So sent the crank off for a rebuild as the engine was full of water on arrival, hence the massive strip down, and have been told the crank web with the fixed pin is worn beyond use and guess what?
You can’t get the part and no one has started producing one. You’d think with Suzuki offering the vintage parts programme they might produce a few engine parts to keep two-strokes running.
Alternatively no one is even offering a service to machine the pin out, so that you could press in a pin like on the other side.
I’m amazed, particularly as I used to be a precision machinist years ago, I’d estimate maybe a couple of hours work tops – machine off the pin and then bore to suit the pin. Should be doable on a quality lathe with a 4 jaw chuck or a jig bore.
So currently the bike is a write off until this issue is sorted, if at all. Crank builder told me he has 3 other customers with the same issue, FFS.
My advice is don’t buy a Mk1 or 2 RG250, on top of the crank issue, you also can’t get head or base gaskets.
Should have kept and finished my 350 YPVS, before COVID and old fart taxes pushed prices through the roof, SIGH!
