Smokes A Lot

[kookennay]

I FEEL LIKE MY WHEELER SMOKES MORE THAN IT SHOULD. LIKE WHEN I FIRST START IT SMOKES A LOT BUT GETS A LITTLE BETTER AFTER I HAVE BEEN RIDING BUT NEVER REALLY GETS BETTER. JUST IDLEING IT SMOKES EXCESSIVELY. WHAT CAN CAUSE THIS. ITS A RESLEEVED CYLINDER 72.5 BORE I MIX IT 36:1 NOT SURE ON THE CARB IT NOT STOCK IT A PWK THAT SAYS 71A4 NEJ ON THE SIDE. ANY HELP WILL BE APPRECIATED!

could be excessive oil build up in the pipe (from a previous owner running it way rich) or it has the right side crank seal leaking and burning crankcase oil.

I JUST HAD THE PIPE OFF AND CLEANED IT OUT AND REPACKED THE SILENCER. HOW WOULD I KNOW FOR SURE IF IT THE CRANK SEAL. AND COULD IT BE IT JUST NEEDS A REBUILD? IT BEEN OVER A YEAR ON THIS TOP END BUT I CAN'T REMEMBER HOW LONG IT BEEN SMOKING LIKE THIS.

you would have to do a leakdown test on it. Where you block off the exhaust and pump air in the in the intake (I built my own with a quage some pvc pipe and a expandable rubber plug) I think it has to hold 6 psi for several minutes. If not you have to start listening and looking for leaks. I hope this makes some sort of sense maybe someone else will explain it better.

YEAH IT MAKES SENSE I GOT TO PULL THE CLUTCH SIDE COVER OFF ANY WAY TO FIX THE CLUTCH, IS THERE ANYTHING I CAN LOOK FOR IN THERE TO SEE IF IT A SEAL LEAKING?

[89rwfo]

well i dont think it will be anything obvious that you are gonna be able to see.

there are a few things that'll cause what you are experiencing. a pilot jet thats too large, a plugged overflow tube in conjunction with a seeping float valve(allowing fuel to over flow into engine), a float thats set too high, a clutch side crank seal and/or a center case gasket.

the best thing to do is to research doing a leakdown test and double check the other ares i mention.

Reeds stuck open or broken possibly

[kookennay]

IT RUNS FINE AND I DON,T THINK IT WOULD BE THE PILOT CAUSE I DON'T THINK IT USED TO DO IT. DO I HAVE TO SPLIT CASES TO GET TO THE CRANK SEAL OR IS BEHIND THE CLUTCH?

[86 Quad R]

no need to split the cases to replace the seal.

incase you need reference to do a leak down test go HERE
