Hey so i have a 1990 bayou 220, and its missing the wiring harness so i went online and bought a bayou 300 wiring harness by mistake. Will it work if i use the 220’s cdi box and ignition coil?
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!

Are these motors the same?
Just was given a 220 bayou, turns over and was wired by a crazy mouse on drugs helped by a committee of politicians taking advice from lil green folk from Mars! This is going to be fun. Claimed the stator was bad. My other project is an old lakota, died driving with no spark and has sat for a bit due to building a house n life! In other words,I may need lots of advice!
I've inherited a 1995 Lakota 300... it has the knob in the center of the handbar to twist to go into reverse, but I've notice when downshifting, you don't have to have the knob turned, it will shift right past neutral and into reverse which is a little dicey if not all the way stopped. I followed the linkage back and twisting the knob seems to actuate the lever on the outside of the trans, the internals just don't seem to care about this.
What is the likely problem and how back is it to get to? I've never been inside of one of these transmissions.
Anyone know where to locate these, or generics? The generics I seem to find have the mount on the wrong side versus the hose outlet. PITA!
Also, is the rear master cylinder rebuild kit any good?
hi all first post just found forum and the manuals / wiring diagram BIG THANK YOU
im struggling to find the vin number on my frame? I m told left side of frame , lower, nr. in front of the gear pedal ?? haven't found it yet , is it numbers stamped on the frame or a commission plate ??
main prob. no spark no power to coil , off to study the wiring info I've just found
thanks again. tom
Hey there all,
First off thanks for the board. My Bayou 220 has survived 3 teenagers and is on its 4th now. Up until recently it has been a virtual tank....until I decided to fix it;)
Noticed some smoking from the engine block (not exhaust) so figured it was time for a quick top end rebuild. Now that I have it all back together, it fails to start. I've pulled the starter rope until my arm is tired.
So I will be as detailed as possible and hopefully get some help.
-New Head gasket
-New Valve seals
-New piston (standard)
-New rings (standard)
-All new seals
-Cleaned up head and valves (didn't do any resurfacing, as it all cleaned up pretty easy)
-All torqued to spec
-Piston ring gaps all checked out
-Valve clearances (Intake: .18mm, Exhaust .20mm). Not too tight, not too loose.
-Engine IS making decent compression
-DO have spark
-Will fire for a split second if I drop some gas in the spark plug hole and pull start. Will NOT from carb and or intake valve.
So I followed the guide of: TDC
-Flywheel aligns on the “T” mark on the engine site hole
-Cam gear mark aligned with the cover mark
Seeing as this is my first time doing a top end rebuild on an ATV. Here are my questions and concerns:
-I didn't realize (dummy me) that there are 2 TDC's. 1- Compression, 1-Exhaust.
How do I know if I'm on the right one?
-Does the cam need to be aligned a certain way when put back in? I just aligned the cam gear dimple with the cam and put it in. No alignment.
Thanks ahead of time. I feel like I'm 90% there, but I'm missing an important step for completion.
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?
