While not proof of anything, just the fact that so many folks have reported very short life with the Falcon belts would lead me to suspect there is a manufacturing or design problem.  And there is another possible reason, other than back bending or running a belt too tight, for a straight across clean break with no obvious physical damage.  It's called a butt joint failure.

Well I highly doubt it is a puley issue if they are that new. I never heard of a belt breaking due to being too loose? That's what is great about the net. The other here have seen it. Let me just throw a few belt facts out I learned from a Gates Factory rep:

Never twist a poly-chain belt ( to store like done with fan belts)
Never hang a belt on a nail or screw.
Never bend a belt less than a 6" radius ( this can cause cords to break)
They should be store flat!

So if pullies are good condition and belt was stored properly then unless you are seriously beating it like holeshoots and wheelies it sounds like a bad belt. The fact others had issues with this belt also makes me think they might not be a great product. Makes you ponder the question did you really save any money over a Harley Gates belt? Labor to change again, Aggravation, Time you can't ride your bike. Food for thought not trying to pick an open sore!......FACE

I don't think it was a question of price faceracer, but more a question of availability.  Certain sizes are not available from H-D, so when changing belt size when doing a sprocket size change, people often have to look at other sources.  The one that seems to be most common in the Harley aftermarket is Falcon.  From all the bad press here and elsewhere, I'm guessing Falcon isn't the best choice for a late model Harley. 

Steve at Fullsac has another thread running where he showed how to modify the swingarm to allow folks to run the stock Harley belt when changing trans sprockets.  Maybe that's the way to approach the gearing change rather than depend on iffy quality belts.

makes me wonder if you could not order it direct from gates? I used to work on High speed packaging machinery and we used a dozen different sizes lengths and widths. I bet its a matter of contacting gates. I had a new gates belt take a black top rock and made a hole right thru the middle. It was a nearly new belt. I bought a hd emergency spare and put it in the saddlebag. That was in the mid 90's and I sold the bike in 07 with the same belt and around 40K miles on it. That was on my FXR which did get run hard!!!! Point being I think gates makes a Superior product? At least that's my experience! FACE

I just attended some belt training at work furnished by Gates. They told me if your belt breaks and it's straight across the width more than likely the belt was not tight enough. I believe he called that condition cupping.  HD also owns the rights for the belts they have Gates provide. hey would not provide any detail other than that.

I'm not an expert by any means just pasing on some info I learned.

Hi,
My belt is 12 years old. 2000 FXR4 CVO (1.5" wide belt). I now have a S&S V111 with 116 HP/122 TQ and I run it pretty good at times but
no wheelies or burnouts yet. My belt used to squeek when decelerating. Belt was a little loose, tightened and all good now. S&S Has a belt made by gates that has X3N carbon cord technology that is suppossed to be alot sstronger than the Aramid used by many manufactures. made in 1 1/2" and 1 1/8" wide in assorted tooth counts.

The belt is junk regardless how you ride. on my 2nd and a spare in the bag. I guess I'll get around to a fix soon.

I have the same situation and a Gates belt is not available for my bike. It seems that Falcon is the only manufacturer which makes a 1 inch 135 tooth for the 2007 CVO. I am not concerned about the money to change the belt as much as I am about being stranded in the middle of no where with a broken part. I any one knows the part number for a belt in the correct size  manufactured by Gates i would be thankful and inclined to change mine at the next service.  I have also considered going to a larger 1 1/8 inch wide rear pulley and buying a S&S belt but I am not sure if it would fit or work..Any input from the experts here is appreciated, I do not want to modify my swing arm to make the stock belt work if there is a solution out there and I do not know what it is.....

Dont you already have the larger belt on the 07

Not according to my service manager who is convinced it is a 1 inch belt. If it were an 1 1/8 inch I would have a couple of options.  If he is wrong I would like to know. I have installed the Tri-glide pulley on the front so there is absolutely room for the belt to grow in width. The  issue seems to be the rear pulley width. So to the experts out there, is the rear pully on a 2007 CVO Ultra capable of using a wider belt or am I married to the 1 inch belt as my dealership states. Any additional input in this area is valuable for future decisions..thanks

[grc]

You don't need a service manager to tell you how wide your belt is, get a tape measure or other scale and measure it.  A one inch belt will measure one inch across.  It really is that simple.

btw, all belts were changed to the current one inch wide version for the 2007 model year.

The belt number I used is 40056-07 that i used on my 07 CVO Ultra
I have the belt it is used in good condition was on the old bike for 10 thousand miles
Belt Number shows that it is a good part #
136T belt
Why are you looking for a belt that is 2 teeth shorter you should only need 1 shorter

[RayG]

Why are you replacing a 137 T for the 2007/2008 for a Falcon 135 T?  You can get an 136T OEM belt which will fine for the 30t conversion.  I had the 135T Falcon for a very short time, wouldn't put another on if it was free.   

[sleepybare]

this is great information, I can get a 1 inch 136  tooth gates belt through HD. Maybe its my ignorance but I thought a 136 tooth belt would be to long for the 30 tooth gear change but if it works I will be very happy. Thats why I belong to this site, lots of good information for the person who does not know....your input is greatly appreciated

This is the MOCO OEM 136 tooth belt that works fine on an 07 with the 30 tooth gear change.  Surdyke offers a great price...
