The Evolving EVO (Brakes)
#13
Just let me know if you guys need more pics.. I've accepted the JB Weld as the fix for now. I've run 30k or so on it and its one of the best mod's I've made.. If I have to chip the epoxy off every time I change the tire, it adds about a beer to the job... I'm fine with that.. It was the simplest solution I was able to find..
Greg, I was wondering, in your opinion, why do you think the speedo drive is failing?
Stock early( 3/4) drives are not prone to failure far as I know.
Do you think maybe the spacing/spacers are wrong allowing either wobble or the drive being cocked between fork leg and wheel?
Also have you got a part number for the longer drive cable?
Thanks

Hey John,
The spacing actually came out great as far as the axle and wheel was concerned. The issue is the stamped steel drive tang. It wobbles as the wheel rotates, because there is only one tab in contact with the wheel/rotor.. I think its really just a shitty design that could benefit from another tab 180* from the existing one.. but because it seems to work fine in the original applications, I'm probably deflecting from my ability to find a real fix..
If you were to find the right foam spacer to provide proper support for that stamped steel ring, keeping it from wobbling, the tab would probably survive... I've kind of put it to the back burner and quit searching for a good remedy.. next tire, I'm sure I'll revisit.. hope that helps you visualize it, I can get some pics pointing it out tomorrow or this weekend day if you need..

I'm still on the original speedo drive, at least 30k since the brake/wheel upgrade,
the tab is loose in the slot, the slot is about 3/32" wider than the tab, and twice as the tab thickness,
should not have any bind on the stamped piece, it just floats, I can grab the tab and wiggle it back and forth,
no foam washer here

Anyone know what the work-around is for Mac? I'd sure like to look at HGMs pics!
Never mind........ I found a Safari extension that enlarges thumbnails when hovering the cursor over them!

Did you machine the drive, or add a shim?
I gotta ask around to find a machine shop that is biker friendly.
