I have an interesting thing going on with my 1991. This bike has about 80k miles on it and runs fine. A little while back it started doing something interesting which I don't understand and was wondering if anyone else has had this and what they did about it? Occasionally (like once every dozen times or so) when starting the bike from cold in the morning I get about 15 seconds of blue smoke just shortly after startup. Then it goes away and isn't seen again during other startups or normal riding. This seems to be random in occurrence and also doesn't seem to affect the oil level that I can see. I generally start the bike on a pretty level surface on the center stand and use full choke to get it going, then back it off as I can. I did try something the other day the last time it smoked on start- I turned off the engine with the kill switch right after it started smoking and restarted immediately. Presto! No smoke on the second start! This has me baffled and so I thought I would throw my bread upon the water here, so to speak Anyone? Thanks for your time, I appreciate your input. Samdoggy
