A 330 racing bore kit.

 

what is a 330 raceing bore kit and how much would it run me?

 

It bores your motor to about 330cc's. Look in a dritwheels magazine for priceing. And if you get one I know one of the modifactions you must do is a new more pwerfull starter.

Theres better and cheaper ones.

 

Well, what type of racing are you gonna be doing. B/c you said xc motocross. Huge diff. If you race mx you would want 18 inch tires in the rear, and prob. change your sprockets. And if your doin xc, 20in. tires and up, and still prob. change your sprockets. Most of it depends on the racing style. And if you do mx, and the dirt is hard/tacky/packed (most local tracks are). Get turf tamers, or any kinda grovable tire instead of holeshots mxr's or tires like that. They work much better in these conditions, but ifs its really muddy and lose, id go with holeshots, or a tire like it. And in dirtwheels, the bore kit is made by scary fast and cost like 295 or sumthin.
