......coming from me that's a bit rich i know, but....

had a bloke in with a nice '04 650. mains all chewed up, ignition stator ripped out the end cover and the wires ripped off, bit ofgraunching but nothing daft. rebuilt it, runs and starts great on the kickstart. winds over very quick but will not catch on the leccy boot. no interest at all! had the wires proffesionally soldered back on.

all i can see is that there is decent compression because he gets it stuck on compression while i just paddle it like a 2T. as i say; starts first time.

anyone any experience of some silly little mistake that has stopped it starting on the button?

regards

RE: won

you say it turns over fast on the button? i know on my 650, the idle has to be a bit high to estart with my jetting so that the mixture is close. it kicks first time everytime tho, no matter what the idle level.

Hi Taffy,

Just to verify what Ned has said, leave the plug in remove the plug cap and see if it sparks from the lead to the head off the lecky start, if so mixure, if not damaged stator.

Regards

Sparks.

RE: Re: RE: Re: won

NICE, but no one has comfirmed spark when winding on the button! if for example the coil is being suplied a double pos+ on both sides of the primary winding you will have no spark this second pos+ could be a back feed from somewhere originating at your start button and considering the engine has just lunched itself means it been out, the stator has been "repaired". why discount the fact of simple human error, everyone does it!!!!! not to mention it starts fine on the kick but not on the button it winds over great though and wiring has just been played with i'd say look there first! eg i just yest delivered a new blast hole drill to rio tinto here in west aus we had no auto down hole feed after going over and after i checked hydraulic pressures and solenoid currents i found a nut had been left off a BUS bar in the main electrical junction box SIMPLE HUMAN ERROR costing us 2 hrs down time @ 30 000 bucks an hr same drill i also found the TEREX boys in the states had the air control circuit wired incorrectly meaning the reciever tank was building to 500psi on start up should be 180, i'm not saying the problem is def electrical all im saying is dont discount the stupid stuff man.
cheers boys

RE: Re: RE: Re: won

i confess that i didn't check the spark winding the engine over.

so the lads at the auro electrical shop rewired the kokusan stator, wonder if the wiring could be done wrong in such a way to only affect spark during winding? added to that the wiring finishes on the wrong side of the stator and has to be fed across and through the coils to leave the unit.

as for wires under the tank - i checked these were right against the book. maybe someone can figure out how i might have wired up to screw with the coil wires? i'd rather eat humble pie and learn something than say "did that, did that!!!"

RE: Re: RE: Re: won

hey man been thinkin bout it, disconnect ur start signal wire to ur starter and start the bike on the kick start and by rights when running it should not make a difference if u hit the button and the bike stalls you know u have problems in that circuit
 
RE: Re: RE: Re: won

sorry re word that if you hit the button it shouldnt stall if it does theres issues in the start circuit wiring

RE: Re: RE: Re: won

i didn't make it clear jusso sorry but i let the customer take it. the way i saw it, i had checked everything through and i never heard it run beofre it came in. no gaurantees that it did. but the least i can do is offer some help to him. i'll go look at the wiring diagram.

i undertsand fully what you're saying but i'll need to check the wiring diagram to tell the bloke which wire to pull.

regards

RE: Re: RE: Re: won

Maybe a quick call to the people who wound it just to confirm it is as it should have been ? and if it was done different whether it would make any difference ?
sorry but i cant help technically

i agree with the coil issue and have reservations on workmanship although given that the wires exited the wrong side of the coil i probably wouldve given it to the sparky in question and said fix ya **** mate!!! it MAY all come down to HUMAN ERROR after all hey STOVE GUY, although it may not.
some times we sit and listen to others whether you think they have a clue or not, it avoids not just to appear stupid but to open ones mouth and remove all doubt that can be plain embarressing.

RE: Re: RE: Re: won

well boys it's cured!

all thanks to little word from paul at HTM motorcycles at ballamena in N.I.

paul found the pick up on a bike he had too far away from the flywheel. called the customer up here in question and as he had the day off he went out and adjusted it closer and straighter. then he "played the music" as he called me with the great news!

i haven't checked the gap and rules etc yet but keiran is looking into it for his. so maybe he'll let us know. can keiran make it 3 out of 3 in one week?

just to remind you all that it looked ok but had taken a whack when the R/H main went.

regards

RE: Re: RE: Re: won

The gap between rotor and pulse generator should be set to 0.75mm but I'm not sure how you adjust it closer or further away. Mine seems more of the sprague problem but I will investigate this too as it's easy enough to look at.
