Jetting!!! Again and again and again!
Uncle pirate:
Always rem that smoking on a two stroke is usually related to the premix ratio...and from experience the"factory recommendations" for such are to save the factory from having to honor any form of warranty-implied or otherwise...when we raced, we ran castrol at 50-1,with no major wear issues...of course we were doing strip downs every other race,so we could keep an eye on any potential issues. Consequently, I consider 32-1 a max oil ratio,anything greater usually just means replacing fouled plugs(I don't like running too hot of a plug-and bp8es to drop the electrode deeper into the dome-it clears the piston and theoretically creates a better flame front...)when we ran (factoring recommended)20-1we usually couldn't make it thru a moto w/o fouling. I'm running team green specs w/168 mains...BelRay synthetic@ 40-1.plug runs tan-no oil fouls...of course I'm at sea level now,so a rejet is in order and I'm no longer running in 100+temp days.Im assuming (the smoke)is blue and not black of course...

given....... I havnt read MOST of this thread. but I havnt seen anyone discuss how premix viscosity affects jetting... :roll:
