is it really the case on ours?).


Increased performance by increasing crankcase volume (reduces pumping effect).
Increasing crank case volume reduces pressure inside the crank case and help in engine making more power.
Fitting crankcase breather into the air box increases the crankcase volume.

Although as much as I wanted to keep the piping stock on C5 but due to recent development with engine trouble on my C5, I am forced to contradict my own statement.

First is very simple fact which did not even occurred to me until someone on US forum mentioned it and I feel so dumb about it knowing all along.

I wanted to keep the intake tube length due to a very simple reason of air turbulence which can effect the MAP sensor readings(while saying things related to MAF but speaking of MAP). But what skipped my mind and did not occur to me that MAF sensor works by detecting the air flow and MAP detects the absolute pressure. Turbulent air has no effect on MAP sensor because its not directly attached in the path of the air flow like we have the MAF sensor on most of the Petrol cars just after the air filter.

Now we don't need to consider the effect of turbulent air and we can do away the reason to keep the length but I like the spot I had chosen to fix the filter due to the fact thats it much better protected from the elements in that corner.

If you remember the picture I had posted a while ago of the dirty throttle body which I cleaned it and put it back. I found a lot of sticky black soot inside the throttle body which I assume was from the oil vapors and blowby gasses. If those oil vapors are lubricating but not burning or keeps collecting inside the combustion chamber then we have some serious problems which can result in poor starting, rough idle, poor fuel consumption. I have de-carbonized the head enough times to say that the carbon was in excess with some 1mm carbon on piston top at few places.

Using tape on the intake is a big no-no for me and butchering the intake pipe is not I would like personally.

So my next plan is to install a K&N crank breather on the breather pipe and probably with a K&N filter straight on to the throttle body or use the old plan but without incorporating the breather pipe into the intake. I will monitor the rest of the parameters and decarbonize the head after certain KMs to conclude if excluding the breather pipe from intake is a far better option then keeping it.

My engine has developed serious problems again and not one but three issues at once, one issue is related to the valve. Two other problems are connected to the bottom half.
Although they have offered to rebuilt my engine for second time but I had enough.

So far two mails written to RE has gone on deff ears, their engineers are incapable of diagnosing the problem although I know what it is and I gave them plenty of opportunities to rectify and even two RE UCE specialist came to try fiddle with the engine but failed miserably.

All I asked from RE is to give me a new engine as I had same problem occurring twice at almost same ODO intervals and if they can't then why not and why am I having same issues again and again. I am so frustrated with RE that I plan to put my bike on fire in front of their RE dealership in Chandigarh on 13 November and before that I will park the bike in front of the dealer with everything in detail for all the present and future buyers to have a insight into owning a C5.

By the way leaking tank cap is least of my worries at the moment:(

Anastassia.... First you want to ditch her and go to Canada... Now you going to burn her alive... ! No Please.....

[bradhey]

@ Randhawa: My bike has done 5500 kms so far. No I have not checked the compression pressure, but it seems good going by the kick lever. Spark plugs were checked only recently. Seems like the Air filter could be the culprit. Will change it and advise.

RE is not leaving me with any options here. What should I do with a bike I can not ride any more as I get too embarrassed at traffic lights when people stare at me due to the engine noise and giggle knowing I spent 1.3L for this piece of machinery and I spend sleepless nights. A company pledges to a new customer with a trouble free ride but backtracks on it and shows its incompetency to even diagnose the problem and leaves you bone dry to sort it out yourself and live with it. A guy like me who has no engineering background and bought a bike first time in his life can diagnose a problem but at the same time RE engineers who have plenty of experience and trained on the engines can not. Where do I go then.

RE is suppressing my passion for riding and faith I had in their company due to their history. I need some way to vent my anger, frustration and harassment they have caused me. I want to forget it as a bad experience and never ever think of buying a RE product in my life, thanks to their arrogant attitude. I hope some commonsense prevails and they work things out for me but that needs to be seen.
