Ok, I got a lot done this weekend. This is where I started on Friday night.
I used an 18mm Bux Tool to install the circlips in the Wossner B piston. Its takes about 45 seconds per side, this tool is awesome!
The barrel went on without any problems, I set the ring end gap at .4mm.
Per Dogger, I preloaded power valve at .5mm.
I installed a new Honda oem head. I did not have it milled yet because I wanted to see how it runs in the stock configuration.
