1975 R90 Idle Speed

It would be a bit difficult to do that elegant full lock U turn, with your feet off the ground, if you suddenly go onto full revs!

I would really sort out your cable routing/lengths as a safety issue.

Its more like bumping up to a fast idle. As a geocacher, I make U-Turns all the time - and I never put my feet down, that would be poor form.

Besides, here in Texas, there's all that cow poop on the road, and all.

The dual stable just means that it will idle slow and stay there if it is already running slow. If its running fast, it won't slow down until I do something to slow it down like fingering the kill switch or slipping the clutch.

That is exactly what Duane referred to as "classic symptoms for weak advance springs." It is very weird for it to be doing that with an electronic advance. I would definitely try running it on the points just to see. Maybe something has gone wrong with the electronic advance.

Interesting to get in on this discussion. I've been pondering installing some slightly WIDER but about the same flatness bars on MY R100s to have a bit more leverage (I'm feeling my age!) and clearance from the tank bag.
Cable length is a concern...I'm using normal S-bars with bar-backs now and the cables seem to be about at the end of their useful length. I'd sure like another inch or so on each bar end, but think it'll involve a big cable-change job.
Guess I better get on the weight bench!!

Jean, I've done that mod on my '77S bike. I used K&N "Superbike" bars, lopping about 1" from each end. That gave me bars that are about 1 inch taller with about 2" more width. It made a lot of difference for me--more than I would have thought.

I wouldn't use the K&N bars again though because they are 7/8" diameter rather than 22mm. (I was younger and foolisher then, but I got away with it.) I have seen some aluminum "superbike" bars, made in Italy as I recall. That's what I plan to use if the need ever comes up again.

There's quite a few Ducati Monster bars that have a nice bend, both in steel and in aluminum. They are 22mm, but I don't know if there are any of the aluminum ones that are not the fat-in-the-middle type.

I have some 22mm bars that give me the same pull-back as using the bar-backs (which will go away), and are wider...I think they came off a /5 or /2...I'll give it a try this winter when it's too nasty to ride.
