I'm going through a bout of tendentious in my elbow and the bike would work better for me if the throttle return spring required less effort. I already have a throttle friction grip on the bar end but less spring would help.

Maybe somebody can explain the throttle cable system. I only see a single cable, which is kind of surprising. I thought all bikes had dual cable systems for safety reasons. One cable to pull the throttle open, the other to pull it closed. Maybe that's why my previous bikes had lighter throttles - they had a mechanical closing system and didn't depend exclusively on a spring.

Hi, Dale,

This doesn't directly answer your question, but one thing that might help would be increasing the diameter of the handgrip a little with an aftermarket foam sleeve. (There have been some threads about this in the past.)

It will increase the diameter a bit, reducing the force needed to apply the same torque to the grip; it will probably also wind up with a "grippier" surface, reducing required hand pressure to keep the grip from slipping.

Hope this helps,

+1 on the foam grip.

I've also added a Throttle Rocker so the heel of my hand holds the throttle open, not the grip of my fingers. Works for me and I don't have to guess how to modify the product of the inscrutable and unassailable wisdom of German engineers.

another version without a velcro strap allows on-the-move adjustment:

Takes a bit of adjustment to find the sweet spot, but then it works simply and, at $10 is probably the cheapest farkle you'll buy.

+1 on the Throttle Rocker.

I used to get a sore right forearm on long trips from holding the throttle open. With the Rocker, all day rides are no problem.

Kaoko cruise system - you can easily adjust the throttle sensitivity on the fly by increasing / decreasing tension on the grip.

Bill,

I got the Kaoko - and can't say I'm too impressed. It has to be continually adjusted if I turn the heated grips on/off. I know this was a problem with Throttlemeister and Bob's - I was hoping Kaoko had a better answer. My $0.20 "O" ring behind the bar-end weight actually worked more consistantly.. it seems the expansion of the throttle grip tube didn't change the drag anywhere near as much with changes in temperature. Perhaps not a problem once the weather gets warm enough not to use the heated grips - but I've been known to use them in mid-summer on a rainy day..

I'm considering adding a thin rubber bit between the Kaoko and the grip to see if that works like the O ring did. Gotta get to that job..

Don,

Tempted to say TADT but in fact my Kaoko only does this when the grub screw is outta whack. Trouble is that I've forgotten to fix it before my last few rides and remember ONLY when I simultaneously reaise the right allan key is still at home ... actually, that's more like the past 5,000km.

My first 15,000 km with it was poifickt - and I could use it to "dail up" the amount of throttle spring I wanted at the time ...

You are right that when it is outta whack it's no better than any other. Also tend to wind itself "on" - the Wunderlich one I had on my R1150RS never did that (but then, it never kept tension either)

I'm not trying to hijack this thread, but I'm also curious about the design of the throttle. I noticed on my last trip, that after I got rained on, that I had no spring return whatsoever. It was actually kind of nice. Instant cruise-control when desired. Then once the rain had stopped for a while, and air-dried, the grip was back to normal. Any insight? I don't know how the mechanics of it works. More importantly, is this a sign of a possible underlying safety issue? I'd start a new thread, but this seems pretty closely related, as the responses would probably shed light on how to adjust the return spring tension.

I am very happy with my Kaoko.

No particular insight, but this doesn't sound right and I would call it a safety issue as there's nothing obvious that should be causing this to happen.

I ride in the rain, well, pretty much every time it rains around here, and have been through some major downpours in the R1200R. As there's no indoor parking at work, my bike has often sat through a day of rain. I've never had anything like this happen, either during a ride through, or after a day of sitting in, the rain.

Good roads,
