Looking for some advise on pin weight for primary. Sled has fresh rk tek drop in kit 800, has great low end power, engages around 4500 rpm and will hit 8300 rpm easily and wants to keep the rpm climbing. Now this is running it at 6000ft and since not enough snow to hill climb yet I had to run it on the snow covered road. Should I worry about the high rpm yet or wait till we get tons of fresh and then run it under load and reasses rpm?
