so i started noticing this on my last 2 trips to the dunes. when im goin along in 4th and get on it, it doesnt accelarate smooth. it acts like the gears are grinding every like 2 seconds. i installed a new tension spring. its the spring that holds this little roller in its spot. im pretty good friends with the local dealership owner here and he said it would be lucky if this was the problem and that spring was just wore out, and it was popping in and out of gear real quick, but that wasnt the problem. if my 4th gear is out, im not sure what im gonna do.
