Ok knowledgeable people.. I just bought a real ratty xl250, the older 72-74 version with the side inlet port. I'm going to to a big resto job on it and turn it into a road racing vintage motard ( if that makes sense).
There's plenty to do, but the first major thing I've found is some play in the crank. There's a few thou of end float but the worry is there is a bit of radial play too. just enough so you can feel it.
I had an XL many years ago and my vague memory is telling me that I did this before, (changed the bearings) and it made no difference and I think it turned out to be the bearing moving in the crankcase ( they are pegged in place, not an interference fit). I think it would have been better to locktite them in place.
So what's the consensus, is it normal for the crank to move a little when you grab the flywheel?
This is the first of many questions
The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.
