Haven't been on here for a while, cleaning up after Hurricane Michael and haven't used the bike since then. My problem now is that there is a lot of resistance in twisting the throttle back and forth and it doesn't return back to idle or slow speed when you release the grip from a faster setting. The spring in the carb throttle control is not the problem, that end works fine as I've had the carb off to inspect and clean it. It seems from all the incredible amount of sustained moisture down here recently that it feels like there could be some rust or corrosion inside the cables and sheaths, so I'm wondering how to access this or disconnect them from the twist grip. I would like to try and drip some PB Blaster or oil into the cables to try and loosen them up, or I have to replace them and that means having the same access to the top ends. So I need to know how to get this apart. Thanks.
