Bike stalls when clutch is disengaged

Mechanical issue: clutch not disengaging completely...
engine off - put in gear and roll back and forth with clutch released does engine stop the bike from rolling? Now pull clutch lever in and try rolling again is clutch cable adjusted properly?
Electrical issue: bike thinks clutch is still engaged and kills motor when not in neutral
Is the clutch switch properly connected and working? Is it adjusted properly? Use a multimeter to read resistance across switch contacts does it change state when clutch is pulled in?

You can kill the engine with the PTO clutch on and then turn the PTO off before trying to restart because the PTO will auto disengage when the engine switch is turned off. The engine should not start if the PTO switch is on.

Usually when that happens that leads me to believe that there is a clutch switch. It should have restarted if the clutch lever was being held in while trying to start it in gear then either the clutch switch is bad or the kick stand switch. Test each one to find out which one is the culprit.

If you are at idle, in neutral, with the clutch lever pulled all the way in, and you shift into gear and the engine dies, it is likely the switch at the clutch lever. When they fail the bike does not get the signal that the clutch is disengaged and it is safe to shift into gear. Have that switch checked. Some bikes also have a side stand switch, make sure your side stand is always up before putting you bike into gear.

Check to ensure the hydraulic mechanism is working properly and hasn't leaked. If it has leaked or there is air in the system, it wont allow the clutch to disengage properly and would be akin to a clutch cable being out of adjustment or broken. If the yydraulic release is working as it should be, you may have oil fouled clutch plates. Oil fouled plates would cause the bike to jump/lurch from a stop and could also stick together.

from memory it serves me right but it is something to do with the sensor on your side stand as this is one of the only ways they can stop you riding off with it down. if this is not the problem the idle signs lead me to believe it is a kill switch or imobiliser.

hope this helps?

It will have a side stand switch, which will kill the engine if the stand is left down, it opperates in conjunction with the switch under the clutch lever, and the neutral light
These side stand switches are small micro switches and often fail , wear out, or just come loose
The switch under the clutch seems to be ok , as it is doing what it is supposed to do, when it thinks the side stand is down

What kind of oil is in the crankcase? Wet clutches take a sprcial oil, noy motor oil. If oil is correct, Is the cable and release levers fully disengaging the clutch? There is an adjustment for the rod inside the clutcjh hub . That could be short stroking.

Have you tried adjusting your clutch cable? If the clutch was bad you would rev the engine in gear but the bike would not speed up as it should because the clutch was slipping. But if your cable is out of adjustment pulling the lever may not be disengaging the clutch. You should find the adjustment at the clutch lever, should be a larger locknut and a smaller adjusting screw. You want about 1/2" of freeplay in the lever before it starts disengaging the clutch.

Did it stall with a big **** like you didn't pull in the lever or did it just die? If it died, maybe the sidestand switch is faulting, killing the engine because it thinks your kickstand is still down.

Hi and welcome to FixYa,

Initially, if the bike will be run without its own battery, the engine will really stall. This is because there will be no consumer for the voltage output other than the ignition system which will clamp down when the engine is revved and the voltage tends to go higher still.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
