I dont see anything listed with Wiseco anymore so try Powroll as they list a big bore kit for the TRX90 which may be the same. They will let you know if it will work with the ATC. I had a "Big Al's" big bore pop-up high compression piston (12.5-1) in my 78 ATC90 along with a cam. This was a long time ago and Big Al's is long gone ....I think it was something like a 105cc kit and it was a mother f'er to pull that rope to start it. Ran with stock 185's though!!!
