okay quick question I am running 33/69 gearing on my stock trinity 17.5. I just put on a schelle nova clutch ceramic bearings and a mip topshaft. Only problem was they only had a 84 and 66 spur for the slipper. I'm gonna test the 33/66 tomorrow but was wondering how you thought it would be? Running 35 degree timing now and temps never get over 150 with current gearing/timing
