You can get some nice kits from ctracing.com. I knew a guy who had a 310 or a 330 non powervalve motor from them and it was really powerful. He used it for mx and gncc races. I just cant remember the size he had.

OH and they also have some info about which size motor fits your needs. So if your looking for a nice trail bike they recommend one. They have some drag motor kits and things like that to.

Yep, actually F CT. They use funky ass pistons so you always have to go back to them unless you buy a new dome, they setup the piston to cylinder clearence too tight and its easy to seize them when breaking in, and they also do a half assed port job. If your going to buy a Pro-X cylinder I would buy it from ESR and have them port it, which is decent for the price, or have someone else port it. Personally I wouldnt do either right now. I would just port the lil jug and wait on the sphinx, or just wait on the sphinx.

they sure are dicking the dog on the sphinx ,seems like people have been talking about it for a good while now ,i understand these designs take lots of R&D but its been hyped and i hope it performs like they say , i cant wait to see what it looks like ,i bet its a scaled down version of the saber which wouldnt be a bad thing .

Hey its all you damn banshee guy's fault they aren't out. I think its basically a Saber on a smaller scale, R reed cage and what not.

Eh, I already want one. I hope to have the suzuki project in motion by then so what little money I have will go towards it. The lil motor is really running well right now for what its built for, with the better pipe I think it would have given the old 310 fits. Not quite the same top end but it has a bit more midrange, I really like it. I will have one at some point though, just want another bike to actually drag with again. The R is really fast enough for trail bike already, Im bet'n its close to or at 50hp right now and I have a few tweaks up my sleave.

And yes I know, Offtopic.
