Is there any change in gas mileage when you do this conversion?
 

[moscooter]

 
I've not yet been able to tell any real difference.  In fact,  I have not yet had someone with a "stock" bike or car ride along side and help me validate how close (or far off) my speedo is (which would effect the odometer as well).

So far,  I'm not thinkin' there is that much of an error in the speedo...........but will verify that pretty soon.

Meantime,  I would speculate that the milage (given the type of riding you're doing, just might be better......not worse).  Less down shifting and better usage (wider range) of both 5th and 6th gear.  For example,  if your's gets worse,  and you used to get 45 MPG,  the ratio change is 6.6% so worst case,  would be your milage could drop by a little less than 3 MPG.  BFD

I wonder if the 31T would be better for relaxed highway cruising at 70-75 mph? Wonder how much more felt power it would be- only going down one tooth...might not make enough difference to be worth all that cost and effort....I dunno, maybe better going for the 30T, as long as it doesn't make the bike feel like it's only a 5 speed.

Btw, Phats Performance Parts has the Andrews 30T for $115.00 and free shipping. Also pondering if it's better to go with the Andrews for a few bucks more since it is the proper 1" version, or go with the HD Tri-Glide pulley, since you all say the belt centers itself on this wider pulley.

Here is some info from Baker's website:
 
30-tooth or 31-tooth h-d® 2006-up cruise drive™ pulleys

Get more oomph from a throttle-wick on your 2007 stock Harley-Davidson FL. Our 30-Tooth or 31-Tooth transmission pulleys effectively ‘gear down’ the bike to optimize the performance in two major ways.

First, you’ll get more torque and power from the take-off gears. This remedies the common criticism of the new bikes being a little sluggish off the line for some riders.

Second, you can utilize the 6th gear at a slower, more reasonable highway speed for a more comfortable RPM. These pulleys bring the cruising gears down a notch for finessing your ride.

Performance details are as follow:

Increase Rear Wheel Torque (30T- 7% Increase / 31T- 3% Increase)
Cruising RPM 6th gear (75MPH) 30T @ 2830 / 31T @ 2756 No more lugging the motor in 6th gear at lower cruising speeds (60-70 MPH)
 

Answers my question- only 74 RPM difference at 75 mph between the 30T and the 31T

 You can run the Tri-Glide pulley and get a belt for a Buell Blast which is a 139 tooth 1" belt. Brother called
 Dealer and belt was around 90 dollars.   Chilly

Is the  Buell blast belt heavy enough for a bigger v twinn,??   Im asking because i just replaced  the first 139t belt  with another   bdl falcon one   it was 200.00, mustve been that last big wheelie that stripped the teeth for about 1 ft,

Whats the part number on the Buell Belt ?

Woo Hoo! Out for a ride today and heard a loud clunk coming from the isolator sprocket. Normally that would pi$$ me off to no end. Looks like I'm going to have to pull it off to check it all out. Therefore...while I'm in there... might as well change the gear and belt. We'll see what happens.

For no good reason, I don't like the sounds of using a belt that works on the Buell Blast- the Gates Poly PC-199-1 is $139.50 at Belt Drives.com

I,m don't know what the number of the belt is, my brother is going to try this on his ride. He has the pulley on order. The BDL Falcon #602-611 thru J&P Cycles.
When He does the change I'll put up a post.   Chilly

I put a gates poly on mine and got into lake placed two weeks ago when I picked up a rock.
3 days later I was back on the road again after finding a Falcon.
Thats the only downside with being on the road with a non stock belt.

I don't get it- do you have your belt guard on? Even if you did, a rock could make it's way in there and cause a problem regardless of what brand belt you have on.

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.

  Had the belt guard on, but the Harley belt guard is only half of what it was in 97. Not sure when they changed it.   If I can find the Buell number for a belt some shops could possibly have it in stock.
