My 01 fatboy is going to a local mechanic tomorrow for new cams, bearings and gear drive. He told me that he is putting in Andrews tw31s cams. I was just looking at the Andrews parts catalog online and that particular cam is under "tc88 chain drive cams". Will this cam work for the gear drive setup? If I'm reading it right, I should be using the 31g that's listed under "gear drive cams".
