I on my stock blaster can beat my buddies up to mid, and then we are even to top, and his has fmf pipes, reed spacer... is something wrong with his?

I need help looking for tires/rim set, Ill be riding in a gravel pit, dirt track and grass doing wheelies and stuff... does anyone have a particuliar tire you especially like?

 

i personanly like the holeshots on the blaster and maybe your friend was afraid to go to fast i dono though
