big bore kits are rather useless. Just get an aftermarket cylinder and you'll be happier.

My buddy robert has a 450r that ran 4.3 in 100 yards, you'd be hard pressed to find a faster honda, or yamaha 4-stroke.

Im always working on projects afterburner

 

Is your buddy's 450R in a orange ridged stretch titanium lonestar frame?

 

Kelly's Craycraft Raptor ran a 4.2 but there was a lot of debate about the track. The DS guys are slapping each other on the back for a 4.3 run. I watched a stock weight Craycraft 730 Raptor run consistant 4.6s. The 4 strokes are getting faster but the 2 strokes are still king.

To me, the baddest "quad" is the Dodge Tomahawk. If I win the lottery, I'll have one.

 

The big bore kits are the best way to go for all out speeds ,my 404.25 cc kit will be just enough compression to spool up my turbo.Also a nitrous set up to spool the turbo earlier. Can't wait to smoke crotch rockets..

 

Please dont tell me this is the bike that is in 14mins signature??

OK, I won't. You're a bright fellow, you can figure it out.

what track is this and is it dirt or sand?

 

you can tell beachs is lying and its not that that setup and those numbers arent possible, its the fact that he said he had friends. [img]i/expressions/face-icon-small-happy.gif[/img]

 

There have been rumors about 4strokes running super fast times. But there are no timeslips or video to prove the numbers. I can show you a video of my bike running at the track, and tell you it went 4.0. But theres no way my bike will run that. I like having proof. Timeslips or video of the score board with the time posted. jmo.
