1987 BMW K100RS Throttle Tension/Throttle Lock/Cruise Control Suggestions
I just got my first bike- 1987 K100RS. In riding a little over a hundred miles, I've come to realize that I don't like how much spring tension I have to overcome to turn the throttle. It's completely stock at this point, but I'd like to do something to lessen the tension.
From what I've read, it seems like the consensus is to add something like Throttlemeister bar ends in order to lock the throttle open. My first question to those of you have used these is: how have they worked for you? Are these only ideal for situations when you are on the highway at cruising speed?
My second question would be: is there another solution that is better than the Throttlemeister bar ends? Another product that is superior? If the Throttlemeister is only usable at highway speeds, is there another product that works at more than just highway speeds?
Thirdly: is there an adjustment to be made on the bike that will lessen the spring tension of the throttle? I've read the Clymer's manual on the throttle, and I find no mention of spring tension anywhere.
As you can tell, I have absolutely no knowledge on the subject and am looking for suggestions and guidance on the matter. Anything would help! Thanks!

Sorry Ron. I see I duplicated your effort.
[QUOTE=roncooper;847409]BMW sells a throttle friction screw that mounts to the bottom of the throttle housing. Part # 32721454414. I have one on my 91 75RT and it works well.[/QUOTE]
As Ron said.
...for a cheap alternative
Here is my copy of what some companies are selling for 20 bucks. It is a piece of 12ga solid core house wire, twisted around my throttle grip. I just roll on the throttle, use my index finger to push the twisted wire down until it touches the brake lever, and 'walla', my throttle stays set. It will hold steady speed for about a minute, then vibrations start to let it creep back down. If I close the throttle manually, it just rotates on the grip.
Total cost, 99cents for the little plastic vacuum cap on the end.
