Hello.
At start-up both exhaust blow lots of white smoke for a minute or so. Once on the move the smoking stops & doesn't start again until the bike is started again after standing for few hours & is then.
The engine was totally rebuilt about 1500 miles ago and has only had these symptoms in the last few hundred miles.
Initially I checked for wet-sumping. This was definitely happening but has now been cured, but this did not resolve the problem.
If the small amount of oil now gathering in the sump is drained, before start-up, then the smoking is significantly reduced.
I also noticed that the crankcase breather pipe (connecting from left hand side of crankcase below cylinder) is spluttering emulsified oil into the oil tank after a 20 min.
Any ideas?
Thanks
Mark
