RC390 Cup Bike want start unless its a neutral

[Bikingbagga]

Found out at the track that my CUP bike will not start unless it is in nuetral. Most bikes if you pull in the clutch when its is in gear the bike will start. Mine will not
What is the fix?

the behavior you describe would occur if the clutch sensor were broken. If you've changed levers recently and weren't careful this might have happened.

I have not changed anything. I got the bike as did not realise I had the issue until I stalled the bike on the line at the start of race and could not restart when I pulled in the clutch.
Exactly what is the location of the clutch sensor?

 

[pineappleguru]

it's a small switch that connects to the clutch lever on the bottom side

My clutch perch has no electrical connections

seems like you found your problem then

 

[Bikingbagga]

I have not found the problem

if your clutch perch has no electrical connections your clutch sensor is missing. if your clutch sensor is missing the bike has no way to know whether the clutch is pulled in or not. if the bike doesn't know the clutch is pulled in it will not start when its in gear. simply install a clutch sensor, and the problem would probably be fixed.

Why can you not elimnate trhe sensor completly

 

[pineappleguru]

if you eliminate the sensor completely you'll probably need to short circuit the ecu somewhere, if you want to know why you can't unplug it and have the bike work read through the logic of my last comment
