I've recently bought a 2006 buell xb12x uly from a harley dealer. The mechanic there had laid it over in the parkinglot, so there is a few scratches. Not seeing any mechanical defects. The other day I was pulling out of a stop sign and accelerated through 1 to 2 to 3 then it would not let me shift to 4. I then drove it home in 3rd. We got it into neutral and took it to a shop. The shop doesn't see anything inside the primary but it shifts for him. He is weary that something is wrong inside the tranny but to get to it the whole engine and tranny have to be disassembled. So before we take it for a test drive or tear into all my money, I'd like any advice. Thank you | ||

The shifter shaft is mounted to a kind of bridge, and that moves a shift pawl assembly, that turns a shift drum. Most of that could be damaged in a low side, and you can get at most of it by pulling the primary cover and primary drive (clutch assembly, stator rotor, and primary chain) as a unit. I'd start there. | ||

We looked at that today. That all looks and functions good. This was of course with the bike stationary, could it act different while moving? The only thing I can think of is that the shift pawl didn't fully engage the shift drum when it locked up. My mechanic also found that 3 of the 6 clutch springs are loose but the pads look good. | ||

Check the lip on the inside of the primary cover that the clutch uses for pressure. It is known for breaking, which will keep your clutch from properly engaging. | ||

If that is the problem, here is a possible fix that may be less $$ than a new cover. http://www.badweatherbikers.com/buell/messages/384 2/282980.html | ||

I never heard of a primary cover popping other than a 2008 model. All of them do it? | ||
| Blakeaspencer |
I don't really see what that would do to cause the bike to stick in gear, then work fine later. | ||

Here's a thought: a drop could have resulted in a blow to the shifter shaft, which could shift the primary cover slightly, making the shaft bind inside the bushing in the primary cover. If you reinstall the primary cover and it works OK; problem solved. | ||

"mechanic also found that 3 of the 6 clutch springs are loose but the pads look good" Am I the only one confused by this? I have spent way too much time in my '06 XB12X primary in the early days. I can say that if you found more than 1 (diaphragm) spring in the clutch, something/someone is out of whack! that comment sounds like it was for a more conventional clutch design using multiple coil springs (typically 5 or 6). The "pads" comment I assume was meant to mean the friction plates? Neither the springs or plates are likely to cause the trouble you describe. they would more likely be the cause of slipping or some type of clutch engagement issue (or lack of engagement). If your mechanic really said that, you may want to question him some more. there must be some misunderstanding... | ||

I'm not exactly the best at being able to name things especially in the tranny. I'm trying my best to relay what my mechanic is telling me. We plan to fix those springs and then put it all back together. If it works then we either fixed the problem or covered it up. Either way I really appreciate the information and I will post what happens | ||
| Blakeaspencer |
We tore the clutch apart and found that the pads are 80% worn and the bearings are worn out and the spring plate needs to be replaced. Along with some other washers and things. All this comes to about $1000. Which is better than splitting the case and all that but seems a bit much for just a clutch assembly. | ||

Im sorry I still dont agree with that diagnosis. Im thinking that if it was laid over on the primary side, the shift shaft got bent and also gashed the shift shaft bushing. Mine did the exact same thing. replace shift shaft, hone the bushing a bit and itll shift nice. Itll shift just fine with a bent shift shaft if the primary cover is off. Not so much when its on. | ||
| Blakeaspencer |
If it is the shift shaft, wouldn't I have noticed it as soon as I drove it? I had it for a few months and it was just fine | ||

I'm also confused, is anyone "properly" trained (you've taken it apart & assembled without issue) local to this guy/gal who can help them out? This bike really isn't tough to figure out. If you're local to MD the bring it by Annapolis HD. I'll check out/ attempt to diagnose any XB. fo free I collect Ulysses mainly but have dealt with all XB models. | ||

However dumb it may sound, we put a new used clutch assembly in it and it works great. |
