Hi, Folks,
I don't want to rain on your parade, guys, but I went down a similar track a few years ago when I re-built my 100TMX. It still had a couple of perished rubber wiring straps attached. I bought some new ones to replace these and added some others in what seemed likely places attaching wiring harnesses to the frame. It looked good when finished, but within two years, all the new straps had perished again. A couple I had left over in the packet still appeared OK, but it seems that once old rubber straps are placed under stress, they have a short life. I ended up using black ty-raps instead for out-if sight wiring straps. For the visible handlebar wiring (front stop switch harness), I used BS wire clamp (part no 1689-5000) intended for the holding choke and throttle cables together just above the carbs on the 90/100 models. I clipped this around the stop switch harness and front brake cable.
