Changed the rear isolators on my S3 and decided to "upgrade" the belt to the newer style xb belt that should have a longer life. Length is fine, pulley grooves all seem to align but I can not run the belt anywhere near as loose as the old one without it spinning on the counter shaft pulley. The old belt could flop around and I could still lift the wheel with a crack of the throttle. The new belt is tighter than the manual spec and it will still slip when under load. Anyone else have this issue or find a belt tension that worked without being over tight? I always preferred running my belts loose, but does not seem feasible with the XB style belt.

I've been running one on my S3 for years and have the same problem.

Support the bike, disconnect the shock and align the axle with the swing arm pivot and pulley.

this would be the tightest spot in the swingarm arc.

Tighten the belt as tight on this spot as seems reasonable.

You should not be able to push it very far at all.

Attach the shock and adjust the sag if needed.

If it still slips tighten it just enough to stop it or adjust the sag so that you lower the back of the bike enough to stop it (the belt will get tighter as you lower the bike).

I can still get mine to touch the swingarm, but just barely.

They do break in over time a bit.

FYI I wouldn't go this route again if I were buying a new belt.

The problem is that the XB belts were designed with more rubber, to be back bend-able for use with a tensioner. Without a tensioner, they don't have as much grip as the Sportster-based high Kevlar content Gates belts. You can't use a tensioner with a Gates belt, but a Goodyear belt is not ideal without one.

Thanks all, some good advice and at least I know the problem is not unique to me. As Scott indicates, I don't think I would go this route again, but hate to remove isolators to replace, especially since I went to the longer lasting belt specifically to avoid the isolator process for as long as possible. Does anyone know of a tensioner adapted to the tube frames?

Free Spirits makes or made one. I think Marc (Purpony) just built one for Ken; you might hit him up and see if he'll build another, as that would likely be faster than ordering one for Free Spirits across the pond.

I've been running an XB ('04 or newer) belt on my X1 for the last 8000 miles, set scary loose, and have had no slipping issues. Still looks like brand new.

Sounds like an opportunity to utilize 3d printing to generate a prototype.

We would be interested in exploring that option

Ofcourse you would need to do your own design work as this is for a tuber with an XB swing arm so no adjustable axles.
You can order a free spirit they do still have them

Can you share a PN with us?
I could be wrong, but I think a stiffer one was developed for the Ulysses or at least believe their is more than one XB belt.

I have about 10,000 miles on mine and adjusting it so that it is tight, but not overly tight when all three shafts are aligned has not caused any problems.

That said, I'd rather be able to have it loose...

The Uly belt is 135 teeth instead of 128 teeth, so it won't fit unless you're running XB wheels and pulley on a tuber.}

118 teeth

Must've gotten into a bar fight over the weekend and lost some teeth...

Sportster and standard Buell belts are 128 teeth, AFAIR...

Ok, I still think that either a new stiffer XB belt replaced the original XB belt or there are two PN's.

It was probably 8-10 years ago, so I don't recall the specifics.

I can guarantee you that the XB belt on my S3 will skip on any stock tuber if left as loose as the stocker!

The lightning long also has 135 teeth, as it uses the longer Uly swingarm. Make sure you didn't get a lightning long belt

Scott are you using a 27 tooth counter shaft pulley? My S3 came with a 29 originally (that may have only been true for 97). I wanted the lower gearing and installed a 27. I am wondering if two teeth are enough to make a difference and might try the larger pulley, or it could be a NH effect since that is also where my S3 lives, but there is no way this belt won't slip at the stock tension setting on a 27 tooth pulley.

My pulley is stock, not sure what they came with in 99
EDIT: the service manual says 27 tooth

The XB belts went through constant revisions for strength. The higher the letter at the end of the part number, the later the revision.

That said, I'm getting ready to ride my S2 to work. 35k miles, still wears the OEM belt that says "Sportster" on it : )

I was about to say something similar.
The sportster belts are technically not as good but they are easier to get from dealers and my first one lasted over 40,000 miles.

