More miscellaneous cleaning and sub-assembly.

Cleaned and polished the brake pedal and the clamp that goes on the opposite end of the brake shaft. Cleaned the rubber cups and washers that go on the shaft as well. Slipped everything together.




Cleaned the starter button and installed it into the bracket.


Cleaned all of the pieces to the steering damper assembly. Sprayed the knob with S100 Engine Brightener to make it black again. Replaced the steering damper with a new one. 


Working on the swingarm next.


New swingarm pivot bearings and seals.



New carrier bearing...


...u-joint...

...boot and clamp. 


All finished and ready to be installed.


Cleaned the "mudguards". Haven't polished the stainless any, not sure I'll need to. 


These knobs aren't original, but do the job and are 1/3rd the cost of the o.e. type reproductions. 


Axles. The front one cleaned up very well, the rear one - not so much. 


It really needs to be rechromed.


The washers look good, the nuts will be replaced with stainless steel ones. 


Disassembled the rear shocks. The dampers themselves are in good condition - no leaks and nice damping. The retainers and adjusters will clean up well, the springs? I'm soaking them in EvapoRust to see if that makes any difference. 


I've had a pair of NOS springs for years and hoped that maybe they would fit. Close but no cigar.  :sad: Not sure what the springs fit.

After soaking overnight in the EvapoRust, all of the rust is gone and the springs look 100% better!




Stripped the paint from the dampers.




Cleaned the adjusters and retainers.




Quickie polish has them looking better.




Painted the dampers.




To finish out the evening, I disassembled and cleaned the taillight. The bracket needs to be painted, but the taillight is ready to go back together.

Rod bearings are showing some wear, but not as much as I expected, really.

Rear main wear.

Crankshaft looks better than expected, but again, it will need to be measured carefully.

Front main bearing wear.

Charlie:  Maybe I missed it, but how did the rod and main bearings measure out? Did you replace them (sorry if that's a dumb question)? I have only taken a similar engine apart once, and the photos you showed looked more alarming to me than you indicated. How much of the wear do you think could be attributed to the chrome flaking off the cylinders?

Main bearings had very minimal wear (consistent with the mileage) and were reused, rod bearings were replaced. Most of what you see in the photos was superficial or was made worse looking by the camera flash. There was no evidence of any embedded chrome flakes.
