picked up my third timberwolf 250 for my daughters. these are great light weight little quads.
have a strange one for you. the quad will NOT start in neutral. it will start in first.
if i lift up on the gear selector just enough to hear the little click (its not loud, sounds like a contact clicking, perhaps the neutral safety switch?) the light will go out, but it won't yet be in first either. that is how i have shown my daughter to start it and she can.
id like to carry out whatever repair is needed. i have the pdf of the shop manual but it doesn't really have a flow through diagram.
any help appreciated! thank you.
i need to add something. it feels like i can switch into another gear BELOW neutral.
so if i switch to neutral, i can keep pushing the gear selector, and it has another click below the neutral. the light stays on, and when i pull up into first it kind of feels like it has two positions it moves through to arrive at first.
in this thread, I want to discuss how 4-cycle atv engines work- what the different types are... how they are set up and which you prefer. To start off, are the cams on ALL atv 4-strokes powered by a cam chain? I know that on say a lawn mower or logsplitter engine, the cam is turned by the tappet, pushrods, and valve rockers. Which is better and why? Chain-driven cams or pushrod-driven cams? Are the pushrods just an old version and everything is transforming to chains or the other way around...or not at all? Just looking for some explanation, history, and downsides/upsides...
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?
Hi all, I was gifted this Bayou but she's been sitting quite some time. It won't crank using the factory start button but when I jumper the starter solenoid it cranks but there is no spark. The key has power coming in on the white wire and when turned on supplies power to the brown wire coming out.
I guess I should start with testing the pickup? I heard I may be able to jumper the wires coming from the pickup with an LED bulb and it will flash? I noticed in the manual that it should have around 110 ohms resistance so I'll check that as well. One thing I noticed was that the starter circuit relay has power on one of the black wires with the key on- this doesn't seem normal as I'm assuming the black wires are grounds? I think one of them comes from the start switch, travels through the starter circuit relay and then grounds the starter relay?
Mine is a 1991 so it has the 7 wire CDI (ignitor) and a 2 yellow wire alternator ( as opposed to the later 3 wire type ) with another 2 wires for the source coils (black & red wires ). The pickup wires are blue and black I do believe. Any help appreciated and yes I will test the pickup ASAP.
I'm trying to understand how the system works and I don't understand what the yellow / red wire from the kill switch does- I assume it gets grounded when the kill switch is "on" and therefore grounds the CDI so it can't activate the ignition coil? I noticed in the diagram that that yellow / red wire looks like it may be grounded by the ignition key switch when in the "off" position?
I also don't have 12v power at any of the wires going into the CDI- doesn't the CDI need to be powered? I also read on this forum that someone used a GM HEI module in place of the factory CDI just to test it for spark- does anyone have any info on that?
I hope I'm not missing something simple!
Here is a link to the diagram for my bike (which was posted by another user): https://www.quadcrazy.com/atvforum/topic/13742-1988-bayou-220-lost-spark/?tab=comments#comment-101193
Any help appreciated!
