I’ve been really lucky I think. Parts are very expensive here in Australia. I purchased a full engine rebuild kit out of the States for the price that I would have paid for pistons and rings here in Australia.
I’ve been reading anywhere from 15-11.5cc’s for the Commando Pistons. I read a guy cc’d a set and they came in at 11.5 but just wanted to be certain.
I like the looks of these pistons but I would think it might be a good idea to smooth the tops to prevent detonation. Maybe @yellow rose, or @rumblefish360 can chime in with a recommendation. What say you @RustyRatRod, or @krazykuda ?
