The difficulty wouldn't be because of the non-OE brand but because of the non-OE size.  Shops are only going to stock or be familiar with ready availability for the standard sizes.  Make a change to something outside the norm and we can't expect the shops to be ready for it.

Oh, sorry I get it- 139T harder to find and not stocked by the dealers.

I am definitely looking at doing this mod, along with the SE compensator-how many have been able to get the dealer to cover the compensator under warranty? Maybe just a couple catch phrases put into a complaint about chattering?  

Sounds to me if HD was an auto manufacturer, this would have been a recall....they (auto mfg's) recall everything that they even SUSPECT could be an issue- not sure how the Moco can get away with being different.

Too bad harley doesnt carry  a emergency repair belt for 07 and up. The older one they carry is  # 40112-97 and  is for 97 to 06 139 tooth emergency belt  but it's not 1 in wide   I thought of trying to make one like the old temp. repair belt, I was going look if i could  to drill quite a few teeth and tap  or try to use self tapping allen head screws like the factory one, make it tapered  by cutting it  "V" shaped end to fit like the old style. Dont know if it would work . I'm still trying to figure the taper  angles,  hole sizes  It may  work may not,  But i to feel traveling around with a odd length is kinda  not good especially across country

That might be a reason to just go for the 31T pulley, since the stock belt will work, although not recommended- it should get you by in a pinch.

I'm sure I want to do this mod, along with the SE compensator, but now I just have to decide on the 30T or 31T- I just don't want to lose that relaxing purr on the highway in sixth feeling too much.

[timtoolman]

the same relaxing purrrr is still there, just  a lot more responsive

     I second that. Why waste the time and same expense for little increase in performance. I went to the 30 tooth and love the extra driveability I got. I can let out the
     clutch in first with out using throttle when in tight areas and not worry about slipping clutch.   Chilly

Mine is at the shop having the 30T done right now! I'm using Harleys pulley and Drags belt. It'll be nice starting out in 1st gear again.

[timtoolman]

How did you start out before?

[2018_FLTRXSE]

OK... I'm confused... I'm doing 74 (according to the speedo) at 3K.... (corrected with TTS)

yet the OP says 80 at 3K... ? same bike, same gear ratio.. the only thing I see a potential problem is the correction factor in the software... the correct number is here someplace....

Ha Ha. It obviously felt more like 2nd. Picked it up today. Steve and all you folks on here are right. What a difference! Haven't had time to readjust the speedo yet, but I'm happy with the result.

"yet the OP says 80 at 3K... ?"

 

From the original post:

  RPM...  80mph-3000rpm
             90mph-3400rpm
            100mph-3800rpm

I'm doing 74MPH (speedo) at 3K

[rayson56]

Haven't done mine yet, but when I asked Steve George about the speedo reprogam with 30T and TTS, he said to ad 50 points to the recalculated value to get a good base. Then check it with a good GPS for accuracy. FWIW

I don't have an issue with 6th gear- I don't lug it in sixth, because I'll just keep it in fifth until it's ready to be kicked up into sixth. Maybe it's an issue if you're always on a road with a 55-60 mph limit- maybe that's a speed that some consider to be in between fifth and sixth gear. When I'm on the highway, it's 70-75 mph, so being at 2600 or whatever it's at is fine with me.
I do agree with the take off in first gear, so maybe the 31T will help that enough. I also want to feel some more torque and acceleration, and that's my other reason for considering the mod- well, also for the reason of having the upgraded SE compensator.
I came from a 5 speed Yamaha that was buzzy on the highway, and I want to be sure I won't end up with the same- I really like the smoothness of this bike on the highway at 70-75 mph.

I'll bet the reason is that 2009_FLTRSEI3 has already made his speedo correction with his TTS (so it is accurate), whereas all of us have the factory speedos which are optimistic. So 74 real speed for him is 80 displayed speed for us.

Possibly... I had originally set the correction factor from original incorrectly.... I used tire size from the CUSE (it was the default size in the drop down menu and I missed it)

The correction factor is posted elsewhere in this thread. I havent tried the GPS on my phone to validate speed... 

Though I did have some clear road today so I rolled into it in 6th...

3K = ~74 MPH
3.5K = ~86 MPH

Will look for a little more road with space to try 4K....  98 MPH?
