@4949 I can't match your level of analysis, but here is a little more on that issue. A lot of it comes down to my new mechanic, Jason Metzner of "Boxe...

I suppose the wheel-side splines (they were original) weren't worn due to different metal. I think you can rivet new splines onto a wheel but Jason di...

@14724 Only the final drive side of the spines were worn, not the wheel side. The fit is plenty tight in my mechanic's opinion.

I am happy to report that I found a slightly used final drive and had it installed (along with other work). And the roll-on roll-off bucking is gone! ...

I think my splines are over 50% gone. I should get it done regardless. Re-doing the bean can felt very right but it didn't help the bucking. I'll have...

My splines are original. I've always dabbed anti-seize into them when replacing tires. I am relieved to see that there is a way to rebuild a spline dr...

The drive splines do have those steps deep inside that you mention. Having eliminated other possible causes I now feel pretty convinced that the bucki...

These rear drive teeth are, I think, very worn. Depends on what they are supposed to look like. Could this be the cause?  rear-drive-teeth.jpg

David, Right, my flat-tops don't have the smaller-diameter cylinder on top of the piston. What does that do, anyway? Are our carbs the same except ...

I've always suspected the carbs, but I've rebuilt them a couple of times with Bing's more complete kit, which includes the needle and jet. She has the...

I don't think I could have failed to install the throttle cables correctly, I've done that many times. Here is a clue worth emphasizing. The power ...

This is an update on my roll-on/roll-off bucking problem. I rebuilt my “points in a can!” Thanks to the info via Steven Rankin - I can provide the lin...

I tried looking for advance mechanism stickiness with a timing light but it's all too blurry. Don't know if that is another bike problem or a cheap ti...
