Running out of time for him to try it out before he's off to his mom's for the weekend. I just ordered a 60T rear sprocket, I'm pretty sure the OEM one is 75T. OEM is 8.75" OD, the 60T is 7.25". If nothing, it will get the sprocket out the sand.
Hoping that making the gearing a lot taller will keep the thing from launching off the line so fast. We'll see.
