Well I fixed everything. Sanded the outside of the clips and used a dental tool to dig out the center of the clip slots.. clips seat in nice now and are hard to spin.
Saw why the pin was a lil loose, one side of the casting is missing a bit of alu where the pin goes thru inside the piston so it doesn’t have as much pin bore as the other side. Nbd, it’ll run for awhile.
Just gotta finish the pipe tomorrow and I get to test the bolt on mount and the new engine setup. I also attempted to bore a 21mm OKO into a 26mm OKO. It looks promising after cleaning and blowing it out and putting it all back together. We’ll see if it works.
