Ok so here is the question and why I ask. What gear would you run on a really short track with narrow turns with a stock predator 212 gov unhooked with a header only. I usually run a 12 tooth clutch with a 70 rear sprocket. Others run 11t clutch with 63-65 rear sprocket. Last race I went all the way down to a 64 rear sprocket with a 12T clutch and it was faster than usual! The rear gear being smaller was easier for the motor to turn taking a load off of the motor. I had tried a 68 in the past and it was weak. But making this jump down to a smaller sized sprocket worked. So it got me to thinking. What drive sprocket/rear sprocket combo are others running on a similar track. I have seen some running 19 tooth clutch with 66-70 rear sprocket online on short tracks. Would a bigger drive sprocket be better or too much for this predator motor? Just thinking outside the box. Any input is appreciated
