My reverse lever is stuck frozen so I'd like to remove it and service it. However in order to do that, I have to remove the cowl on the ski to access the screws for the reverse lever. I think I have all the bolts that screw on the cowl off the ski including the bolt on the very front tip of the ski. I removed the handle bars and i removed the nuts that hold the fuel selector switch and chock knob. I still can't get the damn cowl off. Any other hidden bolts I should know about?
