Good day Dwags,
I thought it be nice if we get a thread together where we add part numbers together foe a rather complete rebuild for a lc4 640 motor..
there is already a million threads on how to, but not one with a list of part numbers of what you'll need

would you guys recommend anything else, i am not sure i got all the bearings or gaskets needed, my water pump and starter clutch was recently rebuild...

i am ordering my parts abroad, (munn racing) so far i have saved R12 000 buying there than local KTM..

BTW, I think this is a good idea for a thread.

On what mileage are you rebuilding the bike at?

Does the 640 barrel get a nikasil coating?

rebuild at 60 150 very hard km's, tbh I am just buying the parts, alfie cox racing is doing all the building.. if it doesnt bleed i cant fix it..
