I think the website is www.psiperformance.com

I've heard good things about there motors, but I've heard they are rather difficult to get a hold of.

If you get the engine and want a dome, I have a PSI Dial-A-Dome for sale...

There's one on ebay right now I think..

I don't think they are worth it... ticking time bomb if you ask me.. Not sure what kind of riding you're doing, but I see you already have a 330.. Just stroke that puppy and bore it out a wee bit more..

if yur gunna spend that kind of money get a midcal racing setup, its a billet topend that goes from 465cc's to 550cc's and they sell a complete kit. or the famed saber racing kit.

the midcal one looks way nicer but they actually perform about the same as a saber kit. both are about the same price ranging from 1700 for a bare topend to a screaming well over 100hp ready to race setup at around 4000$. and every option in between. i think they both claim 80+ hp on pump gas.
