After 1st time out to the dunes, I found just how slow the bike is. 310 kit is probably my next step. Any advise on where to get one would be great. Those that have the 310 please describe the difference from the 246cc to the 310.

Like I said, very new to the sport. Drag raced about a zillion times over the last wkend and the new 450's are dame fast. The Raptor is not as fast as I thought it would be, but way too many bikes kicking my azz. Time to spend some dough to compete.

 

you may want to go bigger than a 310 if you have the cash

 

Very nice setups here ESR. I haven't heard any complaints about them yet. I'm sure I will now that I have said that.

 

I've got a CT kit that has been great. The guys there set you up and it's an easy install. Check out CTracing.com
The difference was pretty substantal. The best thing is it adds on gobs of torque. It made the bike a much nicer and easyer ride.

The only reason I did not go bigger is that machining of the case was required above a 310.
