i was out doing some standups on the highway and my bike started to blow smoke out of the exhaust i shut the bike off for a while then started it back up lots of smoke and oil came out of the exhaust i pulled the airbox cover off and it was full of oil anyone ever heard of this??it's a 03 r6

 

My SV done the same. The oil catch tank on the airbox over-flowing into the main airbox then being burnt out through exhaust... mostly when starting up from cold.. lots of white smoke.

Cleared the oil out and all was sorted, but now selling the bike to get something more suitable so haven't really fixed the problem, but I was told to just move the oil catch tank and it shouldn't over flow...

 

Common problem with those. Do a search there are a bunch of threads dealing with that problem
