Need some advice on the possibility of getting an XB back up and running.

I had two 2003 XB9S, one was my main rider, the other I bought but soon after the transmission locked up so I've been using as a parts bike (stuck in N). I recently wrecked my main rider. Because insurance is dumb, they want far too much to buy it back so I've decided to try and fix the other bike.

I don't know exactly whats wrong with the transmission besides it being stuck in N (between 4/5th gear if I remember) I had gotten as far as to disassemble the primary but no issues were found. It may be a bent fork or worse

Is it worth my time to tear it down and split the case? Is it even possible to still get the forks/gears should I need them? Or should I just try to sell the bike and combine it with my insurance refund?

How good a wrench are you? Need to pull the engine which leaves a one wheeled bike, then tear it down nearly completely to get to trans,most likely bent shift fork. And then basically rebuild the engine on your way back together. It is only time and money----

I've already done top end work to this bike and the one I wrecked (replacing cylinder heads/gaskets/etc) I've never split the case or done any lower engine work but I have the shop manual and the internet.

I'm not TOO terribly worried about the actual work involved but I am worried about the parts availability, which is why I'm asking this now before I tear into it. I don't want to get the bike completely apart and find out my only option is buying a donor engine.

Can I still get just the forks/whatever individual transmission parts?

Pick up the phone and call Lance (or e-mail. AKA Lance651 here on the board) in the parts dept at St Paul H-D in St. Paul Minn. He'll know.

Most if not all internal transmission parts are the same as from a Sportster. So Your chances are good to get parts from HD.

At one point they switched from straight gears to helical gears, not sure what year. Transmission for tubers is different than for XBs. Some parts are shared but others are not.

Get the parts book for your model and make a list of everything you need with part numbers. If you buy any part off other models you can use the list to cross check against parts manual of other model.

06 is when Buells switched to helicut gears. The XB transmissions are quite different from Sportsters. Individual pieces may be similar and share some p/ns, but the XB uses dual shifter rails whereas a Sportster still uses a single shift rail.

Appreciate all the responses. I think I've decided to just throw a different engine in it and either sell the miffed one (to recoup cost) or work on it to figure out what went wrong

I can only think of two reason that you would be stuck in neutral.

1) The detent plate has fallen off/disengaged from the shift drum.

2) The shift forks aren't moving when the drum is turned. This can happen if the shift fork pins are not engaged in the groove in the shift drum. This is the track and pins that translate drum rotation into left or right fork movement.

Each shift fork has a pin that rides in the grooves of the shift drum. Each pin is held in place by a cotter pin. I've heard of the cotter pins breaking and allowing the shift fork/drum pin to fall out. If that were to happen the fork would not move when the drum in turned.

To test the shift fork idea I might use gravity to try to drop a gear into place. Lay the bike all the way on its side and turn the wheel to see if it engages or tries to engage the gears.

Right now the primary is taken apart so I wouldn't be able to tell if the shifting works. I may diagnosis it once I get the "new" engine in.

That's a clever idea!
