posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

I bought this four-wheeler used for my son's birthday last week. It wasn't running when I got it but after a new battery and some tinkering it has been running for 5 days probably 8-10 hours of run time.
Today after 1 hour My son wanted to wash it, I showed him how to be careful not getting water near the engine. We were careful but after we washed it and let it dry the motor starts but the transmission slips and won't really go forward. Even if I pick the back of the four wheeler up the wheels only go forward a tiny bit. It's as if something is slipping inside. But it worked fine right before the wash.
Not sure what brand. I was told it was 90 cc's the VIN is attached. Is it 90 or 110ccs?
No air filter came with it. Using a some old stockings until I figure out what air filter to order.
My son is so bummed so I want to get it back up to speed but also teach him how to work on it.
My bear big fires up with the pull start fairly easy. My electric start worked fine but now doesn’t even try. I bought a new battery and the same. The odd thing is, when I start it up at times, the neutral or reverse light will light up at times... depending on if it’s in neutral or reverse of course... wondering if anyone knows where I should replace?

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!

Hi Everyone - Need some help.
Got a nice little 220...clean machine. wiring is a mess. I have a diagram however, the one I have has 4 wires coming from the ignition switch not 2 like mine. So, I cant trace wires properly.
There is a white one that runs to the Solenoid, and a brown wire...from the Ignition...I dont know where its supposed to go. Also, on the Solenoid, there are 3 wires..W to ignition, B to start relay and B/Y runs up to the front of the machine...and is not plugged into anything...and there isnt a "Mate" missing it. How do they plug into the 4 open shovels by the 20A fuse?
I'm pretty sure my Lights and start switch/Lights are correct.
Problem I cant get anything...new battery...cant get the start button to work, cant get any power to the lights or switches...so I know something is not grounded or..
Any advice would be greatly appreciated.

Ok, another newbie post here. Checking this stuff out in issues with lost compression. Wondering if anyone can tell by the pics and video of the cam is good, and whether you can see anything visibly with the valves and timing gear.
Any input would be a great help. Been researching youtube videos, but just not sure.
2000 Bayou 220
I could test the exhaust, it looked like it was opening, closing and seating ok, but not sure about the intake.
CAM - looks like some wear on the outer ridges on both in spots, and one lobe to me looks kind of weird, but I don't know.

Well this is my first time tearing down an ATV. Have done a little work on 2 stroke's in the past, but not much. I'm needing some help. I've got a Bayou that has lost compression. I tested it, and it was like at 40psi. I had already set the timing on it, and it does have spark fuel, etc...
My question is about the cylinder. To me it looks pretty toasted, but need some help in determining. It is a 2000 Kawasaki Bayou 220. I bought it not running, just to see if I can get it running so it has not ran since I bought it. This question is about the cylinder, and part 2 I have will be about the CAM.
Any advice / help is greatly appreciated.
Inside sleeve a line(left line) runs the length that I can feel with my fingernail. The line on the right I can't feel.
Some rust it looks like on these two pictures.
