Engine running unevenly, bike lurching

[jdrider]

Sounds easy enough. I'll give that a shot before I fork out any money for anything. It would be nice it if was just a simple fix.

Thanks!

Bet you it is. Sounds like one of the NORMAL geezer idiosyncracies. :2tup:

Just one question. When does the lurching occur ?

[jdrider]

It's most noticeable when in 1st, but it's still intermittent going up to around 40-50 mph, just not as problematic.

It's constantly inconsistant - not just when shifting and such.

Sounds a lot like carb problems as others have said. I would also be looking at the chain for seized links which might be adding to the carb/engine roughness when on the road. For that matter, how new/old is the chain and is there a lot of wear on the sprockets? Old worn sprockets and a worn out chain will have the chain trying to leap over the teeth and cause lurching often enough. Not a good thing.

Chain is in good shape but I was thinking about doing the 16 tooth sprocket mod after resolving the carb issue. I may just change the chain then anyway.

If the chain and both sprockets are original you might as well change everything. That is my view on things but then I really don't trust older used parts with a possible bad maintenance record.
