Throttle problem

It ain't Rocket Science . . . . . . .

Interesting hypothesis. Don't know though if Johnny had the heated grips fitted. I find the heated grips to be quite effective, but for me cold weather is anything that drops below about 65 degrees.

Let's face it...the grips heat the inside of your hands and the wind chills the outside. When it's cold you either have fairings that protect your hands or you use heated gloves. It ain't "Rocket III Science" , (Please forgive me, I've been waiting quite a while to use that line....) I promise I'll never say it again.....

Now this is where people get it wrong, because it is Rocket Science.

Without my heated grips I wouldn't be able to ride the 40 miles to work in the chill comfortably. 70-80mph for 45 minutes in 45 degree weather will penetrate even good gloves after some time. My hands loose color at 65 degrees, I NEED the heat!

I've found that in temps down to about 40F, the heated grips keep my hands warm enough to be comfortable. Where I live, that's about as cold as it gets.

And yes, I actually did realize that the grips only heat the inside of my hands. Just as I realize that my heated seat only heats my ass. But thanks for the science lesson anyway.

Not to split hairs, but I believe it was a "Rocket III Science" lesson you received.

Twistgrip

I had the same poblem at about 14 months, warranty refused. When I took it to bits the plastic was very plastic but then I still remember ones made of brass!!

I see that MotionPro sells a heavy duty throttle sleeve that appears to fit the R3T. I may give that a try instead of buying another stock version. Unless any of you Rocket Scientists have a better idea.

I ended up swapping back to my stock grips. Can't believe I still had them in a box somewhere. Went on a nice ride yesterday and they seem fine.

I now think the main problem with the broken tabs on the throttle grip can be attributed to the aftermarket grips--in this case Kuryakyn. Looking at the two throttle grips together it's apparent that the Kury's are thinner plastic, while the Triumph grip tabs are much thicker plastic, almost a heavy carbon material.

I'm all for aftermarket accessories but in this instance the Triumph product was the better (stronger) one.

It doesn't appear that the Triumph brand grips have been failing like the Kury's (most if not all of the throttle cable tab failures have been Kuryakyn ones).

Now, I understand there may still be an issue with the Triumph heated grips failing, as well. I want to state that the INSTALLATION process is extremely important. The cables must be loosened while installing the new grips (instead of forcing them on with a screwdriver tip, etc.).

And there's my dos centavos.

No throttle....pretty common

That's the third one I've heard of, all R3Ts. You're certainly more resourceful than I. It was about 110 degrees when mine snapped on I10 heading to Phoenix. I pulled out my AMA card and ordered up a tow truck.

Mine was the heated grip as was the other case reported. I was hoping that the problem was unique to the heated grips, but now it sounds like the stock grips have the same problem. My new heated grip is waiting at the dealer. I'll keep the stock one I've been using till the backorder cleared in my saddlebag since it sounds like an ongoing problem.

Here is how I fixed my 08R3T and my buddies bike also: As I see I it, it is a common problem problem because of nylon parts and our need to occasionally use WOT. There is no positive stop for the throttle grip (at least not until you have gone well beyond the limits of the cable). So what I did (after my first heated grip replacement) was rig up a positive stop on the switch housing using a drilled and tapped hole and a #8 machine screw which allows a little less than 1/4 turn of the grip. I then used the cable adustment to insure that when the grip was brought to WOT that the throttle plates were also at WOT. I'm sure if some of you checked you are not even getting a true WOT.....originally mine would only register 89% on the scanner, and after adjustment I now get 98% opening read at the TPS pid.
The other alternative is to remember that once you are at WOT do not continue to twist or you WILL pull the cable end out of the chinsy nylon grip. I never had the chance to break my own...my 11year old nephew dropped in and was "feelin that need for speed" and broke mine within 30 seconds while cruising in my shop when I wasn't around. LOL

Good call on the positive stop. I don't do WOT, but I do bounce off the opposite end when shutting it down. A stop on the other end might be a need as well.
