Check the primary side of the coil for .3 ohms. Test the stator again. After that you may have to pull the y-pipe and look for a broken piston skirt. You may not see low compression with a broken skirt.Check the ignition timing sensor for resistance also. it should be about 190. you can also unplug the main harness at the stator and try it. a bad ignition switch will cause gremlins also. are all your grounds good? The ecu ground and the rewind housing to the main frame.Sorry Mike, its a 98 zr 600 efi. I'm chasing a problem with this sled. It won't rev over 4800 rpm and it backfires like crazy if you hold the throttle open. It starts fine and will idle fine but just won't rev up. The stator was bad so i replaced that with a known good one, no change. the tss is disconnected, no change. The fuel pump is pushing about 40 psi and lots of volume. I fiddled with the tps and the best i could get is 960 ohms at idle and 4180 ohms at wot.
The spark plugs are new br9es. thet appear slightly oily but the center porcelin is staying white. There no codes flashing on the ecu. I've checked just about everything i could check on this machine and can't seem to find the culprit. Do you have any input on this?
Start a foum war...it is Sunday and eveyrone is bored. General rule of thumb is the triple triggers were 175 ohms and the twins were 90. The twins are listed at 190 ohms in the manual but the manual is wrong. You have a rewound stator...whether it is a complete aftermarket unit or just the ignition coils were rewound I don't know. Either way...the ignition coils are bad on it.I don't mean to start a forum war but is the pick up stator supposed to be 190 ohms or 190 ohms? Blaine, the stator came off of a good running sled that blew up. but I don't think its an oem stator, as it has green epoxy on the ends of all the coils. Would that explain the slightly high readings on the low speed coil? Thanks for all your help guys, I'd be in the dark if it wasn't for this forum and all your help.
