For the gurus....

I have some light white, maybe blue, smoke coming from the rear pipe. Only at idle, and only when fully warmed. It's light enough that it's really not evident except at night when caught in a headlight beam. I just checked the compression, and it's 180 on both jugs (hot and WOT). I'm thinking valve seals. Also thinking since it's not heavy and the plugs look clean, it's not worth worrying about or fixing. Yet. Opinions?

 

How's it running when fully warmed up? Possibly a rich condition?

 

You could be right. The bike runs great. Had it dyno tuned, but the guy that did it didn't mess with the low speed jet at all. Smells fat at idle. Guess that could be the cause of the smoke?

 

If it smells fat and not like burning oil then yes, I would suspect a rich condition.
