They haven't exploded. I don't ever go easy on them or anything, and I ride the dumb thing so I feel like they might last, bike revs way out before shifting like I think at 27x22 it probably does low 20's in first, next warm day I'll probably pull the side cover and see if they are still in one piece and check for cracks, I'd be willing to bet the pad material adhesion gives up the ghost before the actual shoes break.
That's first gear, I mean it engages higher than before it was lightened, I'm still looking for higher engagement, but I can't see where I would loose more material on the shoes, so I guess I'll wait for stiffer springs, or for some kind of ktm clutch setup to fall into my lap.I could also use a lighter flywheel.
I weigh 250lbs and I don't normally ride with a bunch of fast bikes or anything, but the only thing that is quicker of the line is my man mickrkittens' moby, but mick only weighs like a buck twenty or something.
Casting them would be funny, because all I did was eye ball them on a drill press.
if anyone wants to talk clutches or whatever, feel free to get at me.
