Hello, I am restoring a bayou 220 here in Brazil, I have a question regarding the rear brake activated by the lever on the left side. The ex-owner connected it in place of the reverse cable and as this is incorrect, could someone show me through pictures where I correctly connect the rear brake cable? Another thing, every time you reverse, is it necessary to activate the reverse key?
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!
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!

Hello everyone! I recently purchased this quad for a mere 300.00 and it is pretty clean for the year. I bought it from a guy who bought it in a storage unit. He didn’t know anything about it. I got it home and noticed it did not have an ignition coil for the spark plug. I bought the ignition coil, a new battery, new CDI box, new starter relay, new safety neutral relay, new carb and so on... I got it to turn over, but when I pull the plug and check for spark I have nothing.. it has a non factory starter button that works when I push it and turns the engine over no matter if the key or stop switch is on or off..not sure what that’s all about, but it does turn over..just no spark at the plug. Any help would be greatly appreciated! Thanks!
Picked up a 98 Quadrunner 500 for a song. It's in rough shape, but funny enough it turned over and fired on starter fluid. Fuel lines are rotted to snot and the inlet tubes to the carb are rusty. I have a rebuild kit for the mikuni, but I'm wondering if anyone has used any of those alternatives on Ebay or Amazon that say they fit?
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
Hi i bought my first atv last week, mostly for plowing. its a 94 yamaha big bear 350 4x4, with plow, new front axles, carb rebuild and some other stuff for $900. in todays prices, i think it was a pretty good deal. I plan on tearing it down and doing a semi restoration in the summer. its been clearly neglected so i suspect i will need to do a fair amount.
1. parts and manuals, so far i know it needs front shocks, tie rods, brakes, cables, lots of small stuff, whats your guys favorite online atv parts store? where can i find a good repair manual?
2 - starts and drives great, shifts a bit hard? not sure whats normal because i dont have a point of referance. i have to almost lean back in the seat and lever my foot up to get it to shift, seems like there is either alot of play in something (shift lever itself is tight) or there is a long travel, or it just dosent want to shift. also the hi / low / reverse lever needs to go past the gate a bit to actually shift into gear, and seems to need me to shift into nutral before shifting into reverse (not sure what your supposed to do). also wondering a bit about the history of the machine, because the plastics have a slot for a dash mounted shifter, but the one on it is a gated shifter right above the pull starter.
3. seat and plastics repair, seat is quite torn up with a seat cover over it, plastics are pretty cracked up, these items i havent found replacements for for any reasonable price, i dont care a whole lot about asthetics but whats the best way to functionally repair these things? is there reasonably priced replacements somewhere? i plan to bedline the whole thing after im done.
4. there was no title, but i did get a bill of sale, will it be difficult to get it titled / registered? (im in mn)
thanks in advance for your help, looking forward to being part of the community
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.
