Dont mind at all that is the hole basics of OSS. Yes used the rings that came with the pistons from memory top gap was 0.25mm 2nd down was 0.30mm think the piston clearance was 0.05. Ran the existing shells in the crank as well but I did plastigauge them to see if they were ok. Full spec on this is b12 bottom including clutch but with a lock up clutch, 2mm base spacer, mk1 busa rods & pistons, b12 Rodger Upperton big inlet valvs flowed head, hardend rockers with gsx1100f cams, held together with APE studs & nuts, tdo4l turbo with b12 carbs set as near as dam it standard apart from 117.5 main jets. Gearing is 530 16/43 which is important to load the turbo.
