I was coasting to a stop yesterday, clicking through the gears, when all of a sudden I couldn't feel the shifter any more. Once I'd gotten myself out of traffic I looked down, and the shifter was just dangling off the linkage. Basically the shifter bolt had backed out, so 2 minutes and the trusty Kawi tool kit later and I was on my way again, but it was definitely unsettling.
It looks like the bolt took one half thread of aluminum with it when it went out. Is there anything I should do except torque the bolt down again with some Loctite?
When I bought the bike 3 months ago it was converted from GP shift back to stock. Would the mechanic have fucked up so badly that the bolt would back out just 600 miles later?
Has this happened to anyone else? I feel lucky I was going slow and not doing anything exciting, but I can imagine this could be dangerous at other times.
He probably just didn't use loctite, when I rebuilt my bike from the frame up I torqued everything down nice and tight. Two weeks later when I had a coolant leak and stripped the bike down again I found 4 bolts had backed out completely and were rattling around near the battery, and I'd lost one of the two bolts holding the radiator in. Vibration sucks.
I will think it's common to lose some screws, even if the screws were untouched from factory. The first service actually mentions torque checking on all the screws and parts.
I lost two on mine in just 6 months, given that I have done more than 10 track days on it. One that secures the lower fairing, another one on my rear passenger footpeg. My friend lost one of the left footrest, causing him unable to shift.
Proper torque helps, and some screws just need a drop of loctite or so. I wouldn't put loctite on all the screws though.
