tonight im going to clean my jets b/c im sure thats the reason behind my running problem the bike will crank when cold for 15 minutes before it starts when i gun the throttle it spitts a lot (not backfire) but after running if i dont let it sit for too long it will start???? i was wondering what the best way to clean the jets are i was told some carb cleaner and an air hose?

 

Yamaha makes excellent carb cleaner.Does the job very well and is o-ring safe
