Hi. first time posting. Any help appreciated. I have a 93 Ninja 600R model. its kind of a rat, but its my first bike and i need it to ride. anyways. it has 23k on it. What its doing is it won't go into neutral after it warms up, also at 40 mph in 4th gear it rpm is at 7 grand, when it used to be 40 mph in 3rd at 5 grand. I just put frictions and springs in it tonight. But nothing changed. It also just started to idle at 3 grand now. This just started before I put in the frictions and springs and is still there after. Any help would be awesome. Thanks!
