Once you get the parts assembled and are fitting it to the bar end, be prepared to play with it until you get it just right. It's strictly trial and error, and you'll eventually find a balance between how far in the brass expander screws in on the spindle screw, and how much tightening you do with your allen wrench.
Make sure you always keep your allen wrench with you, as it sometimes works its way loose, and needs re-tightening. I've also noticed that when I'm touring in very hot weather, it's been known to tighten up on me unexpectedly, in which case I just rotate the adjuster a bit....you'd notice it immediately, so no worries there. On balance, it works beautifully and I don't leave home without it
Well the bike had the TM installed but without the black sleeve that the bronze piece rubs against. so I ordered another one with the shim but no instructions. Is is just a matter of taking off the bar end, rolling up the grip, putting on the shims (trial and error for the number...any suggestions?), putting on the black sleeve then put on the bar end?
Exactly. I even had to trim down the black sleeve a bit to work well with my heated grips.
I don't know for sure if the TM for my Cycle Cats is the same as the Duc bars. My TM has a couple O-rings that are expanded by the allen bolt to hold it in place. I think there may have been a shim or two in there. I did find with everything torqued down, I can wiggle it in and out a bit if it needs fine adjustment.
