Post #159 I start with everything I did, which was basically what the people on the 16 pages before me did over two years. I did try to consolidate some of the info from earlier in that thread, and clear up some of the information. https://www.hdforums.com/forum/milwa...1-tpms-16.html
If you're interested for your Ultra Classic and if it has security on it and a GT6.5 then your replacement BCM is the same as mine (if you don't have security then yours has a different replacement BCM that I know nothing about, and you need a GT6.5 or a GTS so you can get a display there). If your has that... then to get it where you have TPMS displaying on your radio (and it will send a pop up on low pressure to it too) then a new BCM (41000341F) $180 , valve stems/sensors (42300124A) $200, probably going to need a couple rubber bushings to make the TPMS valve stems fit tight in those stock rims if they have the 11.4mm hole (I used the ones off a FOBO valve stem set I had)$10.... then its just finding a dealer to program it for you and that sometimes is the real trick. Or find a Indy with Diag4Bike to do it.
If you also want the "Dummy Light" on the tach and the front and rear pressure on the speedo's LCD screen (so you can page thru it using the trigger button and its added to the screen on the speedo with Trip a, Trip B, etc) then you'll have to switch out gauges too, but you don't have to do this if you don't want and if having it on the stereo is enough... otherwise the Speedo/Tac is $350 and the Volt & Fuel gauges are $100 each.
I looked up the BCM 41000341F on the HD website, and it says no products found. Any idea where else to look?
Ok one more question on the TPMS. Looking at one online source for the TPMS sensors, they state the following, "FITMENT: Fits '20-later Touring models (except Japan) equipped with Original Equipment or Accessory wheels that accept a TPMS sensor.". Its the last section I am wondering about.
Will my OEM cast wheels (2104 FLHTCU) accept these sensors? I know about the valve stem sizing issue, is that what they mean, or is there a "spot" for the sensor to bolt to?
There seems to be a few different styles out there, there may even be more that I am not aware of... but I believe they are all for the 8.3mm hole. My bike has the 11.4 hole, and I chose to use these (HD 42300118)... because thats what my dealer had in stock... they're made for the 8.3mm hole, like they all are... that part your wondering about is probably because of the hole size difference, all of the TPMS valve stems on HD site(s) say that.
The newer ones (I think they are newer) are slightly different, notice the shoulder on the stem (HD# 42300124A), that might require a washer (because I don't know if that shoulder will be inside the wheel) on the stem between the sensor and the fobo bushing to put pressure on the bushing, so it lays flat and helps it seal (the sealing part is me over-engineering, because you'll still have the 0-ring on the outside of the wheel under the valve stem, and thats all HD uses).
ALSO, I believe your bike came with Impeller Wheels (16" back- 17" front), like my stock wheels... If you want to see what the inside of your wheels are gonna look like, and how the sensor, bushing and everything is gonna fit... Post #159 on this thread - those are stock Impeller Wheels that just have been chromed by ***** Shiny. https://www.hdforums.com/forum/milwa...1-tpms-16.html
Lol, well, those are SHAPED like my wheels, but the similarity ends there. Those look nice, but too much upkeep for this old geezer. Thanks, the pics are "worth a thousand words" as they say.
Are"nt you suppossed to calibrate the system when you air up or check the tire pressure?
I don't know what you're referring to, I use an air gauge when adding air, not the TPMS system. The TPMS could be in "sleep" mode or lagging a bit. I know of no way to "calibrate" the TPMS system... its just reporting what the sensors tell tell it. Using a gauge when adding air gives you something to compare to I guess. Its the same way on my truck... and basically they work the same way.
