so this is a piston port engine from a 79 or 80 variant sl.
I rebuilt it with new bearings and seals. needs (pedal shaft seals still) hand cut case gasket. new cyl studs. No top end, but you wanted to use a puch top end anyway, am I right?
the variator side is disasembled because its missing the nut for the rear pulley shaft. (i misplaced it, might eventualy find it) The starting clutch friction material is also gone. I've seen people reline these with jb weld (im not joking)
has the correct swingarm for bolting this engine onto some non derbi frame.
one of the side covers is NOS in the bag from handybikes.
asking $275 shipped.
