hello, just recently sold a mk3 LC125 :-(
i have an RD250Lc tho :-)
shame yours is a "square barrel"... (is it the early unrestricted 10W) as i have the powervalve motor and the wiring instructions for a "round barrel"....
i also have a YPVS exhaust that was fitted to an LC125 if you want to try it out :-)

will be good to see it out sometime.
youll keep up witht he rideouts.
