i have had the same blaster for about 10 yrs. the oil pump failed after a fresh vitos rebuild(seized within and hour of easy riding) 5yrs ago. now i have the money to fix it and need some input. i have searched for more info about the firebreather and all of the big bore kits but i cant figure out how much more power it will give it. i plan on port polish,+3 crank, extended a arms and swing along with shocks. i do have a toomey b1. any info and suggestions will be appreciated
