Like Nickj says , the oil light wont go out till the engine starts.

1. Check its definately not in gear (go through the whole gearbox if necessary)
This sounds most likely the prob, as has been said above.
2. Check all block connectors to ensure they are dry & have no corrosion.
3. Have you tried bump starting it?
4. Have you tried putting a power straight to the starter motor?
To do this: Pull the boot off the wire that goes to the starter motor & with a set of jump leads or a jump pack clip the earth lead anywhere onto the engine & flash the positive lead to the starter motor to see if it fires (tho you MUST check its in neutral first & that the ignition is on) If this works, then there isnt a problem in the ignition circuit - you'll have to look elsewhere.
To be safe, get someone to hold the clutch in while you flash the starter

Let us know what you find

I used to have a similar problem with my old 916, the neutral light was never especially accurate and sometimes would be on when it was in gear and other times it would be unlit even when the I could freely wheel it about. If the ignition on your bike is similar to this it may just be a case of lightly snicking the gear lever around neutral until the light comes on, its infuriating sometimes but I got used to it.
Does your clutch drag perchance?

Round the back of the engine, behind the clutch side you'll see a single wire going into the back of the cases.

Wiggle it and see if the neutral light comes on.

If it does, pull the wire gently out and give the connector a squirt wth WD40 and a LITTLE squeeze with some pliers, then plug it back in

By George you were right! what is it? Knew it was something stupid

When you say pull the wire out, do you mean with the white plastic bit as well?

Anyway, thanks all

Thats the neutral light wire, the bit it plugs into behind the engine is the neutral light switch.

The white plastic bit is the plug on the end of the wire, it should come out with the wire.

Unplug it if possible.

Had this happen a couple of times on mine over the past month. Done as crust suggested (great post!), the switch was a little loose so got cleaned and tightened. Hopefully that will be the last of it

Hi, the bike won't start if the sidestand down and in gear. There is a small switch under the clutch lever, if the bike is in gear, you need to pull in the clutch lever in order to start the bike.
