Anyone using this? If so, does it work well?
26 LOCKING BOLT 1 09/1980 32721230874 $12.61
-
It's a friction lock for the throttle, kinda like a cruise control .
I only use it when I'm on rural Interstate highways .

Ken,
I have them on both my bikes. As Bob mentioned; when touring I'll use it to lessen the return pressure on the throttle grip to limit hand/arm fatigue. It's a simple thumb screw with spring that applies friction to the throttle grip tube. I call it a thumb screw but never been able to operate it with just the thumb, it'll take a thumb and finger to operate. I normally set it where I want it before venturing on the bike since it's a little cumbersome to deal with on the fly. Not sure if you could really call it a cruise control but maybe a cruise aid. I wouldn't recommend turning it to the point of locking the throttle - since it may become a safety factor. It screws into a threaded bore at the bottom of your perch most likely covered with a clear plastic plug. Just remove the plug and screw the device in to the desired tension.
I've become attached to them on both my bikes.

They serve the function to hold the engine at a specific rpm during tuning operations.
I keep the screw just snug enough to reduce the wrist's workload. Being doing this for years so it's just second nature to roll the throttle closed when required.
-
Thanks guys - I know what it is - just wondering if you use them - I'm gonna order one as the throttle on this bike has a lot of tension! I have one on m K75s - it's a latch and I use it all the time!
Did you buy yours from BMW?
-
Both my R65s had the "locking bolt" fitted when I bought the bikes.
;D Poor Michael. Don'tcha know you need to use both thumbs.
-
I'm in the minority on this issue(I'm used to it) I DO NOT like throttle stop screws. Used it a couple of times and pitched it. For what ever you gained keeping the throttle open you lose when you try and shut the thing down.
There are very simple devices out there and cheap too that accomplish the same thing and do it better. http://www.aerostich.com/go-cruisetm-throttle-control-1.html There are videos on youtube that shows the device in action, it's a no brainer . Throttle screw -3 go cruise +10
As always YMMV and usually does LOL
-
I don't use mine except for warming up the bike while putting on the gear, or whatever. Don't have much of a problem holding the throttle open for hours on end - guess all that guitar playing is paying off!
If the tension gets to you, I've heard softer springs are available - the stock heavy ones are supposedly much stronger than needed.

Springs on the carbs?

Ken,
Throttle return springs. You can purchase lighter return springs. Here's a link to some if you're interested.

As you can see there's many different opinions and uses for the screw. I find many convenient uses for mine.

Thanks, Mike!
I'll be taking a 2-3 hour ride (each way) on "Tina" to a friends place in Shell Lake WI - he's restored a J4 Piper Cub and also rides BMW's.
The throttle stop will be a nice accessory as the springs on mine are very tight.
Did you install the lighter springs? If so, which ones.
-
Mike - been meaning t ask - your avatar - what is it a picture of?
-
It's a picture of an intake or exhaust port of his R65 .

Looked like the picture they sent me home with after my Colonoscopy

Yes, after I had the heads rebuilt. Can't remember if it's the intake or exhaust.
Ken, I have the stock return springs on my R65 and R100. I don't fiddle with the throttle screw much unless on an extended ride. Personally, it just makes things a little more comfortable for me with a little friction on the throttle tension taking some effort away from my wrist on long distances if on the interstate.
Personal preference.

For me - sore tendons!
-
I understand. Especially after the surgical repair of my right distal bicep tendon rupture trying to catch my fully loaded /7 bike from falling with one hand. That was a humbling experience - what an idiot I am.
If such a small part can add to your comfort and riding pleasure I feel it's worth it.

check out EZ pull throttle return springs, 5 minutes install for both carbs. I put them on both my airheads, I really noticed the difference....

What's the Bing # for our carbs?
Mine is '82 R65ls

Tune up screw. Works very well for balancing carbs the old way.

64/32/325 & 326 is one pair of numbers for a US 82- R65.
Type 64/Size 32mm/Model No left & right.
There may be others as I think the number changed with different jetting between UK and US models.
Take a look here for more details

Thanks, Barry
I ordered the EZ Springs today and needed the right carb number.
Will report back how they work after I receive & install & ride.
-
I use mine rarely, but do use it. I find it hard to get properly set and that's more distraction than I need. I am going to try those lighter springs though.
-
I use one of these...
-
Got my throttle stop today - yay!
Had to use a hacksaw to cut down the threads on the mirror stem - a very tight, precision fit and screw!
Do I have to worry about the screw working it's way out when riding? It doesn't take much screwing in before the throttle stops springing shut. Was thinking of putting a little teflon tape but interested in your experiences!
Got the power plate today for my aux power port - now (according to Mr. Roller) there are only 5 left at the BMW warehouse! It's a nice piece for $6.
