Have you done any head work yet? If not, maybe you should think about a port & polish, valves, and a good cam (not a Hotcam). And maybe just do a higher compression piston, like a JE. You could save some of that $1500, and still beat them 450's and maybe one day if you lock the crank up you could get that stroker. Just my opinion.

 

You might also think about a spelling and grammer class.

 

Shocks?

 

Depends a lot on the type of racing. If you're talking about MX you'd better use that 1500 along with what you get from selling your raptor to buy a 450.

 

A high compression 686 with a good port job and a Stage 2 cam will put a major hurt on 95% of all 450s *if* you can get into 3rd gear. I had a MX Raptor with about $2500 in suspension and a Craycraft Racing Signature 686 motor. On straight sections or long sweepers, I could pass the 450s at will, just roll on the throttle and reel them in. In tight corners, I was clear off the seat almost sitting on the nerf bars and they'd still come around me.

Making a Raptor into a full blown MX machine is possible but you'll work twice as hard wrestling it around the track and spend 10x as much money to get the same lap times as a mildly modified 450.

 

And not all of us have the seemingly endless bank account that UBET has managed to produce. [img]i/expressions/face-icon-small-wink.gif[/img]
