Street triple shift linkage ball stud sheared...

Son of a....



Sheared getting on the freeway on my way home from class on Monday - tried to remedy the situation on the side of the on-ramp with zip ties but there was no way any of the smaller zip ties I had on me would withstand the force required to move the shifter, so I just bumped it into 2nd and rode the last 5 miles on the freeway home at 8K rpm.. Why do bad things always happen to motorcycles on Mondays?!

Naturally, it's only included in a $102 set that includes the shift lever and some other fiddly bits:



So I measured the threads and ordered a few 10mm M6-1.0 ball studs off eBay.. At least it happened on the last sunny day for over a week - not missing much in the way of riding right now!

make sure you lock tight the new one, it looks like the old one had backed itsself out some
and thats why it sheared off

Pile on the zip ties! I've had good luck using groups of three or four zip ties on something like that before. Of course as soon as the first one breaks, the others soon follow. Definitely seems like the OEMs know which bits are most likely to fail and package them so you can only get the ten cent bit with hundred dollar group. My rear turn signals are on short flexible rubber stalks that wear out and crack... and are only available as part of the $70 assembly.

I'm fairly certain that part was thread locked, but maybe only with blue. I had dismantled that whole apparatus when powdercoating parts last year.

It's definitely getting red thread locker this time.

I tried 3 but decided riding home in 2nd was easier - it was a pain in the ass to get at the parts behind the heel guard. Might have to stash a torx set under my seat so I can give myself better access in the future.

Got it all fixed! The 10mm 6-1.0 ball studs I got off eBay are a good fit - they're maybe 0.5mm longer in the neck (between ball & threads) but it doesn't seem to affect clearance for the shift rod.

I can't find any evidence of the original having backed out. It was really stuck in there, and there's some red threadlocker residue stuck in the threads..

My best guess is that it was damaged/bent slightly when I dropped the bike shortly after buying it in April 2014, and it simply took several years of shifting to break it.

Anyway, my Triumph is back in action! Now to fix the electrical issues on the Buell & Suzuki...
