I'm experiencing a weird glitch with my Fazer. If I ride it half a mile to the fuel station (or similar), leave it a few minutes, when I come back to it, the bike refuses to start in neutral - the engine turns over, but doesn't fire. When I kick it into first, however, it often starts straight away. Why!? Any ideas?
-
I was about to ask if the side stand was down but that would have the opposite effect. Could it be something wrong with the side stand up-down sensor?

I thought that - but why would it only refuse to start in neutral when the engine is warm? Starting cold isn't a problem at all.
Am well confused!! :\

Starting in first gear means you have the clutch pulled in. Does it start in neutral with the clutch in?
In a car, that could be the sign of a flooded engine. Don't know if that applies to a bike.

No - if the neutral light is on, the bike doesn't like to start. Sometimes, it needs the clutch barely disengaged to kick in to life - it's very strange! It's always after a short spin (under 10mins) when the bike's been off for a few minutes. Cold, or just switched off is fine. It's a mystery!!
-
I don't know if this makes a difference, but my usual shut down procedure is kill switch, ignition off. Starting, it's kill switch, ignition on, starter. And never more than 10 second bursts at a time (normally starts under a second) - 5s bursts usually.
-
Are you saying that you are killing the engine with the kill switch every time you stop?
As far as I'm aware that's a big no no. You should turn the ignition off first, then if you must, hit the killswitch and then deploy the side stand or get off and put on to the side stand / centre stand

Mostly. But I can't see why it's a no-no (apart from wearing out the switch), as it does the same as the ignition. I can't see how that would be linked to the neutral problem though? Surely then it would affect the bike in all gears?

I have never used the killswitch on my bike. Come to think of it, I don't even know if it works. :S

I have no idea, it's just something that I have picked up from somewhere but I have no idea as to whether its accurate
There are several other threads where people have had intermittent starting issues and the have described your problem exactly

:hijack
I stop with front brake, clutch in, right foot down.
I then select neutral, put down the side stand, rest on stand and turn off ignition.
Right or wrong ?
-
Almost right until the last bit. Should switch off the engine before putting the side stand down :) This is what I was taught by the riding school, not just some random figment of my imagination as above :P

Because its very easy to accidentally knock into first gear whilst attempting to put side stand down, hence switch off engine first otherwise she pops forward!

Precisely the reason the instructors gave :D

Thanks for the explanation :-)

I'm no mechanic, but I wonder if this is a clutch switch problem?
-
I'd have to check but I fairly sure side stand clutch switch etc stop the starter motor but I think the kill switch just stops it running. I'll try it later.
-
How could the clutch switch cause this? I had an issue with mine whereby pulling in the clutch still wouldn't let me start in gear. Ended up taking a stanley blade to it and cut a bit off the end of the plastic nubbin bit and now it works perfectly :D With the clutch out and in gear, it won't start but pull in the clutch and away it goes - I was expecting the first part to fail and for it to just permanently think that the clutch was pulled in - something I could live with if I had to, so this was a good result for an extreme measure

Mine won't start unless it's in neutral which is an arse if you stall it in first. I suppose the solution is not to stall :think
-
In that case, do what I did! I had the same fault
Use a stanley knife or some side cutters and just snip off a bit of the end of the black plastic lug on the switch :) Mine now works perfectly

Fault or feature ? ;)
-
It's a fault... you should be able to start the bike in any gear as long as the clutch is pulled in
-
Christo
have you checked the valve clearances?
Charlie :smokin

Which switch pls ?

No. But, the bike is only on 28,000 miles, and I have no problems starting cold, or any other problem that would suggest valves.
I also fail to understand how the gearbox would affect the valves? The only thing I can think of is that it puts a slight load on the engine. But why would it want a load? I'm thorougly baffled...
-
If the engine is turning over doesn't that rule out all of the cut out switches? Can't see any problems from stopping with the kill switch. Its a switch the same as any other.

Don't look at me, that's why I'm asking!! :'(
-
When you're having the problem does the engine still always turn over?
-

Yep, but it only grinds away. It only fires (sparks) when in 1st. But it's been doing it less recently.
I am very confused.

Sounds like sticking clutch switch. Spray WD40 all around and into the clutch switch and see it it sorts it out.
The kill switch debate is from olden days when bikes turned over, but would not start with he kill switch off and was the reason for many mechanic call outs. Newbies were told not to use the kill switches.
It is probably the safest and quickest way to stop any bike. It prevents (as already stated) the problem of kicking it into gear when kicking the sidestand down.

I could understand a sticking clutch switch - but it's doing the reverse of what I'd expect? It's an odd 'un.

Mines having a bit of trouble starting in the hot weather...

There is a switch on the handlebars mounted underneath the clutch lever. When the lever is pulled in, it pushes a black plastic plunger in to the housing to activate the switch - I cut down the size of this plastic bit
I'll try and get a photo for you :) If you don't get around to it, come to a LoFo rideout and I'll bring along some side-cutters and do it for you :P

Just to get this straight, which is it?
When you press the starter button with the bike in neutral the engine turns over, but will not start and if you pull in the clutch and put it into first gear and press the starter button it will start?
OR
When you press the starter button with the bike in neutral a relay chatters, but will not start and if you pull in the clutch and put it into first gear and press the starter button it will start?

First one. And it hasn't done it in a while now either, I'm properly baffled. Why was it doing it, why did it stop, and will it do it again?
-
That rules out many of the starting circuit switches as the engine would not turn over if they were faulty. Might be worth while taking the connectors apart and spraying with WD40 as you might have a corrosion problem. Lift the tank and do all in the box under the tank and the coil and pump connectors as you have the tank, remove the left infill panel and do the ones to the clocks, the starter cut out realy connectors under the left hand side cover and finally the alarm bypass connectors under the seat .
-
Christo, got an alarm fitted?
-
No, as far as I know, the only mod to the loom is where I bypassed the ignition barrel to get my rear & side lights working again (shorn wire at the barrel). And the 12v is a) connected to the battery, and b) has blown up.
