na we only have ONE pre 75 vmx round in Sa now, so i have set all my bikes up for flat track there is like 5 rounds plus ride days, and still trying to get some more frames to build some more flatty's, so i would just change that rear and bean it, be perfect !
its the 4 stroke part that i cant get my head around, all those gears ans chains and shims and ...............zzzzzz. i cant understand ow they work or ow to keep em running.
but still nice bike.
