i know youv all heard this before ,bike was sitting for a week , went out to go a ride and would not start , it did try to turn but then the click from the starter relay is now all i get , iv done searches and cheked the following

charged battery put it in same click from relay
tried spare battery after full charge put in in, click from relay
tried jump leads from car still one click from relay
bridged starter relay with screwdriver starter tries to turn then stops
connectec diag wires the reading says diag 1
battery is reading 12.6 volts before i hit the start button and drops to 12 volts
tried to bump start it , hopless
cleaned battery terminals

do you think the relay is fecked ?
where is the earth wire on the rear cylnder iv not checket that ?

bike has run fine never had any probs till now typical because were having great dry spell over here and im wanting to go out a blast

any help will be greatly welcome

thanks

Anything on the display when you try and crank the engine - notably a "NO START" message?

Checked the tip-over switch? (you'll have moved this if you took the battery out to charge it) - could be battery was dead at first, now it's charged the tip-over switch is in upside down?

Killswitch? Maybe knocked it and not noticed?

Whether the relay is gone or not, shorting over the relay should have started the bike, so I'd be surprised if this is the culprit (or sole culprit, anyway)

When you say "it tries to turn, then stops" - either the battery doesn't have enough charge to keep throwing the starter, or something mechanical is going on (failed starter?)

The likely candidate is the relay. I had one go too. I hear there is yamaha replacement that constitutes an upgrade. You can probably search for the info.

the last time i had a flat battery the dash would keep resetting and i would here several clicks , but now when i press the start nothing hapens to the display , the neutra light might go a wee bit dim thats all when the relay clicks once only

I seem to remember that kill swicth on means you don't even get a relay click, I would guess that tip over would do the same...

if you've bridged the soliniod and the starter try's to turn then stops then it's either the starter or battery.a knackered battery can still show 12 volts, you need to see what amps it's kicking out.

This doesn't sound so different to something I experienced a few weeks back.

I went over to visit woodbutcher and stopped in a lay-bye to ring him to check he was at home. Turned the bike off to hear the phone.

When I came to re-start, it was having none of it - absolutely nothing.
Usual checks - immobiliser ... neutral ... kill switch ..... nothing - just wouldn't turn over.

Time to clutch at straws ... now I have bump-started it a couple of times when I've turned the fast-idle off too early and it's died when coming to a junction ... careful clutch dropping in 2nd or 3rd has done it. Let's try bumping it .... but, of course, running and pushing bumping is not so easy and I didn't manage to get it going.

So I thumbed the starter again and it started straight away.

Rode the half mile to Woodbutcher's and when it was time to leave it started fine again - and has done since. It certainly can't have been a flat battery.

Similar happened to me once before too.

Now I can't say that I'm sure that I really understand just what's happening but I wonder whether the pistons have stopped at a point where the starter motor can't overcome the initial compression? ....or something.

I've never posted up about this before as I don't really understand what happened and it's been fine since

I blame E.T.

Nah, he was caught in an anomaly in the space-time continuum; in a parallel universe the bike started fine.

the gr33k from AF! said that the piston might be at tdc to d-rider , so im charging the spare battery fully for tommorow and ill try to rock the bike in gear to move the piston , or take the spark plugs out , cheers

Wouldn't trying to bump-start it have moved the pistons somewhat?

Yes - that was my point

Oh dear... well in that case I'm probably wrong about it ... though I guess he's got to be right about something one day

it does'nt matter where the piston is, if the battery and starter are healthy it'll turn over. try putting a live straight to the starter with the ignition on,if it starts then work your way back.

Yeah, that was another thought that had crossed my mind ..... then I started to wonder "what if, somehow, the sprag had failed to disengage properly?"
Never looked at the design so I don't know whether that's possible though sometimes when I stop the engine there's a bit of a clunk as though something is disengaging .... which may mean that it has been stuck engaged.

Dunno really.
