Blaster 240 big bore kit
 

Hi all I was just wanting some insight wether or not to purchase a 240 big bore kit for my blaster. I clocked it at 61 mph the other day and i still want alot more power. I have a boyesen rad vlave, fmf full exhaust, and k&n. Has anyone driven or owned a blaster with a 240 or any big bore kit. Whats the difference between that and stock and whats the reliabilty of the kits??
any suggestions are appreciated
