Just bought a 04' CRF 50 and put on the Tag Miniplay Bar kit, WRP red rims, Bridgestone m-40 tires, i-shock w/ resi, front fork springs, Sano skidplate, Sano tall seat with seat cover... I have the BBR pipe ordered. should be here next week along with the K&N air filter. Should i be able to tell any throttle response or top end? Also what swingarm should i get but not going crazy. Best for your money. Anybody know? and what bore kit should i do without ruining reliability but gaining more power? Thanks
