But the MAIN THING IS ... the Cramp Buster does not solve the problem of a TOO STIFF return spring and still requires more force than it should. You can't do fine motor control on the throttle using the Buster. The palm of your hand is not good for accurate throttle control. Fine for steady state droning ... but nothing more, IMO.
Maybe I'm the exception here. I use the extra-wide CrampBuster on all three bikes. Having come from ATVs and snowmobiles, both of which used thumb throttles, I had a lot of trouble adapting to the motorcycle twist-throttle. I found my right hand very quickly becoming numb.

So, somebody suggested the CrampBuster. The one I got was the wide one, since it's all they had. I put it on and set it up the "intended" way, to be used by the palm. Wow, that doesn't work for me at all. So I repositioned it. I moved it all the way to the left of the grip, and rotated it downward to about 45 degrees from level.

What I do now is I use my thumb on the CrampBuster, effectively making it a thumb throttle. The result is I dont have to squeeze the grip so much. I keep a very relaxed grip and can modulate the throttle very well, even in slow, technical situations. It's taken some time to develop the muscle memory and fine control, but it works very well for me.

Agree the Throttlemiester while riding offroad can launch you into the weeds !
My buddy uses one on his DR offroad and I don't know how he does it !

What I like about it is it's adjustable to any position. Even completely out of the way. No modifications, so it comes right off at any time or goes right back on. And it cost nearly zero.

I doubt many get more than 50 MPG with a TM40. (sorry, not sure of the kms per liter conversion) I think perhaps you never had your BST Carb set up correctly. With proper breathing and jetting the BST allows very good power and still delivers good MPG.

True about the mid range gap ... the TM40 is better there. My main complaint with the TM40 is the very stiff throttle action. Very tiring on a long day ... especially riding off road. I hate stiff throttles.
Yep, my BST settings were quite rich when it was last time in bike. With 45 idle and 145 main jets, CO% in idle speed 1500rpm measured was 3,5-4%...snorkel tooked off. But still not very good cold starter when 0 celcius or less, now today example is -10 degrees celsius and started very easily without any extrahelps.


Stock back up spring is very heavy in TM, but theres 3 points turningcam where it can set. Most lightest point with electric heated grips work for me. Heated KOSO made grips are very chunky, thats why its lighter turn gas too...

But thinner would be better otherwise, especially when drive standing easier keep on properly. In RM 250 i have most thinnest Renthal grips.

Agree. I owned one for about an hour. It was fine when just cruising along on the highway but as soon as I hit the tight twisties, I kept bumping it (and adding throttle!) whenever I reached for the front brake. I threw the damn thing in the ditch before it killed me.

I have been using THROTTLE ROCKER (not sure if still in production, bought 6 the last time I saw a ad for them, on all my bikes for the past 15 (well over 200K miles) or so years on all my bikes except my KTM 200 EXC single track bike and GSXR 600 trackday bike.

As far as anything other than single track I have never had any problems with throttle action. On sand roads/dirt or gravel roads no problems at all. Many of my riding days are 12 to 16 hours long and I really enjoy the ease of arm strain. One has been installed on my DR650 since the first day .

But will ad that one of my favorite riding buddies hate them.

I have one on my streetbike. My handguards kind of get in the way on the DR, but I have throttle-locks on both bikes for long stretches of slab.

The Throttlemeister is a tool the replaces the bar end and is engaged by rolling it backwards. Not the same as a cramp buster. I have one on my C14, and at times I use a cramp buster type on the DR for those highway cruises.

I never hit better than 46-48 with the BST carb, so 45 with the TM40 isn't really going to be much of a hit. I could see the throttle getting tiring on longer trips, but I think it feels like you're grabbing something substantial when you gun it.

I put one on for my Blue Ridge Parkway ride and have not wanted to take it off.

It slips on over the grip and you position it so the heel of your palm presses it down. That way you can relax your grip and still keep the throttle open. I don't even notice it while riding tough offroad stuff. Got it on sale for half that price. a bargain if you ask me.
Are you using the CB2 - 1 3/8" And Smaller Diameter Grips or Larger Diameter Grips?? I was going to get one of these ages ago but since I have Oxford Grips, not sure which size to get??

thanks

Great idea! I never thought of that one! Only time I rode snow machines was in the Antarctic! (19 months there) I like the thumb throttle, adapted quickly to it.

The small one. I just measured my offroad grips at 1.25 in.
