One of my exhaust pipes smokes way more than the other. I assume this is just a carb tuning issue. Can somebody confirm? Thanks

sounds like your carbs are outta sync. are they stock carbs? ask big red

If its the right pipe might be your crank seal just had to replace mine and sync the carbs ran great after work was done. just an idea :blush:

What color is the smoke, and does it smell like 2 stroke oil? Which side is doing it?

 

It is definitely 2 stroke oil burning, and it is the right side that smokes more.

Yes it does, when I jump on it there is about 3 times more smoke out of the right side.

 

have you had your carbs out recently. If so try changeing the slides to the other carb, sounds crazy but the same happened to me

I was hoping the carbs were just tuned differently and one was running richer than the other. Is this a possibility?

Well pull the carbs off and clean them. More than likely its a crankseal, but your gonna need to tell. It smells slightly different, and usually looks slightly different than 2 stroke oil. If if is coming out like a mofo, thats what it has to be. Other than that, check the compression.

Yeah, I have the same problem on my cub. I get noticeably more smoke out the right pipe, and that pipe is actually cooler than the left. When I check the plugs the right side is wet with no noticeable smoke ring, while the left pipe is hotter and dry with a perfect smoke ring. The motor was just rebuilt with the cubby, so the crank seal is not an issue and the compression is fine at 185. The thing that I was leaning towards was the coil. I think the right plug wire is not as good a spark or as consistant which would explain the unburnt fuel (blue smoke) and the wet plug on one side. Plus would not show a smoke ring if it wasn't burning the fuel completely.............

 

Just my .02 :biggrin:
