EFI 2 stroke enduro bike.

Hahaha...yep. My 92 Honda RS250 did 82hp, but was hungry for parts when tuned like that, and revved to 12000rpm. But a big single like a 500 two stroke, has a really long stroke and they hate revving. When I road raced KX500's, I put a piston in it every time I raced it, as they used to start cracking pretty early.

Reading stuff like this is really putting a damper on my foray into elderly 2t's. Ooh well, might as well feel the fear anyway & continue wrestling the green ba$tard.

They're all good mate. You can get a whole season or so out of a piston/ring assembly on a big bore two stroke moto-x bike when riding in the dirt. It's just when you gear 'em to the moon and rev the tits off it all day thing start to go bad quickly!

Sminky. Looks like a new piston anyway & the bike is riding me mostly. Bet it's not as easy to whip the pipe of the Ossa.

From what is said above does it mean no more mixing fuel as the bottom and has separate oil delivery thats not a real 2 stroke??

Im guessing as the air flows through the crank it picks up some of that oil and that will be its lube. Like jet skis do......
