Linkage mount on the swingarm was tricky. Got the sleeve out using this tool

But the bearings had to be pressed out.. took a bit of care and force to not damage the swingarm. Had the same problem getting the pivot bearings out.

Back to the engine for a post..

The top end looked OK except for a broken post on the LH exhaust valve. This led to a big search for a replacement, or maybe for a repair. I posted a thread on VitalMX's Old School forum and got some help. The VitalMX thread is worth reading.. lots of options listed there for getting a power valve for these old bikes (the power valves are NLA and nearly impossible to find as NOS). Here's that thread: http://www.vitalmx.com/forums/Old-Schoo ... ve,1270119

Here's the top end with exhaust valves removed

Sent my cylinder & head off to PowerSeal a couple weeks ago and hope to have it back soon.

A couple months ago I got the frame stripped and ready for some repair & powder coat

Had a local machine shop fix the right side footpeg mount (which isn't replaceable like the left side)

I regret not having them fix the brake pivot mount.. completely overlooked that (after powder coating).

Dropped frame off at PCC in Atlanta

Easier than expected!

1/4" threaded rod, had to grind it down a little then notch with a hand file. I used a hacksaw to get a little reverse bite on the edge.

Used a tiny allen wrench to put in the bearing inner race behind the puller rod, to keep it snug.
