We did use a piece of glass to check stanchion parallelism. We put the sliders on (no springs, no oil) and put the axle in with spacers to emulate the wheel being in place, and tightened the triple clamps. Doing so didn't seem to introduce drag. Then we tightened the fork brace which also didn't see...

Thanx, Mal S7 (and others). I'll spend more time on the bike, trying to understand better just what the phenomenon I'm feeling is. Altho the Toaster Tan triple clamp will allow doing so, I can't push the stanchions up in the clamps more than maybe 1/2" without changing the handlebar mounts. An ...

I'm about to try a handlebar mounted master cylinder for my '76 R90S (twin ATE calipers). What size(s) of MCs seem to work best with the twin ATEs?

I have aftermarket disks that claim a higher coefficient of friction, but I don't have any actual numbers.

Thanx, guys.

Okay, here are a few more details. With the front wheel off the ground (on center stand) as 0, the sag with me onboard is 3/4". If I hold the front brake and bounce the bike up and down, the total movement is 2-1/8". After a ride hitting modest bumps, the total travel is 2-3/8". My ri...

I just finished upgrading the forks on my '76 90S with RaceTech springs and emulators (and Toaster Tan's top triple clamp). I also replaced the rear shocks with a pair that has adjustable damping (compression and rebound together) My reason for doing this was that in ordinary riding, the forks compr...

The tach needle on my '76 R90S dances around a lot. What's usually the cause? A new cable didn't help.

I suppose that means tach innards or the drive assembly in the engine.

Suggestions? Thanx, guys.

It depends on what you power with that wire. I think the ideal setup would be to use a heavy wire from the battery to the headlight shell, then use a relay to switch it. Heavy load items are the headlight and louder horns. Both need relays, in which case 14 AWG should be fine. I did a test awhile ba...

So far, I haven't found HH pads for the ATE calipers. It's reasonable that they aren't made. Perhaps one could find a large enough HH pad/backing plate and cut out the ATE profile and weld on the pack pins.

Interference is too great in my case.

I've been trying to find the best way to put conventional calipers on my R75/6 and have run into the same problem with caliper to spoke clearance. I think there are two way she: 1. Find a narrower hub, e.g. a GS hub (have to change the bearings for the axle size). 2. Run a much larger disk, probably...
