HELP!!!!!!!!!!!

[wreck-n-roll rik]

What Luck I have.  First big week-end and the bike is dead, so I need some help.  1st I took it out last Sunday for a ride and ir ran great.  On Tuesday I gor a set of Kev. Clutch Plates and installed them and water pump seal/bearings and Kick Seal, Wed. put on new rear tire, sprocket and brake.  Went to start it adn it fired adn died.  I have checked everything I can think of.  Shows good spark, new plug, compression is 155+ adn yes there is gas I even went and got some strting fluid and nothing.  I took the Fly wheel cover adn checked adn everything is tight.  What else can I check?  I even pulled the bike behing the car to roll start.

Does it make any sounds of life when you try to bump start it? Sounds like it does not have a spark then. Check the connection of the spark plug and the plug wire. On my 125, the plug wire connection was damaged, so it would show a spark with the plug out. But it was not getting a spark with the plug in.

I used an inline spark checker and it showed good spark with the plug in.  It sounds like it does not have a spark at all.  Is there any way to check a coil?

You need to pull the plug out.  A piece of carbon could have got stuck in between the electrodes.  Spark plugs are cheap so I would just buy another one.  Then I would look at the fuel.  If you have water in the fuel or just bad fuel that can cause a problem.

Changed plugs - Fresh gas still same problem.  So I stripped the bike back don and started Ohming every thing.  OFF the Stator the wirees are B/W, B/Y and R/W.  According posting there should be 153-230 across the B/W & B/Y I have 190 but only for the second I cross then it goes dead.  R/W & B/Y is 7.9 to 11.9 and mine holds 10.2.  THe casing the wires are n was full of water so I'm drying out and rechecking in the a.m.  I baught a fly wheel puller today and plan to pull and clean everything...  THe coil seems okay.  HT to blacl .29 and black to ground 2.92.  Kill switch tested good.  Any thoughts on the numbers?

Was the plug wet or dry. Did you spray alittle fuel down the spark plug hole. If you have some spark then it should do something.

it sounds like you have the three things you need to run an engine. air, fuel, and spark! if you have those you should be able to run an engine right... nine times out of ten! is your spark timed? no matter how good your spark looks if it is not timed then you are F----ed, make a mark at TDC on the flywheel, using a DIAL INDICATOR in the plug hole, then attach a paper clip or a wire of some sort that will not move to the frame lined up with the mark on the flywheel. check your timing, if it is not 0 to 12 BTDC then you need to look at the flywheel and timing key, (roughly i have had a few DR. PEPPERS while working on my new ninja 600) anyone please correct me if you have some specs. if that does not work, please let me know and ill work on more troubleshooting

Your crank seals could be going bad.  They will not alow the crankcase to build pressure and send air and fuel in the right place.  You also could have a sheared flywheel key.

Have you checked your reeds? A fluttered or broken reed will give you nothing. If you have fuel, spark and compression, it could be a bad reed. I have had bike run with a bad crank seal on the flywheel side. It ran bad , but ran. The clutch side seal just puts oil into the crankcase and smokes and fouls out. If you did not touch your mag, I would not think it is ignition related, unless you unhooked something. I would still check my reeds, improper fuel metering will cause all sorts of problems, the biggest, not running .

Good Luck

Pulled the carb adn cleaned it and look in at the reed but did not pull them.  I spent the morning tinkering and re-ohming everything.  Have the B/Y to B/W intermitten ohm reading to hold it is slightly out of rang at 270 adn the manual cut off is 230.  Now for the fun stuff - I wanted to pull the the fly wheel but the prevous owner/s must have tried - the thread are all stripped out, can't even thread in the fly wheel puller in.  Now how do I get it off?  I can pick up a new stator and coil tomorrow.  Coil tested good but I plan to just replace it.

You still didn't answer one of our basic questions is the plugs wet when you pull them out? You seem to be digging deep into presumed machanical issues, when all you might have is a oil saturated, flooded crankcase.... If you have fuel, spark, and compression you should at least hear a "fart" or something... (as long as the crankcase isn't flooded)

The plug was wetish but not exsessive.  I blow the cylinder out with a match and went fump.  When I kick it it sound flat only twice has it sounded like it tried to actually fire and died.  The new plug/s look fine, not even brown tint after kicking it over several time.  Assuming that the crank was flood how would you suggest I clean it out?  In respect to the 270 B/Y to B/W and the upper cut off being 230 what do you think of that?  Still have a fly wheel I can not pull at this time and would like to be able to take it off if needed.  The crank seals are 2 years since lower end done (according to prevous owner).

Reeds are in great shape took a look at them.  Son and I just went out in the dark to take a look at the spark and there was none.  Intereasting he was advided to Spray WD40 around and throw the Flywheel by a neighbor while I was 4 wheeling this afternoon.  Would this cause my to lose spark?  I plan to pick up some contact cleaner in the a.m.

Pull the spark plug & put piston at BDC. Remove fuel line from carb and drain the bowl. Let the bike sit over night at least 12 hours, this will give the crankcase a chance to evaporate the fuel in there. After that time, do NOT hook up the fuel line yet, take a paper towel & with your finger plug the spark plug hole & kick it over 4-5 times (make sure the plug cap is in a safe place not to ignite any fuel vapors) then inspect the towel, it should be dry. If it has fuel on it the bottom end still needs to be dried out, if is dry then bring the piston to TDC & pour in some pre mixed gas (about a tablespoon full) in the plug hole, quickly install the plug & cap, kick like you mean it & hopefully it starts & runs for a moment (or at least burps). Then hook up your fuel line, turn fuel on, lay it over till it pees, kick like you mean it. If this gets it going then you probably have a bad needle seat that needs to be replaced, & until that is repaired I would turn the fuel off while the bike is running till it drained the carb. As mentioned above, you need compression, spark & fuel, sounds as if you have all but maybe too much fuel.
Keep us posted.

Bike has sat at BDC, carb cleaned up, reed inspected, filter cleaned and re-assembled, new tire, clutch plates, head and base gaskets, new brekes...  kicked it over with plug in and out and still no spark.   Re-checked ohms across everything and here is what I get.  I do have a quility digital meter from craftsmen. 
 
   1990-on
   Black/white to black/yellow       153-230  (mine  270, roughly +15%)
   White/red to black/yellow         7.9-11.9  (mine 10.9)

   Primary 1990-on: 0.26-0.36 ohms  (mine .4)
   2ndary 1990-on: 2.6-3.6 K ohms   (mine 2.9K)

   Kill switch tested good.  Before I run dowm to Dennis Kirt (about 40 miles from my house) I'm going to through a coil of a friends bike in to see if I get spark.  That slightly higher reading should not be that big of a deal and should put out some spark and most electical stuff is */- 15%.  I still would like to be able to pull the flywheel off and looking for suggestion since the threads are buggered up.  the bike is a 1995 and gave me no indications there was problems to come on last ride, in honesty it flew and starts on the 2nd or 3rd kick when cold and 1st when warmed up.  running a 168 main and 55 secondary jet, 3rd clip on the neddle, air csrew 1.5 turns out, not set to idle with a 14/49 gearing.
