I have not forgotten to update you guys. I was waiting for my girlfriend to come back to see if the problem still arose when someone was on the back of the bike. The good news is that the cutting out and more importantly, the throttle twisting, and then not responding at all “kind of” stopped as well.
I’m not 100% convinced that either of the problems have gone away because I only got to ride about 20 miles with her on the back thus far but with solo riding it has not happened and I have ridden a couple of hundred miles.
All I did was go to local hardware store and by 8 metal washers. I took off each of the rubber bumpers on the underside of the seat and installed 2 washer, to give the seat more lift, under each of the rubber bumpers and then re-installed the bumpers.. this seems to have done the trick so far....
BUT, what I think I found that might have been causing the throttle problem came up yesterday. I was riding along when all of a sudden the engine started revving and racing, without me twisting the throttle. Almost the exact opposite of the original problem or no power or results when twisting the throttle.
I pulled over on the street and looked at the cables to see if anything mechanical seemed “off” or observable and when I quickly revved the engine the revs came back down to normal. It was as if someone was twisting the throttle even though I wasn’t. I saw what the problem was but have no idea how to fix it.
At the end of the throttle cable, on the LHS of the bike, there is a tiny cylindrical piece that hangs off the end (in my case a little corroded) that is attached to the very end throttle cable. I think it is supposed to be housed inside of that little piece that looks like it was made for it, but mine for whatever reason is outside of the little case and just free floating. I never noticed it before and I am not sure what the functionality or purpose is? This little cylinder is getting caught in the metal piece (next to it where I think it is supposed to be housed?) when I twist the throttle this little piece gets caught/stuck on that other metal piece where it looks as if it should be housed, and therefore gets caught up holding the throttle in the open position. It is only when I rev the engine again that it falls out and the cable is released back down.
Anyone have a clue what this is supposed to look like and how it is supposed to function? I’m not sure if this is this was the cause of the original problem, twisting of the throttle and randomly no response, but it sure is the cause of the new problem of twisting the throttle and not having the engine stop revving after...
