Bayou 400 no spark, no 12v at ignition coil

Recommended Posts

I’m working on a Kawasaki Bayou KLF400 for a family member that doesn’t have spark. I’ve already replace the ignition switch and the stator which were defective. The stator had a melted connector and one of the phase had low resistance and low VAC output. 

What I’ve figured out so far is that I’m not getting 12V to the ignition coil when I turn the key to the ON position. From what I understand, the 12V should come from the CDI. I’ve resistance tested both wires going from the CDI to the ignition coil (Green/white and black/yellow). They are fine. The only 12V coming from the ECU is on the yellow/red wire.

I don’t have the wiring diagram for the 400 but I’m working with the one for the Bayou 300 which looks pretty similar except for the wire color between the CDI and ignition coil. On the 300 diagram, the yellow/red wire goes to the ignition coil, not the black/yellow… All the other wires color match except for this one. Not sure if that’s normal?

Thanks!

Alright so wiring is correct.

So that means I should get 12VDC from the green/white wire coming out of the ignitor? I don't. Would that point to the igniter being the probrem? There 12V coming into the igniter from the ignition switch (yellow/red wire)

No, definitely not. There is no measurable voltage to coil on a CDI system and you can damage things by trying to test stuff incorrectly. A CDI cannot be tested by most people. By this I mean you need a very exclusive CDI tester, There are probably just a handful in the world. Use the service manual to measure the resistance of parts that feed the CDI, in this case it is only the pickup coil, if they are good, CDI is bad.

      Hello i have a linhai 300 of the 2004+- era. I had a cluch problem so we changed it. After changing it has a hard time to start going. When you pop it into gear and press the gas it barely drives but when it starts going about 20km/h it start driving well the acceleration is normal and everything do you have any idea of what could be the problem

      Hello 
      I have a 1994 Kawi Bayou 400 which had been running well until it sat for about a month. I left the carb dry while it was park and the temp had dropped below 0C in this time. Pulled it out last night to go for a ride and it fired up just like it should but noticed when I started to head down the road I could hold it to the bar and it didn't seem to accelerate. Lower gears weren't as noticeable but 4th and 5th it just seemed to have no acceleration and half or full throttle  made no difference. if I tried to go into 5th gear with any throttle it would stall. I turned around and just poked home very slow and it seemed to stay running but this was between 15 and 20 km/h max. 
      I have taken the carb apart and it appears to be clean and nothing stood out on inspection to have dirt or ice. Is there something I should dig more into? 
      I have checked the plug and it appears to be sooty with easily rubbed off carbon. I plan to get a new plug today and test. 
      compression with the throttle wide open is 175 psi. 
      I have opened the drain plug in the exhaust thinking there could be a mouse in the exhaust or something but no difference. 
      I do find the engine is tickity compared to my 2000 Honda but I am not sure if this is just me looking for issues or if it has always been this way. 
      If anyone has any insight I would appreciate it.
      In the last 6 months I have done new oil and filter ( mystik synthetic) 
      new Peak RPM CDI 
      I have noticed the fan comes on more often with the new CDI, could this be a program thing?

      I've recently acquired a 1995 Kawasaki Lakota KEF300A1 that seems to have a pretty slack chain. I've found an owners manual that talks about the procedure to tighten it to spec, but it mentions "inserting a bar provided in the tool kit into the axle housing and turning it upwards/downwards"... the problem is I don't have the tool kit that came originally with the ATV. Its hard to tell from the picture (and not ever having done this before), but it looks as though this "bar" may just be a pry bar/leverage tool. Is that so and I could just use a screwdriver or anything that fits into the hole? or is this a specialty tool and do you know where I can find one?
      Thanks
      -Rob
