Ive had my bone stock blaster 1 for about two years, it runs grate but i bought some buoys and now I want to race the spec class, I need help with what performance parts I need. So far ive bought a jd ride plate, worx wr201 intake grate, and a 11/17 hooker impeller. Im trying to find out the motor work I need to do. Also the ski ran great sense im in there should I do a pump, midshaft motor rebuild? Also can a single carb 61x be competitive, any help would be great thank you
