Still using the old coil. I dont think its the coil.

The plugs seems to get fouled very quickly so the mixture is either very rich or the rings are not seated properly.

Cleaning the plugs solves the problem for a few days.

Have been unable to use the bike for a few weeks due to an illness but will get it checked out next week

hi

if your plugs are fouling.there could be a couple of issues,all are interrelated and will have to be checked.

1.if you have an issue with the electrical energy available at the plugs for combustion.This could be due to a problem with the coil, points,condensor or battery.
2.if the ignition timing is incorrect (too advanced or retarded)or the point dwell is set incorrectly you will have the spark too early or too late and the spark energy will be low.
3.if your plugs are of the heat range this will add to the fouling problem
4.your carb is incorrectly jetted or tuned.
5.if your valve timing is incorrect
6.if the valve clearances are incorrect.

@ Sanjay: This is the first time that I have gone through this thread. Very interesting and excellent restoration. When I was browsing from page to page the colour really didn't appeal to me but after seeing the bike restored, I must say that it looks good.

Has the stalling problem been resolved? Again, congratulations to you for a great job

After seeing the time your bike and Karl's has taken to get completed, I now believe that patience during a resto normally results in a better outcome.

@Karlosdeville: Many congratulations on the completion of the restoration even though I am late in doing so. Really like the colour. Have you gotten any more work done with reference to the oil leaks?


Best Regards
Prithvi

@Prithvi: I still dont like the colour and will probably repaint it after getting all the mechanicals and electrical gremlins completely resolved.

Yes. Any restoration you need a lot of patience. Better to get it right than to do a rushed job and have to rework it.

You may have oil passing through the rings/piston or through the inlet valve stems.

Posting after a long time. I think we have finally resolved the erratic misfiring that was plaguing me for a long time.

Main cause was a poorly serviced distributor. The mechanism behind the points area that controls the advance/retard when the bike is running had not been properly cleaned and greased so was probably sticking causing issues.

A good clean of that and some lubricant has improved the bike tremendously.

Also swapped out the Amal carb for a Mikuni. The bike feels like it has new life breathed into it.

Will keep the Amal for show days but daily riding its the Mikuni for me.

Hey Sanjay, I had a 5T long back it used to give the same problem of stalling after it gets heated & then starting after it cools. We diagnosed the problem to be the condenser. Replace the Ignition & condenser with original Lucas (Indian made Lucas), the issue will be resolved.

Hi Jagadeesh,

As I said in my previous post. The problem was the distributor mechanism not having been serviced properly. Points and condensor are new so that was not the problem.

Anyway bike is running well now.

I took it for my first long ride upto Mudaliarkuppam Boat house on the East coast road on Sunday morning. About 80+ Km each way so an approximate 160km run. Kept the speed to 40Mph (approx 65kmph) and bike ran just fine.

Met up with a lot of other bikers there on a wide variety of bikes. Nice weather and great ride. There was another Triumph owner there on a beautiful Triumph Rocket III. That is one monster bike!

Have made a number of trips to Mudaliarkuppam with my baby.

Engine is close to being fully run in.

She is running well with the exception that the right exhaust keeps popping off the engine exhaust port!

Not much fun trying to fix that back on the road.

Not sure why it is doing that will try adding a shim and see if that helps.

Next steps:

• I have got the original Lucas PRS-8 switch. Need to rewire the bike to use it to prevent the overcharging that is happenning now.
• Also have a new set of brake and clutch levers
• Try to prevent the perpetual oil leaks!!
• Tweak the jetting to get a bit more out of the top end after the run in period.

Sanjay,
You have a British Banger and it has to mark its territory . Don't waste too much time with it. Even my 2009 Bonnie has to let go couple of drops once in away, especially when parked after a long ride

Get a tin tray and put it under the bike to keep the better half happy with a clean garage

Enjoy your bike

Best Regards & Drive/Ride Safe

Ram

Hi ram



the banger has sure marked all of its territory!

Cheers

I cannot seem to source a proper Air filter hose that fits my speedtwin.

Any folks on the forum know where I can get a rubber hose that will properly mate with my carburettor and fit onto the air filter (Half moon shaped air filter box under the seat)?

sanjay ,
Do you use the Amal or a mikuni,getting something for the Amal may be tough as the AMal side has a slit into which the rubber should lock on to ,Are the yezdi ones too short ?? maybe you could try a vijay/labretta one and cut off the bent side of it and mate it in .

You mentioned the PRS8 switch ,can you let me know from where you picked it up ,need one of those for my Tiger Cub .

Thanks

Prashanth,

I have both a Mikuni and an Amal. For my daily use it is the Mikuni so that is the one I am looking for a hose. I will look at the Vijay/Lambretta hoses. Not sure what they look like.

The PRS8 switch was sourced from the UK. burtonbikebits.net

Oh Ok, for the Mikuni you would need a hose larger mouthed on the Mikuni side and smaller on the air cleaner side, do you use a paper element for the air cleaner?
Looks like the only option may be to use a car radiator hose and cut it to the required side and fasten it with some clips - the only issue I see is that the radiator hoses are not too "flexible" and hard to fit it in.

The only other hose which is pretty long and flexible is the one on the Royal Enfield classic 500 EFI, the air box hose do take a look at it - it runs all the way from the throttle body and behind the pseudo airbox/tool box to the side box. That should work.

Thanks for the details on PRS 8 will try and order one.
