Sunny here in the Pacific NW, 65 degrees and I'm running Skyline Blvd and having a blast. I go to down shift from 3rd to 2nd and there's nothing there. I mean my toe just drops into thin air. I look down and the shift pedal and linkage are dragging / flapping around under the bike.
Looks like the post that held the the shift lever into the rear set just backed out (the thread path is clear, no broken off pieces in the rear set)? It swung around and scuffed up the stator cover (now I know where those mysterious scuffs came from, this has happened to this bike before I owned it) WTF? I just checked and lubed this last weekend?
Had the wife bring me a box of leftover old / used bolts and washers, my sockets, pliers and cable ties (just in case) and limped her home Macgyver style. It even ran through the gears just fine with a rusty old bolt and cable ties holding it together (Macgyver would be proud!)
My shifter pivot bolt backed out and disappeared on my ride home from buying my (otherwise in-top-condition) 919. Ended up doing the last five miles by reaching down to the transmission and shifting with my hand. I made up some bushings at work, and converted the mount to a through-bolt with a lock nut.
Happened to me years ago while 2000 miles from home. My ride partner behind me got me to stop right away. I walked back on the highway about a quarter mile and found it. Believe it or not.
The only other bolt that is known to back out is the clutch pivot bolt.
3rd is easier, if you ever get stuck in that predicament again .
Uh, check the clutch perch bolt, the one that has a nylon nut on the bottom - sometimes it likes to come loose, as we know from Andrew's experience at the last track day.
A little loctite just on that nut helps. Sometimes the bolts on the bar ends. Anything where you can feel a lot of vibration.
And I grew up watching MacGyver! I seriously attribute my jack-of-all trades attitude to that guy!
I knew you were another child of the 80's Google!
Me too! And learning from my dad and the circle of "old guys" I know. Duct tape, bailing wire, cable ties, steel wool and locltite have been life savers! There's always a way to patch it together and get it home.
