Keiran95 Posted June 9, 2012 Posted June 9, 2012 Okay so i took my bike out for a ride the other day & i needed a pee so turned the bike of on the ignotion, went for a pee went to ride of again and the bike just wouldnt start of the button, i checked i had fuel, the fuel tap was on, the kill switch ect and still no joy so after a few minutes of pissing about i decided to try and pump start it and it started straight away! so while it was working i headed home the bike ran perfect after i got it started but then i decided to go out again later that day and it just died on me as if i had ran out of fuel but i know for a fact i had a full tank of petrol, but it seemed like it was dieing then running okay then dieing again for example (NO power,POWER,NO power,POWER!,No power) Now i have thought about it, when i went to take my bike out for a spin it would usually idle in neutral with no problems what so ever but that day it wouldnt it would cut out everytime i left it in neutral with no revs idleing.. i took my bike to a friend that knows what he is doing and we stripped the carb down to check if there was a blockage and it seemed to be fine. he did manage to get it started from jump leads of his car but as soon as he took the leads of it died again. i am posting here in hope that someone can help me because i have no idea, i am currently bidding on a whole new igniting wiring harness with a CDI and stuff hopefully that will sort it as my mate seems to think it is the CDI although i havent been back to him just yet with my haynes because he is on holiday til sunday, Thanks for reading, i appreciate all help that you can give Keiran
Moderator Airhead Posted June 9, 2012 Moderator Posted June 9, 2012 check your sidestand switch check it's appearance, tightness, connections and if you have a multimeter check it's function...and wiggle it about to make sure it doesnt affect the reading! Spray it with WD40 pehaps you can try bypassing it by disconnecting it and bridging out the connectors on the loom, if the bike works now you need a new stand switch and i am NOT recommending you should ride with it disconnected until you get another, that one is up to you
2 Wheels Posted June 9, 2012 Posted June 9, 2012 Why do you think its the CDI,,,,,sur didnt the bike fun fine before this happened. Charge the battery and turn up the idle screw just a little,,,,,,that would by my fisrt thaughts. What revs did it idle at before??
Ryan09 Posted June 10, 2012 Posted June 10, 2012 If it works with jump leads attatched thats surely pointing towards the battery? Batteries can just all of a sudden die, its weird and annoying but they can lose a cell or something (cant remember the technical term) Check the rectifier as well, make sure the leads have good contact and no corrosion around them. The cdi sounds fine though. Youre better off finding the problem before spending money and hoping. With DT's its usually something simple.
Keiran95 Posted June 10, 2012 Author Posted June 10, 2012 thank you all for replying, i am going to go and have a play with the side stand switch and see if it will start, my friend said that it doesnt seem to be sparking, i guess that the sidestand switch would stop this from happening because it doesnt want you to ride away with the stand down?
Ryan09 Posted June 10, 2012 Posted June 10, 2012 The stand switch could be faulty i guess but i thought it may have started at least? Its simple to bypass so its worth a try. But why did the bike start with jump leads attatched?
Keiran95 Posted June 14, 2012 Author Posted June 14, 2012 its beyond me, i'm really getting annoyed with it! coming seriously close to just selling it as it is... my mate has tested the sidestand switch with a multimeter and he said it isn't that so i am waiting for the new ignition wiring harness to come along with a rectifer and CDI hopefully this will sort it, ifnot get a coil????
2 Wheels Posted June 14, 2012 Posted June 14, 2012 The bike should start with side stand down,,,provided the bike is not in gear. Whats the story now,,,, what is the bike trying to do when you try to start it,,,,,what sounds ???? Is there no spark at the plug when its out and earthed on the head ???? Have you checked the kill switch for loose or coroded wires ??? Is there any clicking coming from anywhere on the bike,,,eg. starter or little white neutrel bok at back of bike ??? When you hit the start button what happens ! nothing or does it turn over ??? Does the plug get wet when its turning over but not starting ??? If ya have no spark, start at the plug and work backwords, all the way to the coil. Is everything else on the bike working when the ignition is on ??? lights,, indicators,, horn,, speedo lights ???
Keiran95 Posted June 14, 2012 Author Posted June 14, 2012 (edited) When i hit the button it makes the correct noises it just doesn't start, its turning over but just wont go i have checked for a spark with it earthed to the exhaust and it doesn't seem to spark the lights on the dash will light up like normal but the indicators have never worked but the horn & speedo lights & lights work unsure on the plug getting wet or not i'll check very soon for you and get back to you i really appreciate the help by the way guys, i have a very short temper and dont like it when things go wrong lol Edited June 14, 2012 by Keiran95

Did you try a plug that you KNOW is working ???
Moderator Airhead Posted June 14, 2012 Moderator Posted June 14, 2012 Have you ever had the magneto rotor off? If so did you torque the nut up to the recommended specification? A rotor nut not torqued up properly will shear the woodruff key and render the bike sparkless!
Keiran95 Posted June 14, 2012 Author Posted June 14, 2012 i have never had the magneto rotor off and i dont have a brandnew plug but i have a few in my garage that i have ended up with over the years and the one that was in it when it broke down on me just checked if the plug, its getting wet running out of ideas!!!
Moderator Airhead Posted June 14, 2012 Moderator Posted June 14, 2012 seems you have a lot of luck keiran and all of it bad! did you check the resistances of the ignition coil, are they right?

And, is it gettin yet ??? What about spark with plug earthed ??? Stick in a few of them plugs ya have there and try for spark !!! EDIT: sorry miss read your post,,,, it is gettin yet

Ryan09 Posted June 14, 2012 Posted June 14, 2012 Check all the simple stuff, try starting it again with the jump leads to see if it will fire up again. Could be battery/rectifier.
flyday58 Posted June 15, 2012 Posted June 15, 2012 Not having these on the opposing side of the Big Water, am unfamiliar but one post said it started with a jump from a car battery but died when disconnected from same. Does this use a magneto or an alternator/generator? Sounds like the latter from the posts, and if so, I would lean heavily toward battery and/or alternator. Especially since you were able to pump-start it to get it home - sounds like the battery had just enough left to limp home on and then gave up. Have you checked the battery voltage?
Keiran95 Posted June 15, 2012 Author Posted June 15, 2012 The battery is near to dead at the moment due me not able to get the bike running & all the attempts i have made to get it started, still no luck at the moment for me
Paullaith Posted June 19, 2012 Posted June 19, 2012 Did you take the magneto cover off to make sure its spinning? Sounds like mine and my woodruff key has broke just waiting on a new one.
AndyDtr08 Posted June 20, 2012 Posted June 20, 2012 Connect up the jump leads again and try and start it. Sounds like battery to me. Could be battery and just that it's flooding when you're trying to start it. Once you've tried it and it doesnt stard. Take the plug out and heat/dry it over the stove.
