Differences between 2003 & 2005 XB9

[DSophia]

Hello all! I’m the proud new owner of a 2005 XB9SX. I fell in love with it immediately. Unfortunately it came with an issue. When accelerating the revs stop at 3000-3500rpm. I’ve reset TPS, static timing, checked for intake leaks, and replaced ignition coil that was reading just under spec. Still an issue. I recently found a 2003 XB9S parts bike a few hours away. Are there enough interchangeable parts on the 2003 to make it worth buying? Thanks for any help, excited to be a part of the forum.

You probably should buy a Buelltooth module and get a copy of ECMDroid so you can do some data logging on the bike to see what is going on at that point. It could be fuel pump volume, or something like someone changed the tuning to have the rev limiter cut out at 3500. Without more detail its difficult to tell what is going on.

Before you ask "who would do that to a Buell?"

Most 2003 parts should cross over, but not all. If you buy that parts bike, the only parts you will need are the ones that will be different. But, I am looking for the headlight castings for a Lightning, which may help make the decision to purchase it easier.

Thanks for the quick reply. I have new info to help diagnose. I just drove it a few miles to make sure it was getting clean fuel and realized it would rev well above 3500 as long as the throttle wasn’t pulled back to that sweet spot. Does this mean it’s the TPS since it’s directly linked to the position of the throttle?

The parts I’m most interested in at the moment are a seat, tank/intake cover, windshield, gas cap, tires, and maybe the transmission. Should all of that fit?

Yes, those should all fit.

Seats are still available new. Some of the tank/intake covers are as well. Windshields are hard to find, gas cap is still available new. The transmission should fit, but realize you need to take the bike completely apart (literally) to get at the transmission. So, unless you're willing to jump through those hoops, you may want to reconsider. This motor is not a Sportster motor with a trapdoor.

I’m not excited to break it apart to do any work, but would be nice to have an extra set of parts for $500. I’d just like to know it’s worth the investment. I’ve owned very efficient and powerful bikes but this one is by far my favorite. They really do have soul, I’d like to keep it for a very long time.

I’m having trouble finding a BuellTooth module, the site that carries them is sold out. Any leads on where to get one?

I see there is a version 2 module that is in stock. Can anyone tell me if this is worth the money if I’ve already got the ECM cable and ecmspy set up? I am unfamiliar. Thanks

Do you want a wireless set up or a cabled setup? If you are comfortable carrying around a laptop cabled into your bike while riding around datalogging... go for it. If you'd rather have a wireless setup that will interface with an android tablet or phone via Bluetooth, the Buelltooth module is the way to go.

If you are unfamiliar with these basics, you probably shouldnt be playing around with ECMSpy.

Being that you are having these difficulties, I recommend taking a course at the your local community college about the internet and google (or other search engines). Once you master that, you should be able find several sites that will provide instructions on how to use ECMSpy.

You are by far the funniest guy I’ve met on here so far. I can tell which college you decided to attend. Thanks for all the info.

I’m having trouble finding a BuellTooth module,

Give up now. A google search of "BuellTooth" has the first listing of where to get one.

the site that carries them is sold out.

Funny, it says "add to cart" and not "sold out"

or you can buy an Arduino or other brand of Bluetooth project board, wire in a 5v power regulator and source the correct molex and pins and build one yourself and save big $$$$$.
