i see some MT250 talk there--i have a CR250 points ignition system [minus coil/condenser under the tank]. Had an MT250 a couple of years ago, you'd laugh if you saw it when i found it lying out behind a disused dairy factory corroded to bits so of course the old 'you'll never get that going' said by someone, got me started. Ran perfect too without any cost & bolted it into an old yamy R5 frame as a test bed. went to a guy for a 'grass kart' in the end. We sold them new where i worked back then but get more exited about them now than then--sad that!!. Cheers.
