Blaster for 450 class?

BlackStar

Im from a motocross background. Raced for 20yrs. Anyway decide to get a quad and bought a blaster. Ive been having a blast on it. Decided I'd like to try my hand at racing quads now. Was going to sell the blaster for a 450, but after riding my buddies 450, I prefer the lightweight flickable feel of the blaster. Obviously a blaster is way out motored by 450's. So, I thought a ported 72mm topend with big carb and watercooled head might do the trick. Anyone here race their blaster in the 450 class? Im either going to build my motor or swap to a late model yz250. Would prefer to stick with the blaster base just due to ease.

i believe 245 stroker races with the 450s but his is pretty built
I would say if you want to keep up with the 450s get a 240 kit and a +3 stroker then talk to angus kennedy at kennedy powersports have him port it.
He is making some sickly great power with blasters

there's a guy who put a yz250f into a blaster and it looked pretty clean. with a good ported top end and a stroker crank, you may be able to be competitive. as you already know from your experience, gotta get the suspension dialed in. you may be able to out ride some of those guys as well

Yes, suspension is what Im working on now. Ive got a swinger, arms and reworked yfz450 shocks on the way. Motor wise, Ive ported the cylinder, added toomey exhaust, .5 reed spacer, tors eliminator, k&N, etc. It runs tons better, but I know I'll still be out motored.

It would be like bringing a knife to a gun fight but anything is possible.
Def get a mid range port on that 240 and hope the track is short with lots of twists.

Yeah, Im thinking I might be better off with a motor swap then sell my motor to recoup some of the cost.

A motor swap would probably be your best bet. You will have a tough time keeping up.

At the track that I've run, the start straight is about 200' and I can hang and out run most of the modded 450's all day long. Since the blaster turns so much easier I've found myself stuck behind them going through the corners. If you wanna run with them and keep your blaster motor, your going to need to mod the motor quite abit but it is possible and do-able.
