no start with clutch held in

Weird situation. Bike will not crank unless the clutch is released. It has to be about halfway released before the bike will crank. In neutral of course.

Didn't use to do this, just started. So its a PITA to have to find neutral in order to start the bike. What would cause this? Clutch lever sensor? I have no clue really, its odd. Seems like it is working backwards... wouldn't you normally have to hold a clutch in before it lets you start? like on a car?

I am not sure if you solved your problem .
The bike should start in neutral and/or in any transmission position with clutch in.
The clutch switch went bad on mine and I thought it was normal until I met someone with a zx12r and noticed his started with clutch in....needless to say it was under warranty at the time and I had the switch replaced.....which went bad again in less then a year. So I removed the switch and found that it can easily be taken apart. I cleaned the contacts inside and then packed the switch with grease to keep the water out its been atleast 5 years no problems......

The clutch safety switch is one of those parts that wears out prematurely since it is actually tripped every time you use the clutch to shift.

So your saying that I should be able to start the bike if the clutch is pulled in? As well as in neutral with the clutch released?

My bike started doing the same thing. Then the resovoir started boiling over now. I dont think its the head gasket cause the oil is not milky. May the clutch switch be causing this?

Assuming you mean the coolant reservoir by your left knee then the clutch switch is really unlikely to be causing that.

You only get mayo when oil and water mix - you could have a blown head gasket pressurizing the water system without any mayo showing.

When the coolant "boils" is the engine temp showing really hot on the dash and is the rad fan running?

It only took me a month but finally got around to dismantling my clutch switch to have a look...

Only took a couple of mins - it's a piece of piss to do - contacts inside were covered in oily crap, quick spray of degreaser and a wipe out with clean cloth and the job was done!

Bike now starts in gear with the clutch pulled in for the first time since i owned it!
