bore kits

bore kits are for more power. usually people will put bore kits in because theres not enough power for them or there to big for the bike so they just bore it out so they don't have to pay more money for a new bigger bike. bore kits do make a big difference because 250 can be bored out 280 or a 283, so that's putting another half of a motor on your bike. to me doing a bore kit is better then having to spend more money on a new bike.
