The throttle doesn't seem to have a way of tightening to the bars on my formula 470. Its got four bolts 2 on top, 2 on bottom. They spin and do nothing. The throttle is flopping around on my handle bars, making it annoying to ride. I also can't get into the throttle cable to reduce the free play, I don't know if there is an adjustment underneath the useless plastic that covers everything on these sleds. Anyone offer any tips here? Thanks.
