I still like the idea of this:




Wonder how much overall weight you could save by converting from heavy chain to belt as well as removing the primary cover and fluid?


I also had a question. How are the transmission gears lubricated?

Primary fluid?

Oiling system?

IIRC open belt primary requires the trans fluid port b/t the primary and tranny to be welded shut.

But I cant remember how the oil gets in and out of the tranny.

When I put the 04 1203 motor in, I used the 03 984 primary gear AND chain. Didn't have an issue, I think the newer model your dealing with is the difference. If the sprocket and chain is purchased for same year model, shouldn't it fit fine. As stated earlier, all the clutch hub gears are the same.

Bringing this back from the dead, because I just did the swap last night. I know this has been discussed on here, but I was also concerned with the packaging of the new XB9 sprocket when I got it. P/N is 40241-02A ENGINE SPROCKET, 34T but packaging says 35T. Fortunately, it is the right sprocket with only 34T. Must be an incorrect label.

Has anyone else lightened up their rotor? I was amazed at how heavy this stuff is. Even more amazing was how much LIGHTER the new XB9 pulley is. The 40241-02A sprocket is exactly 900 g lighter than my stock 05 XB12 sprocket...so about 2 lbs! I'm pretty stoked to feel how this revs when it's back together. This might get me to lighten a rotor if it's as noticeable as I think it will be.

Thanks Froggy, I didn't realize you could do that. I think if more people realized this, we might have far fewer redundant posts...

Its an admin only feature, and its not a 1 click operation either. I read just about every post on here, so if I feel its worth reviving I will do it. : )

Well, I finished up this swap on Saturday AM and and had a chance to take her out for a good rip. I have to say, THIS is the way the bike was supposed to be. EVERYTHING is different about the bike now. It idles a little lumpier (less of a flywheel effect, as expected), and is MUCH more rev-able. Very nice, feels much closer to my XB9.

Road manners are similar to before, but all around better. Wheelies in first are now common (never was before with my riding style), and power wheelies in second are easily possible. All in all, it unsurprisingly reminds me of my 9 with a lower redline. Good recipe, IMO. I am no longer fumbling between first and second gear on really tight roads. Before, I was either lugging the hell out of second and/or modulating the clutch to get through the slow stuff. Not any more.

One thing that caught my eye during installation, though. I've seen some photos online where the rotor had some balancing done at the factory (three machined holes). Mine did not have any balancing that I could discern, and the manual made no reference of installation orientation. Did I miss something? Was orientation important on earlier models? Bike runs perfectly fine, but I'm just curious where the changes came in...

Lighten everything up even more by going to an aluminum clutch basket, front primary gear and transmission belt sprocket.

These components are very tough and strong, plus they cost the same as or less than the factory part!

I've been running these in my XB12R racebike for three seasons and they look like new and oh yeah, it cut 8lbs off the stock drivetrain!

Where does one get an aluminum drive pulley (belt)? I'd rather avoid aluminum sprockets, but maybe one day...

How much lighter was the aluminum drive pulley? That stock sucker is heavy. I'd venture to assume about half weight since it's aluminum, but...I'd like to know.

The guys to get these pieces from are not BadWeb sponsors so drop me a line and I can forward their website to you.

My Buell stats are out in my 10 degree (temperature) garage right now but if memory serves, the stock one was around 8lbs and the aluminum on was just over 1.5lbs.

Yep, it's a noticeable difference!

I need some help. I have a 2006 XB12X and I ordered the xb9 sprocket and chain from a sponsor dealer. I just went to put the sprocket on and the hole in the center for the shaft is about 1/4" too large. The part number I have is a 30018.08 apparently the wrong number. can someone tell me what the correct part number should be?

Sounds like you got the 2008+ sprocket for the bigger crankshaft. You want the following:

1 40005-57B CHAIN, PRIMARY, XL/BUELL
1 40241-02A ENGINE SPROCKET, 34T
8 4751 SCREW, HEX CAP
1 25378-02B GASKET, PRIMARY COVER
1 7839 NUT, FLANGED

You can get away w/o the hardware, but I bought it all just in case I damaged something during removal.
