I recieved a phone call from him the day the banshee blew up. I told him to call me as soon as he figured out what happened. I got a few texts from him and that was the extent of it. I told him about everything wrong with the bike. I.E. the broken part of the frame, the clutches not working properly and he just keept saying he didnt care. Again he sent me progress pictures of the bike and everything. The compression test was 100% perfect in both cylinders. It started right up and ideled for them in the parking lot. What more do you want? As far as the pistons go I am still 99.9 % sure that I had .30 over pistons it in.
