Sold 272xp Crankshaft (found)

[Sepia]

I need a crankshaft for my 272. The big end bearing let go on mine, so I got a used one and installed it, and then discovered it is bent.

Anyone have a good one?

Seems like you might be in a position to make one out of two? A good motorcycle mechanic would press the big end out of both of them and assemble the good big end and con rod on your straight crank for a few bucks.

I actually never considered that. Are the ends on on the throw splined to maintain alignment of the two crank halves? We only have one motorcycle shop here in town. I would be real surprised if they had the equipment to reassemble my crank, but who knows, maybe they do it all the time.

I'm going to mark this threat "found". I have a used crank on the way and hopefully it is a good one.

No they are not splined but when assembled they use v blocks to align the halves. If the shop has any dealings with race bikes they will have the gear I would think. Anyway glad you found the bits you need. I have a 272. Great saw.
