If Yamaha decides the woodruff key problem is the result of a bad batch of cranks, would it be acceptable for them to replace the offending cranks???

Or, should they replace the entire motor??? Like Honda did with the VF500.

Why replace the crank? Is it getting damaged when the key shears? I'm sure the crank is the same PN for the YZ, so I don't see the crank as being the source of the problem, but that is pure speculation on my part.

More speculation: The problem is the WR stator doesn't fit the crank end properly.

Did you post that just to say "OFFENDING CRANKS"?
Does have a nice ring to it - maybe that should be our new race team name.

You would think it would be easier to machine the flywheel to match the crank if that is the the problem.

I think the problem is the one-way starter clutch feeding 100% of backfire torque into the starter motor. (Mine backfired, I heard the starter motor spin backwards, and that was all she wrote.)

If it takes a new crank, I just want the parts. I'd rather split the cases myself than have a flat-rate mechanic chisel them apart. Mine's at the dealer right now only because I want a warranty claim filed. I only hope it doesn't get stolen or crashed while it lives in their parking lot.