If the DRIVE BELT is properly adjusted weather or not it has a IDLER or not will stand the test and out last the rest ...

DRIVE BELT ADJUSTMENT Class 101, PM me if you want a copy ...

In my 1997 S3 Parts Books the BELT, drive is PN 40014-94Y(128T) in the BUELL Harley-Davidson part numbering system ...

The "SPORTSTER" DRIVE, belt is PN 40022-91(128T)...

The -94Y and -91 is the first year this Part Number was used and the HIGH CASE LETTER means the part was UP-DATED ...

In the Harley-Davidson Part Number System the letter A would mean the first up-date and a B the second ...

The BUELL "BUELLschitte" part numbering numbering system as in G0500.T, just who in the hell knows ???

LaFayette, your info is much appreciated, and applicable with the stock belt. We are talking, however, about when using an XB Goodyear belt, which is of very different construction and material. The Sportster/tuber belts (high Kevlar content by Gates) are not supposed to be back bent, so a tensioner will cause them to prematurely fail. The Goodyear XB belts are made for a tensioner, however, and are meant to withstand much more stretching and movement than the Gates belts, hence why we believe this is causing the problem.

BUELLschitte

Almost synonymous with Buellistic, is it not?

The -94Y and -91 is the first year this Part Number was used and the HIGH CASE LETTER means the part was UP-DATED ...

This is generally true, however the Y identifier after the 2 digit numerical designation was chosen - probably by some all-knowing person at H-D - to reflect a Buell part. For instance -94Y parts started on the S2.

G0500.T, just who in the hell knows ???

Well, that is VERY simple. My answer is 'I know!' That's a Blast drive belt. The ".T" identifier was for the Thor project - a.k.a. the Blast! G0500 has always been the main part number for a Buell drive belt - when following the Buell part number convention.

As Ross pointed out this discussion is about using an XB belt on a tuber, so let's please keep on topic!

mine is a G0500.1AAE

I just got back from a 700 mile ride up to and around Acadia National Park, Cadillac Mountain and Bar Harbor area

This was my first ride after fixing the damage caused by the broken anti-rotation pin

Because I just got it back together, I haven't run it to redlline through the gears, but I have don't quick rolls on in each gear.

The one time I did it in 1st it did jump a few teeth

Checking the belt now it can fully contact a large portion of the top of the swingarm

I need to use Lafayette's method because that is the only one that insures it isn't getting overly tight during suspension travel

With this belt, you need to be as tight as you think it can go without overstressing any bearing

If I can't get an adjustment I like, what is the strongest belt meant for a tuber/sportster?

The XB belts get noticeably more limber with use; I'd guess you'd need to re-adjust it a few times as it breaks in. Maybe after it's got a few hundred miles on it and the tension is properly adjusted (scary loose) it won't slip?

After seeing this to be a recurring issue, I think the best solution is either a tensioner or going back to the Sportster-derived belt.

Looked on the Free Spirit site but they do not seem to ship to the US, and based on the conversion to pounds, the tensioner is quite pricey. I do have a 28 tooth Baker pulley I may try (I doubt one more tooth will make a difference, but perhaps combined with Lafayette's approach it will solve this problem). In the mean time, I will ride the Dyna.

5-dro a site sponsor can get the free spirit part but from what I remember to my door was like 350.
There is a simpler way to put a tensioner on
Foximus had one on his S1

Hey guys,

I'd like to revisit this subject because I either need to change back to a Gates belt or add a tensioner.

I don't want to buy a new belt or go through the hassle of changing it and I don't want to spend $3 bills on the Free Spirits solution so...

S1owner would you make another? I'll source my own XB roller, or would you be willing to share the dimensions and I'll cut my own from some 1/2" aluminum.

Thanks,

Scott

Couple things to note
Mine will not work with the Standard swing arm. I have a xb swingarm and it requires a longer belt.

You would need to mock up the piece so it had the correct tension on your set up.

I did not make it just designed it.
