Default Re: grubee skyhawk 66/80cc

For reliability 4 strokes are the answer. But I have a problem with the way my banking is set up, Namely, Ain't no money in it. So, like you, I go 2 stroke and just make sure the the top piston rod bearing ain't a bushing. THEN, I always run a little heavy on the oil mix cause I figure the little china girl needs all the help it can get. The best way is to make sure all the bearings are Japanese and not chinese.
I would still run just a little heavy on the mix "just cause". I've been running heavy for YEARS and have NEVER melted rings to a cylinder. And after the normal upgrades, ie, plug, wire, ect, I've also never had an engine not at least get me home, (knock on wood.)
