Thanks from my mechanic, this will be his first sprocket change on a trike. Ran copies of this thread and gave it to him. Keep up the good work I do appreciate your DIY info. chuck

Glad you found the thread helpful, one great thing about this board is folks are willing to help. Once its complete your going to like the gearing change.
How is your milage affected?

Never changed my mileage.
DO NOT GO FOR THE DAKOTA DIGITAL CALIBRATOR !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I just had the 30T conversion done by my dealer and they installed the Dakota Digital calibrator, and if it is calibrated to the correct speed then the cruise control will not work.
The only time I use cruise control is on trips and do not have any planned in the near future so I had them set it to the correct speed because I don't want it clocking more miles than I am actually driving.
Thought I would save some money getting the Dakota Digital calibrator rather than buying a tuner, but now I'm out the price of the calibrator and still need to get a tuner so the darn thing can get set up right.
This STINKS!!
Just wanted to get this up here to prevent any one else from making the same mistake.
I definitely like the ability to take off the way it should from a stop. That was the first thing I told the wife the day we picked up the Tri Glide in Oct 08, that it was not geared right, had to give to much gas and slip the clutch on take off.

Interesting information about the calibrator, you might want to get with the manufacturer and see what they have to say about it.
According to their web site:
"2007 and later Harley models require hardwiring into stock harness, speed correction can be made up to Harley's factory margin of error, typically 3-5%≈nsp;from actual speed reading. If correction is made beyond this, it may result in the loss of the 6th gear indicator light and cruise control."
So apparently the gear change exceeds the 3-5% limit.:Shrug:

do the 2012s have a 30 or 32 tooth?
the 2012s have a 30
The MOCO figured out that the computer design was incorrect after 2 years of people telling them about the problem, so they corrected it in 2011, but those of us with the 09 & 10 models are just stuck with having to deal with the issue.
To bad the MOCO went to the wonderful computer design method to save money. Back in the old days they built it, beat the heck out of it, found the problems, corrected them and then marketed it.

I just picked up my '09 after having the 30t sprocket installed. The best way I can describe it is that it feels like my bike lost 400 lbs. It accelerates so much easier. Mine was the first change my dealership has made and I don't think he was aware of the difference between the 09's/10's and the newer models.
He said it figures though "Harley's definition of R&D is release then develop".
With the promise of 5 buck a gallon gas, I'll be commuting on this a lot.

Your dealer is right on the money when he said HD defines R&D as release then develop. They should boil in oil the folks who developed and tested these Triglides which came with the 32 tooth sprocket, the 30 tooth makes the trike what it should have been to begin with.
the 07 and 08 bikes have the same stupid 32 tooth sprocket - its a common conversion to put a tri glide sprocket on. in fact the 09 to 12 guys that want to go super fast are doing it too.
however there is a belt issue on the bikes - several ways around it, the only good ones involve modifying the swing arm and using the stock belt.
and - so far - the only good solution to the speedometer is tts... overkill for gearing but there you go.

The ThunderMax tuner will also take care of all issues with the 32T to 30T conversion.

Yeah, I'd like to find out about that one! I have a PC V purchased from Fuelmoto a couple years back.
Mine has a 10 mph speed error when checked with my gps !!1 When my speedo reads 70 I am only doing 60 mph so I adjust by running by my gps and always figure I am safe !!! But of course i always know there is the 10 mph by the speedo !!! But remember im running a 30 tooth front sprocket and a 70 rear did away with the 66 it still didn't give me the punch I wanted...I geared it exactly like my 04 ultra was and I love it it runs like a two wheeler has all the punch you need and in 6th gear it is perfect !!!

just installed a speedohealer on a vtx 1300 job went easy and the speedo now is spot on.
White Knight 30 front 70 rear. Wow what a ratio that is. lots of low end but how is the MPG and the RPM at 70 MPH?

Like I said my 04 ultra classic was geared this way and I loved the low end it had !!! I always thought it needed a 6th gear so I went this way with my trike and boy is it great !!! To answer about the RPM at 70 MPH it is turning 3,000 just about where Harleys like to be !!!! Ps. check gearing for a 04 ultra classic and you will see this is a stock setup !!! Thanks for asking Gorilla !!! Oh there is a belt change involved also... It will need the 04 belt !!! But it is worth the time and money, makes a trike into a rocket with great cruising RPM on the road !!! My MPG is 37 !!! I run 2 up almost all the time !!! And heavily loaded !!!

was really curious because my Champion came with a 70 rear and with the 32 front my trike really runs well. Maybe some day the 30 front if I have to tear into that side. Ride safe

OK, guys, I need your expert technical advice. I have a 2008 FLSTF Softtail Fatboy with a Motortrike conversion. I am preparing to rebuild the transmission to install a Baker reverse kit. I will also change the drive pulley(s) and belt. Stock has 32 & 66 tooth pulleys and a 20mm-133tooth belt. I need to know what is the best ratio for the change.
I know I'll need to go with the 30tooth front pulley. Here's my questions:
1. If I change only the front pulley (to 30tooth), what belt do I need - go down one tooth?
2. How about also changing the rear pulley? I read here about some going to a 70 tooth rear. Is that recommended? If I do that what belt will I need?
3. What is the recommended way to correct the speedo with these changes?
4. Most cost effect source for buying these parts?
I've looked through the threads, and find discussions mentioning each of these, but not a comprehensive statement of the most effective solutions.
Thanks for any and all guidance.

To install a 30 tooth with you current 66 tooth rear you would need PN 40074-07 which is the 132 tooth belt from HD. Going with the 30 tooth front will give you more bang than the 70 tooth rear with your 32 tooth front. Sourcing parts, I have bought a lot of parts from Lake Shore HD.
Correcting for speedometer has been hashed around pretty good in this thread.
I went to the 30 tooth front and the 70 rear I love it it is the same gearing had on my 04 ultra which was the stock gearing for that year !!! I always liked the way it was geared and always thought if this just had one more gear it would be perfect.. Walla changed and wow what a diff. I had to get the 04 belt for it but cant remember the number check with your local dealer and he can get it for ya...Only draw back you will have to use a speedo calibrator as mine is 10 MPH fast ....I just watch my GPS and after you ride it for a while you adjust yourself to the speed difference I didn't go with a calibrator as I didn't want the cruise issue !!!

To Msocko3 - thanks for the belt p/n. That's what I thought. Rule of thumb, change one belt tooth for every 2 teeth on the pulley(s). Now to get up my guts to tear my tranny down for the Baker Reverse kit.
Ok im getting ready to do the 30tooth conversion.
The question of the day is do I need a new belt?
2012 road glide with motor trike irs the gladiator.
I've. Heard yes and no which is it?

Doesn't yours already have the 30 tooth gear? TG's changed in '11, didn't all touring bikes change also?
Just the tg
