| | Re: Clutch Stuck in engaged position Thanks motor head. I rechecked the cable and it is fine. There is a pin that seems like it should move in and out to engage and disengage the clutch. The pin is in the shaft that the small sprocket is on, that comes out of the motor itself. It seems like the pin should get pushed in when you pull the clutch lever, but it is stuck in the out position. |

| | Re: Clutch Stuck in engaged position How are you trying to push that pin in? You won't be able to do it with your hand or fingers. The clutch actuator is supposed to do that. The actuator is the cam inside the clutch actuator cover, left side. Are you sure you have the clutch cable adjusted correctly? It should have little to no slack where it is attached to the clutch actuator arm on the engine. If this is a new engine then the clutch might be stuck from the factory. Try striking that pin with a good blow from a plastic headed hammer. Don't beat it to death just give it a good solid hit and see if it frees up the stuck clutch friction pads. Get back to us if these things don't help.

| | Re: Clutch Stuck in engaged position If you are the same "wishesdontdodishes" from that other bike forum, i'd be curious to see how you attached the motor to your unicycle. Please post a video... it sounds pretty dangerous, so be careful! |

| | Re: Clutch Stuck in engaged position There's a topic for another forum, but to answer your question I never got it to work predictably. It's a shame too. Several NBA teams and a Vegas casino were offering appearance money. I say good luck to anyone getting a gas powered unicycle to work before the old lady throws you out. My advice...feather that throttle.  |

| | Re: Clutch Stuck in engaged position Sorry, I have the same problem. Did you tap the pin or the flower nut? Where is the flower nut? |

The pin is in the center of the engine drive sprocket, left side of engine behind the clutch actuator cover. The flower nut is behind the right side engine cover, rear, center of clutch pressure plate. Tapping either will usually release a stuck clutch. Make sure that your clutch cable is adjusted correctly also. It should have little to no slack in it where it attaches to the clutch actuator arm with the clutch lever (on the handlebar) is released.
