carni026 Posted September 29, 2009 Report Share Posted September 29, 2009 (edited) .... my 315r just seem to have died, and i found this red stuff similar to a old air filter, under the carburator, laying over the centercase. when i backbleeded the rear brake, some of this stuff came out from the breake hose, but i bleeded it well and ignored it. now after riding for some 20 min, it went off,, i could not turn it on again, and i found more of this red filter-like stuff. Anyone has any idea what just happened? how do i fix it? ho.... i just found this in youtube i hope this solves my problem Edited September 29, 2009 by CaRnI026 Quote Link to comment Share on other sites More sharing options...
carni026 Posted September 29, 2009 Author Report Share Posted September 29, 2009 mmmm..... i opened the carb and cleaned it, it didn't look bad at all. i found that the red stuff was part of a cushioning from the rear shock. i haven't check it, but i imagine it wil be on for a while, and then go off again, or maybe it wont turn on. anyone has any ideas why it suddendly died, and i could not start it again?

tt5th Posted September 29, 2009 Report Share Posted September 29, 2009 I'd start with the the spark plug, make sure its not fouled. Then i'd check for a spark. If no spark I'd check the kill switch and then the stator. If there's a spark then i'd check the petrol is getting to the carb. I imagine the air filter is mostly clean. If it starts but only cuts out when it gets hot it could be the stator. Quote Link to comment Share on other sites More sharing options...
carni026 Posted September 30, 2009 Author Report Share Posted September 30, 2009 no spark..... whats next? what exactly will i be replacing??? Quote Link to comment Share on other sites More sharing options...
carni026 Posted September 30, 2009 Author Report Share Posted September 30, 2009 (edited) all right, i did as you told me, i checked the spark plug, looked ok, then i looked for spark's, and nothing, then the killswitch, ok too, now i dont understand, i re-checked the spark plug, and i could not make a single spark with the screwdriver in it. then i lookd around for a new spark plug cap, since i didnt find one around i put the one it had back and tried turning the bike on and it actually turned on, then i turned it off after 3 or 4 min. i took it outside and tried turning it on again but nothing. i could not turn it on again. anyone knows what my problem is? and by the way, the little hose in the carburator that goes from side to side is meant to be cut, or is it only mine?, the mechanic told me it should not have that cut in between, that i should replace that hose. but the parts manual shows it with the cut i believe. click this link to view carburator part #19 (tube, Airvent) Edited September 30, 2009 by CaRnI026 Quote Link to comment Share on other sites More sharing options...
tt5th Posted September 30, 2009 Report Share Posted September 30, 2009 Strange one, could be a knackered plug cap or a loose earth wire on the coil maybe? I'd personally change the spark plug anyway. If still no joy then you'll have to get a tester out and check the resistances on the coil and stator. And yes that hose on the carb is supposed to be cut.

Just a thought, did you just look in the carb or actually remove and clean the jets? Just thinking a blockage in your idle jet could be hard to spot by eye.

carni026 Posted October 1, 2009 Author Report Share Posted October 1, 2009 .... well i wasn't sure what i was looking for, after all it seem to be in good shape. so i opened it up and cleaned just about every jet choke hole, the hose that runs from side to side etc. exepct for the jet in the reservoir, where the floats are. i was too lazy to take the pin out and then the jet from there , if you think that might have anything to do, i could try cleaning that too. at the moment im changing the spark plug, but im no sure about the gap for it. im looking for it in the fourum. i kick the starter lever a couple of times with the spark plug off, and this black dirt flow over my face, from the cylinder head (where the sparkplug seats), the bottom of the sparkplug was all black too, is there any way to clean that or it don't matter?

tt5th Posted October 2, 2009 Report Share Posted October 2, 2009 Change that spark plug first if its all black. You can clean old ones, I use sandpaper but make sure you rinse it a lot with a light oil like wd-40 before you use it again. I dry it with tissue paper after. If the spark plug is new the gap should be fine, they are set from the factory and 100% of the time I've checked them its been right. 0.7mm if I remember correctly. If still no joy take that final jet out of the carb and clean it. Quote Link to comment Share on other sites More sharing options...
carni026 Posted October 2, 2009 Author Report Share Posted October 2, 2009 hohoho.... ea ea ea ea!!! finally its working!!!!!!! i changed the spark plug for a new one, i didnt get the correct one since they didnt have the right one, i tried it and nothing, then i went to another place and got the same one i had on(not the original) B8ES or B(something)8ES, not sure what the writing says, but its from NGK and tried it but nothing yet, then i checked all the cables and the CDi unit, because last thing i did before it stoped working was wash it with the tank off, so i poured a bucket of water on the motorcycle, later on i rechecked it and saw the kill switch was stock in... opened it up and kick it .... BRUMMM, BRUMMMMMMMMMM, BRUMMMMMMMMMMMMMMM, turn it off, and re start it and BRUMMMMMM AGAIN!!!!!, eaaaaa eaaaaa, i ammmm sooooo haaappyyy nowwww!!!! THANK YOU tt5th !!!!!!
