If you're talking about a standard for 450 With bolt on mods, and maybe a valve job,a ported, high compression oem cylinders on race gas with pipe/porting match have done that.. But a high comp, race gas 310-330 on race gas should take care of that.. a 350- 4mm is a great combo for what it sounds like your trying to accomplish..

363 Sphinx from Arlan is a great way to go. Gonna cost you 3500 prolly

When your buddy's not looking hang a 100lb tractor weight off the bottom of his frame. That will help you beat him.

Hold it pinned when he lifts works for me especially in the dessert. With that being said suspension does wonders. We're u riding? Take him out to JAWBONE CANYON and find a long river bed. HP is nice but most people can't use all of it everywhere they ride. R,s have a great advantage being six speeds.IMO.

ok so a 330 or 350cc should do it. and and for spending money, im doing that..

Who's going to be setting up the motor? Port work? Carb? Pipe?

If u have the budget go 431 puma, lot of good shops who can build u one. Hybrid, shearer, k&t racing, Packard all great builders. My sphynx is really fast but a couple of the big bore 450's got me at the hassy drags. I beat most but the real high dollar ones were real fast.
