Dean644

im looking for a big bore kit or maybe a high compresion piston to fit to my xf650 engine, which i believe is the same as the dr650se, hopefully somone can clarify this? and maybe a different cam. the bike is a ccm 644 which uses the xf motor, i know ccm have there own kits but these are hugely expensive so im looking for an alternative. thanks in advance Dean

wouldnt the hubs just flop about in the middle of the rim:busted:
