i have an 01 blaster. it is bored 80 over 3mm stroker kit im getting a toomy pipe. i was wondering if cool heads would be worth the investment as well as get a new cdi box and a hotter burning coil. im also have problems with it when it gets warm it will rev up not hitting the throttle and the only way it shuts of is if i get the rpms down or if i stall it. does any one no what is wrong with it. also thoughts on reed spacers. any help will be greatly appreatated.
