white smoke between gear changes...

[eezicar]

Hi all any help would be gladly appreciated.
Ive done close to 3500miles on my K8 turbo Busa, shes 350hp strong on 95 octane pump gas.
Yesterday i was out for a ride when my father on his turbo blackbird noticed a few small puffs of white smoke between gear changes on my bike He says this lasted for about 5 miles then went away, the bike still pulls hard so no loss in power also when i got home and the bike had cooled i put my finger in the exhaust to check for any oil residue and luckly i found none. The engine builder says could just be some fuel quality problem but im not so sure, any ideas??? The bike is now due for its third service, could this have anything to do with it or not?

Thanx all
 regards Mark...

before you went for your ride did you have the bike on the bike stand ?

i did have her on her stand and also would have thought that a bit of oil having gone forward would have caused the smoke issue but as was pointed out to me the smoke between gears only happened about 150 miles into that days ride....
Forgive the delay in response im several time zones away and also its mid winter here, we are south of the equator in South Africa, fortunatly it very seldom goes below 0 here and even when it does its most of the time still sunny...So everyday is still a riding day...
