Alright heres the story i own a 1993 Suzuki across the bike up until a few months ago was running perfectly, I had just redone the carbs and it was running great so i decided id wash it after i had washed the bike quite lightly aswell didnt put water near the exhaust or any major components but all i could get from the ignition was a light buzzing i thought maybe water got in one of the wire's plugs so i left the bike for over three weeks while on holidays, After coming back the bike was dead so charged the battery put it back in but nothing not even a noise no lights or anything,After replacing the battery still no luck so far have replaced the regulator-rectifier thinking maybe that was the problem but no the bike will however start when jumped from a car battery but will backfire, smells like its running rich and has fouled two sets of new spark plugs so its not there my last thought is its the Electronic ignition box but i would however like to know if anyone has opinions on what it may be as i have spent alot of money so far working on it so if anyone has any idea's what it could be i will take any information at the moment Thankyou.
Hmm this is a tricky one. What I don't understand is why it starts from a car jump start but not from the battery, your battery might be buggered. May want to test that a little more closely: That won't help your running circumstances though. The fact it runs means you're getting spark and fuel, even if it runs terribly. Having not changed anything else, I wonder if you have a short somewhere. I have never heard of CDI's failing slowly or partially (others may have had different experiences so happy to be corrected), I think they're a "dead" fail ie when they have have a problem they simply don't work. I would be inspecting the loom around the dash and looking for any shorts/damage/melted wires and inspecting all the plugs. My CBF runs without the dash connected so it may not be necessary for it to start up. Check your fuses as well... sometimes the simple things can fix the strangest problems...
As above ... water may have shorted something when u tried to restart after the wash. Was the replacement battery new? Run these tests http://2fiftycc.com/index.php?threads/how-do-i-test-my-12-volt-battery-and-charging-system.1794/ And check your leads are correct http://2fiftycc.com/index.php?threa...eads-spark-plug-configuration-inline-4s.8176/ http://2fiftycc.com/index.php?threads/trim-your-spark-leads.8032/
Acrosses need a really good battery, how are you starting it ? Should be full choke and no throttlle. As for the plugs, maybe whip the carbs of and make sure your 4 slow jets are clean and you can see a pin ***** of light through them. Also check your airbox is on properly
Yes joker it is a tricky one, as for the battery its a brand new battery from the suzuki bike shop in my town specified for the suzuki across so i dont see a problem there, Also the leads on the bike are new aswell, I have looked at most of the wiring harness and to what i can see its in good condition but i will however do a second more thorough check also checking the fuses, And in reply to kiffsta the bike wont kick even on full charge its like as if the bike is draining the battery somewhere really fast and without the help of an extra power sauce nothing comes on no lights nothing Ill get back to you guys once ive checked the wiring again and fuses i may just luck out and find something
Hey it might be worth checking the condition of the solinoid in the starter motor, also with the starter solinoid that has the neg and pos leads attached to it grab a screw driver and bridge both terminal pegs "On the Solenoid" with bike battery connected and see if you get a good strong spark and if the bike winds over, if you get a good strong spark but no winding over I would be checking the electrical side of your starter motor, if there is no strong spark then it is a lack of power issue I would say. This is one of those situations where you can check a hell of a lot and come up trumps or get lucky by finding a bad earth or a power jump somewhere
I have learnt the hard way mind you that going out and buying a portable jump pack can be very very handy when it comes to starting troublesome motors It only took 4 or so batteries dropping cells and hours and hours of wasted time charging batteries via a trickle charge battery charging unit
Well after checkin the wires i have had no luck finding a break or even a pinched wire so its elsewhere unfortuantly and yes when jumpstarting i just jump it off the battery without the car being on the bike will start and run (when jumped) i can ride it around it does however feel like theres power loss and has that smell of unburnt fuel and the popping/backfiring also not sure if i mentioned but the rpm tacho jumps around like crazy but the bike doesnt rev or over rev so im pretty sure this is just an electrical problem just a matter of finding where thats where im at so far...Also changed all fuses just to make sure it wasnt them but no luck still, Can a broken stator cause these electrical problems or is it the same as the cdi if it is broken it just wont work?
my tacho was jumping around and bike wouldnt rev when battery terminals were dirty the day i bought it. i also had to use a jump starter to get it to fire. after cleaning and tightening the connection went fine. just something to check.
Ok so ive spent the past few days troubleshooting everything and ive finally solved and fixed the problem, The CDI had built up corrosion on the terminals causing a short which i presume was causing the bike to backfire and lose power i also found that a few of my relays had 'Looked ok" but were actually doing nothing so ive replaced those and the cdi and finally have the bike back to how it was before and its running better then it ever has thanks everyone for your suggestions and help
Great news its fixed, feel like an overnight ride with the lads ? http://www.2fiftycc.com/index.php?threads/nsw-qld-meet-and-greet-2016.8455/
Id love to but sadly working in the hospitality industry april is a big month for us but i will keep my eye out for the next one for sure thanks kiffsta!
