I've had 3 atv's in the shop with the "1 spark" problem.  2 of them were regulator/rectifier.  The other was a loose ground cable.  To check the ground, I take a pair of jumper cables and attach both clamps on one end to battery neg. and the clamps on the other end to the motor and frame.

      Hey everyone, I've been scratching my head over this for most of the day.  I bought a couple of Bayou 220's, got them running (they've both been sitting), and started tweaking and fixing small things.  One of them is mostly done, the other had an aftermarket carb on it and I've been trying to sort that out.
       
      Anyway, while adjusting the carb it died a few times, I restarted and moved on until it died and wouldn't restart.  I figured maybe I'd flooded it or something - after further attempts I realized I had no spark.  Since I have two identical machines I have many parts at my disposal.  I've swapped the CDI, spark plug and coil with no luck.  I have good resistance readings from the stator and pick up (135 and 110 respectively),  I don't have a peak voltage meter but I measure around 53VAC on the stator when cranking.  I have a 4 wire stator, not an alternator like the newer ones.  Grounds look good, I've checked the kill switch by verifying that it and the ignition switch grounds the black/yellow wire to the CDI.  I can turn the engine slowly and see the pickup short the meter as well, seems normal right?  So far everything I've checked looks the same on both machines.  I've got the service manual and wiring diagrams.  Do these readings make any sense?  I'm obviously missing something but I'm stumped.  thanks!

      Got a 99 or 2000 bayou 220. Its started making alot of noise, then the starter would spin freely. Took it apart and determined the three bolts in the starter clutch had sheared. Installed the new starter clutch and in the process, not realizing that Japanese motors turn counterclockwise, I turned the crankshaft clockwise about a half revolution so that the key holes would be on top of the crankshaft for easier installation of starter clutch. I get everything back together and try it. The pressure is so great that its very hard to pull with the pull start, the electric starter turns it over but it struggles greatly. A key issue could be this. When I engage the choke the starter will barely turn it over and you can't pull start at all because there's so much pressure. Like the back pressure cant be released once the carburetor is choked. I'm pretty sure by turning the crankshaft clockwise I screwed something up but I cannot figure out what it is. If there's anyone that can give some advice it will be greatly appreciated.

      I recently got a 98 warrior 350 that 'needed the carb adjusted' but the reality is it has no spark. I have a new spark plug, plug wire, ignition coil, battery, and cdi box. I checked continuity and took apart and inspected the starter/kill/light switch on the handle bar, and it all looks brand new and checked out. The key switch seems to be working properly, as when off, nothing works, but when switched on, lights and electric starter button work. It turns over fine, and as I just stated, all the lights work. I took all the plastics off and traced all the wires, and only one had a small cut in it, but it was only through the rubber sheathing, not the wire itself (the blue one coming from the stator). I cleaned some grounds, made sure both relays work, and still nothing. I pulled the stator cover and looked at the stator itself, and it looks great. No broken wires or connectors or anything. Still, no spark. I'm at a loss. Where do I go next? Any help is appreciated.

      I have a 1996 Kawasaki Mojave KSF250. I have no manual on it and it has a no spark issue. If anyone could give me a hand with this or would possibly have a manual would appreciate it.
