Hello all-

I have a 2005 150PX that was running great and then I could no get it to shift out of 3rd. When I stopped I was able to move the Gear Selector "left handle" with out pressing the clutch. When I checked the Gear Selector "Batwing" the cables are still attached and moves freely when moving the left handle. The clutch arm still has the cable attached and there is tension and moves when you press the clutch handle. Anything else I should check before opening things up more? She starts just fine, just can't get it to move....seems like the clutch is still activated somehow.

Thanks in advance.

Wild ass guess: cruciform came loose. Undo two bolts that hold shift selector on, then shift the handlebar past fourth and it pops right off, cables attached. Reverse the process to pull it back on the studs after. The cruciform goes on counter clockwise and needs a nice torquing down once threaded nicely.

Can be done without splitting cases.

Maybe the pin came out of the selector/batwing shaft and arm inside the selector box.

OP, post up some pictures. Those help tremendously with diagnosis. Videos are even better.

I agree that your cruciform probably came unthreaded somehow, especially if the cables are fine.

Have you pulled the cover off and observed the batwing? Can you confirm the whole unit is turning like it "should" (other than the whole "not shifting" part)?

If so, then your next step, as others said, is to remove the selector box. If it *is* the cruciform, then the whole unit will just pull off, including the selector shaft. If it requires any sort of effort to work the selector box off the shaft, the cruciform is still connected, which isn't necessarily bad, it just sends us in some other diagnostic direction.

If it is the cruciform, use (edited) a wrench to grab the flat part of the shifting shaft (after getting it started on the threads of the cruciform) and remember it is reverse threaded, which means rotate the opposite of how you think it should thread. Get it nice and super snug.

When putting shifter box back on, get the swivel-bit nicely mated with the flat part of the shifter-shaft-thing (you shifted past fourth gear earlier so it's easy), and use your toe to push the box while shifting back up to first with your left hand on handlebar. You want to 'pull' the selector box back on.

It should be easy. If it's a nightmare, you are doing it wrong ;D

DON'T USE PLIERS!!!

Use a 13 or 14mm wrench (I forget which). It'll fit and won't scrape up the surface. Plus, it'll be easier to manage since you won't be trying to manage your grip on the pliers at the same time. In this case, it might not cause issues, but it will be easier to just do it right.
