find reputable workshop to upgrade blok, cam, carb, clutch, sproket

change blok only not much different

buy good quality piston and piston ring, usually those cheap blok came with low quality piston, piston ring

back in 2003 upgrade my EX5 with 53mm racing blok and carb RX100... couple years later changed to ori blok and rebore to 53mm without resleeve, high cam, carb wave125. used this spec till now
