Then why run a 66 rear, it would need to be a 58 or 59 for 6800, in this case go to a 12 driver with a 62 and go from there.Flat kart / yellow Vegas and bjs it’s a little bigger than a bullring and I running 11 tooth but it turns way to high at like 7500 I need to be a like 6800 max and the weight or 341 and stock appearing
Keep in mind he'll only be on a 62 ish rear he should not have a momentum issue, a better sign of that would be if he needed to be on a 66 or bigger to get the 6800 rpm.If you able to maintain momentum the 12 will help but if not and your drops are huge keep the 11 on and put a 59/60 on the rear as said above. That should get you to your target rpm.
Al he's the one that states he's turning to many RPM, see his post #4 were just responding accordingly.
I was wanting to go to a 12 tooth driver on the front and I have been running the 11/66 what would be around the same gear when running a 12 tooth ???
Sorry, my mistake.Al he's the one that states he's turning to many RPM, see his post #4 were just responding accordingly.
