Well dangit, didn't make it to the Rice-O-Rama after all... An epic freeway breakdown claimed the day!
Cookin' along the road, putting a little distance between me and a Civic riding my ass (what is it with kids who want to pass you on the right when you're already going 75?), and >plunk< the back of the bike drops 4" and a nasty howling commences... No wiggle like a blown tire (been there, done that, no thanks!), and it's clutch in, gentle front brake, and over to the shoulder I go. Alarming, but not freaky; it could have been much worse I guess!
Left about 500' of rubber on the freeway! The upper monoshock clevis had sheared, the shock fell back against the tire, and the suspension completely collapsed until the tire was hard against the underside of the subframe/tail-section assembly.
I lifted the bike off the tire and propped the broken clevis back into place, just so I could roll the bike to a safer/wider section of shoulder, and snapped a few pics:
When a hot tire isn't marking the territory, it sure picks up roadside debris!
The plate mount extends forward in a strip that I often kidded myself was there to prevent the tire from wearing through the fiberglass tail... Ha. Ha. Looks who's laughing now? The underside of the tail shows a little cracking along the tubes, but the subframe itself is untouched, and the aluminium plate mount took the brunt. The plate itself just barely grazed the tire. I gotta say, the little bits of burnt tire stuck everywhere lend a certain bonzai race-bike effect, no?
There's the broken clevis. Here, the shock is just sitting in place as a prop-rod.
A self-employed nephew with a truck and a cellphone is always welcome on the scene!
I was back at my shop 2 hrs after the breakdown, but the day was going by pretty fast, and my chances of making a repair and getting back on the road for the 1-1/2 hr ride to the show was slim, but I battled on...
Here's the dirty lyin' bastard cheat stock Kawasaki part that laid me low:
My disappointment is tempered by the fact that it was a stock part that broke, not any of the custom linkage parts I fabbed! I started cleaning up the clevis, with the idea of finding a solid bolt to replace the hollow stud.
I managed to get the broken bits out, and clean off the old weld, but Sunday afternoons around here don't offer much in the way of available hardware... The nut welded into the frame is M16-1.5, and a high-grade fine metric bolt just wasn't to be found.
I've orderded a Grade 12.9 M16-1.5x50 bolt from McMaster; should be in-hand Tuesday. A little more fussing, a few welded beads, and hopefully I'll be ready to make the next event on the 13th!
