Tried doing a search, almost all the TBW threads or comments are about how to lengthen the wires, the notorious green plug, and the new SE sensor. I am about to swap my bars, my 08 Road Glide is now 11 years old and 65k kilometres (40k miles) on the dial. I plan to lay down many more miles on it, already put 8k on since the end of March.

I'm curious if the TBW sensor is a wear item? Should I consider replacing it after a certain amount of time/mileage? Figure this is a good time to do such, if it needs to be done. I seem to have a bit of dead acceleration for the first 1/2" of twist now, though I think I need a better tune - that's another topic, though. Still pondering either FP3 or Dynojet.

 

That component has multiple checks back and forth. I have no idea how long it last. I doubt it is the cause of your problem, I would think you would have an error code.

You may just be outrunning the throttle in too high a gear. There is many many horror stores on here on what you are getting ready to do. From skinned wires to that plug and everything else under the sun.

Good luck.

 

Yeah, the problem isn't wear - I maybe should not have mentioned it in this thread. The lack of response currently is when first getting the rpm's going, so it is a tuner issue - again, totally separate from my initial question about TBW longevity.

 

As a general principle, if it moves, it wears. Mine went 93,000 miles before it developed a "stickiness" in its movement. When wanting to make a small input, a small effort was not enough any more, when a larger effort was made, it "broke loose" and moved too far. That happened in both directions. A new one restored smooth operation. The binding was confirmed by moving the sensor without the grip installed, the binding was still there.I believe most electrical problems can be traced to that green plug or chafed wires.

 

I recently did internally bars on my 08 RG. I think you'd be silly to not replace it while everything is apart. Get the Screamin Eagle version without the green plug and make your life easier.

 

Stopped by the dealer this morning and picked up a new sensor, let the bar swap begin.

 

This is one of those things (like the rear shock(s)) that I struggle with. I have Never in my 40+ years of pulling wrenches on Harleys Not Lubricated the Throttle Grip. In the H-D Manual, it says "DO NOT LUBRICATE THE THROTTLE GRIP". Naturally I know why, the lubricant will Kill the sensor. At 2,500 miles mine "lightly" sticks. I Would Not Advise Putting WD-40 on it. (First off I'm Not a WD-40 Person, the stuff is Crap.) I have considered a very small amount of Silicone Lube or Graphite. I'm tempted to pull mine apart and play with it. Secondly I wish H-D had made the spring tension Adjustable (+/-). If someone has a Dead Sensor, I'd be willing to pay for shipping, I'd like to see how it's made inside.

 

I can definitely feel the sensitivity difference with the new sensor, I'm glad I swapped it out.

 

Plus you can keep old one as standby spare in case of emergency .
