Not a bad job if you like wrenching. Right inside of the back cover of trans if it's the spring.
Any spring to the shifter? Does it just flop up & down?
It goes back to "home" position.
I was the one riding the bike. At first it wouldn't shift into 1st, then the next little town we came through it wouldn't shift past 3rd, and finally by Stronghurst Ill. it wouldn't downshift at all. Lever moves like it should just no feel of a gear change.
While it was a little hot out it was a nice day for a ride. I messed that up by dumping the bike in R&K Cycle's driveway. Downhill, loose gravel, right hand turn, at 5mph. Only damage was to my pride. Then we gnawed on a ridiculously sized tenderloin at Spoonies. Then the shifting fun started. No joke, I can mess up a crowbar in a sand pile.
