my monies still on pilot jets.....worth draining carbs first though 

I wouldn't have thought it was the pilot jets.  According to this:http://www.dansmc.com/carbs2.htm it would be the pilot/idle jet.  But since it goes away when it's warm it would be unlikely?


I'd have thought it would be a choke/richness problem but anything where you could get condensation going from cold to hot and/or water would be a fair bet too.


please let me know if you want any more uneducated guesswork, I'm always up for talking knowledgeably about things I'm Ignorant of :-)

mmmmmm....yes good point about starting ok when warm    pilot/idle jets work on tick over and then the main jets take over.......so cold starting problem and no recent changes to bike,i can see why you think contaminated fuel.....very interested to see the outcome of this one
