Hi all.
New here. Took my bike out Friday night, filled her up w gas, all was well. Came home later, put her away in garage for the night. Tried to fire her up the next day, and Nothing!!! Can anyone recommend what i should be checking/fixing/trying. Or a possible cause of the problem? Otherwise, I was thinking of parting her out on Ebay. Any and all help would be greatly appreciated. When I got her, I had no idea that there was such a dedicated following to the SR's.

Pull the plug and see what it looks like, see if you have spark when you kick it over. Then drain the float bowl and let it refill, see if you collected some water or something. That will give you a start.

Hi Johnnyjs1. Sorry to hear you are having difficulties. You will need to do some investigation to help determine what system is not functioning. You have to go in armed with the rule that you require three things to have a running engine. 1: Compression 2: Fuel 3: Spark You will need to do some basic tests to determine what is missing. Check for good compression. If you have a compression tester, remove the plug and check it out. Try to use a thread in type comp. tester and not the hold over the hole type. Not too accurate, and hard to do if you are alone. If o.k., then on to spark. You may require a second set of eyes for this. Remove your plug, install it back into the cap and ground it to the engine. Kick over the engine, by foot if you have help to watch the plug or by hand if you are alone. With the plug out you should be able to do it by hand without too much injury. The motor should be rolled over reasonably fast enough, and try to see if you are producing good spark. If not, pull up the manual in the link below and search through it for stator spec's. Perform the tests that should be outlined in the ignition or electrical section pertaining to the stator. If you have spark, check for fuel flow. Make sure your fuel shut off is in the "on" position. This will stop fuel flow if the engine is off. Remove the fuel line from the carb and hold over a little cup or something. Turn the fuel shut off to "pri" and see if fuel will flow freely from the line. If it does, turn the tap back so you don't dump too much fuel all over. With your findings, you should have an idea what area will be the problem. Report back as you can. Here is the manual link: www.slash5.net/sr500.htmltalk to you soon, G Man |

got a chance yesterday to make sure gas flow was ok. Check- all ok on that front.  . Today gonna see if there is a spark. Keepin my fingers and toes crossed. Just seems odd to me that the night before all was ok, no sign of ANY problems whatsoever. I dont want to spend a ton of money to get it going, since i bought "her" for only $250.00usd only has 5,800 miles. I'll check spark and report back. thanks for taking the time to give me a hand G Man ;D much appreciated!!!! |

Uh, did you check the fuse? Easy to forget about that, it's by the battery. Blown fuse, no ignition.

Ok, I'm gettin pretty frustrated with Maggie (named my bike ;D). Some one told me to check the condensor, but i cant get the flywheel off. Is there a way to do this without a flywheel puller? And is it possible that that could be the problem? I checked for a spark last night, and of course......nothing. Practically dismantled the bike to the frame. Thinking now might be a good time to part her out on Ebay since most of the parts are already off  . |

Hallo as gman said, first check your stator with an ohmmeter  if this is oke you should have a spark if not remove the sparkplugcap and try again, if there is a spark your cap is gone.if there is no spark,check your ignition coil 0.98ohm prim, 12kohm sec. if this is oke, it might be your cdi-unit, you can go to your local yamdealer to check this unit.you do not have to pull your flywheel off for all of this. if one of the measurements on the stator fails you might have to replace one of the coils or have a rewind. there is no condenser like on points ignition. if your stator is gone pull it off with a flywheelpuller or else you will damage your stator, puller will cost you about 8$usd, a ultrasound cleaning of your carb won`t hurt:) good luck ps killswitch oke? |

Johnny,
Do not part this bike out on Ebay.
Here is what you have to do.
Get out of your garage and onto your computer.
Bring up the on-line manual for which GMan put a link on this thread. Print out all the bits that look relevant.
Get a six pack of nice cold beer, take the beer and printouts back out to your garage. Find yourself a nice 5 gallon drum, put it where you a have a comfortable view of your bike, sit down, crack a beer and read the printout. You can ID the parts as you go because you are sitting right there on your oil drum.
You will learn some interesting things - for example sr500s don't have condensors under the flywheel, and the stator can be checked with an ohmmeter without taking of the flywheel.
Its just a matter of checking everything, including taking a good look at the wiring diagram and making sure your wiring looks to be right.
While you are doing that you will be able to see where the kill switch comes into it, and you should find away to eliminate it from your enquiries.
Don't give up, just try to go through it all systematically.
i.e. Does it spark? No? Fuse OK? Battery reading over 12 volts? (Actually my bike ran the other day with no battery at all.) Can I disconnect the kill switch, then get spark? No? Is the ignition switch knackered? Should get a light or two when you turn it on?
Can I get spark without the cap? Not that? Unplug and check the stator and coil resistances?
Go through it bit by bit. The manual really is a great guide, and covers all the possibilities. Patience is a virtue - an hour reading the manual could save you heaps of time. You won't waste anymore time looking for non-existent condensors for example. And since a lot of the tests may identify low or no cost repairs that need doing, it could see you back on the road on the cheapest SR around.
Good luck
Mick

Mik,
Thanks for givin me a good smack!!! and knockin some sense into me. i went thru the manual and did a crap load of tests to the wiring. Think i finally figured out the problem. Every test came back normal except when i got to the CDI. Got funky readings when i checked 1 wire and got no readings at all on the others. Took off the unit and am gonna take it to the dealer to have them check it out. (Just to double check before i go get another cdi). At this point i hope that it is the CDI, at least that way i will know whats wrong with the bike. If that is not the problem, then i dont know what the hell else i can do. I really, really dont want to get rid of my baby (have big plans for her over the winter). Again.....thanks for knockin some sense into me. ;D. I'm goin to dealer today and should know if its the CDI or not. I'll post as soon as I get the word from them. If it is the CDI....can i just get a hyperpak to replace it?

did you check your stator and pickupcoils disconnected from the cdi? if so you must have some readings
if your cdi is gone you can replace it by a hyperpakunit if your bike is a 2j2 or 2j4

took cdi to yamaha shop, this is what they said "Ummmm....there is no way to test that." Fricken hillbilly retards!!!! Can anyone give me the ohm readings i am supposed to get with each wire combo for the cdi? Checked the stator, got readings within the specs. checked all wiring in front and behind cdi and all seemed to be ok.
