Title: some advise please
Post by: dlighthill on September 08, 2008, 06:56:30 AM
i was changing my chain and sprockets, both front and rear, yesterday and now my bike won't start. it doesn't even click like it's trying. the lights work and i had it on the charger to make sure it wasn't the battery. i'm wondering if something came loose? when i removed the front cover to do the front sprocket it was filled with grease and o-rings, so i made sure to clean it out very well (i've never seen a chain throw all it's o-rings before).
suggestions would be helpful.....thanks

Check that it's not in gear,side stand up and the 10A starter relay fuse is good....

didn't seem like it was in gear - green neutral light was on
i tried to start it with the side stand both up and down
where would i find the starter relay fuse?

Starter relay is behind right side frame cover,you can trace it from the (+) battery terminal

the fuse is inside and it's 20 A not 10A

Sidestand interlock switch is in the area of the sprocket cover, you might have disturbed it.

Might be a kickstand problem, a friends bike wouldn't start, after all the troubleshooting, i bent down and cleaned the inch of grease on his kickstand and it started right up, guess it was stuck down.  Also check your fuses. Chef

would all the crap (grease and o-rings) have caused it to start with the side stand down? it used to do that.

Yes............If the switch had stuck in the closed position.

^^^^OK
BUT you can start the bike with side stand down, if the bike is in neutral.
Make sure the clutch is working properly, you have to disengage it (pull a handle) to start the engine.

Yes and no.............depends on the bike and where you are. UK and some other Euro spec bikes dont have the clutch operated switch in the starter interlock circuit.

ok....i've checked the starter relay and the fuse is good.
the wiring for the side stand all looks intact and good.
i'm neutral (i don't think i'd be able to push the bike without engaging the clutch if i wasn't)
anything else i can look for?

If you have a test light or a voltmeter you can troubleshoot the whole starter system
Things to check:

Make sure the engine stop switch is on Run  :icon_razz:

Neutral switch-behind the sprocket cover,trace the wire from the switch to connector,disconnect wire,
check for continuity between wire and crankcase in neutral and no continuity in gear.

Sidestand switch-behind sidestand,trace the wire and disconnect,connect between Black/White and  Green wires
check for continuity when the stand is up and no continuity when down

If these are OK then there's the sidestand relay to check....

are the neutral switch wires the ones that run to the front under the sprocket cover? (they do look like they've been pinched by the housing)
i take it those are what tells the bike that you have the clutch engaged?

The neutral switch is just above the sprocket and the wire runs back to connector behind the left cover

The switch tells the bike that it's in neutral and it's OK to start the engine  :thumb:

I'd just leave it by-passed, one less thing to go wrong. All you have to do is engage brain before starter, worked for me for years until someone thought we had to be protected from our own stupidity. As soon as something goes wrong with one of the 1000 switches, relays, cables and connectors I'm junking the whole lot and connecting the strter switch staight to the ignition.
How long before we get a bike that won't start until all your safety gear is on and you've got a note signed by both your parents saying you can go? :mad: :mad:
