Throttle stop?

[Red_Hen]

Anyone using this?  If so, does it work well?

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?

[montmil]

Both my R65s had the "locking bolt" fitted when I bought the bikes.

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?

[Bob_Roller]

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.
