Ok.. been looking around little.. so much nice engine parts over there so it is hard to make up my mind..lol Rd/Rz is the same i guess with the ypvs system.. and i have couple of them lying around and also 2 500 engines to. What i want is an "bullet" proof bottom end +4mm crank with the race bearings and trued/welded. If i stay with the stock cylinders how much power would they be making on pumpgas ported and a fresh bore?? Any ideas on porting sice it gonna be in an MX bike? And what gear ratio should i have on the straight cut gear for the clutch basket? And a good thing is that you do international shippings on parts.. That is good for me.. /Mikael

Thank's Jared!! Seems like a guy i will deal with when it gets time for it.. Stuff i got is actually an RZ350 engine that was a good runner before i sold the chassie and keept the engine. There is no other than jolly moto pipes and some jetting and a little milled head. Going to have it rebuilt and vith a longrod +4mm crank, got a pair tmx34 mikunis to go on there when it is time for running. So.. well.. to leak little info about the bike is that the engine will be in an yamaha wr400-426 chassies that will be set up for long gravel road and offroad riding and will be competing against 450 mx bikes. How much power is in an 4-stroke 450 mx bike btw?? But i wanna go 2-stroke as i think it will be a fast bike.. /Mikael So that is why i want reability of it and there will be good maintiance offcourse to let it live long.

Wonder little about the differences on the cylinders thats out there. The powervalves and non and how long does they last and power output from them in trailport configuration. And what is the difference in the longrod +4mm crankand stockrod +4mm crank and benefits? What i want is an engine that is having a good powerband upp to topend and what rew numbers and max rew on the engine? Any inputs are welcome.. /Mikael

Well.. i was just curious about how it ended up since it was a while back there was any post to the thread.. *s* What model and size of the turbo are you using?

any uppdates?
