Yes sir, running great for now anyway

Sorry it took so long to update this, I am getting lazier as I get older... This bike was bought with the owner saying it had jumped timing. With the awesome help on here this is what I found and did to fix it. No compression. Due to the timing jump it bent the intake valve and the rings were worn out. Replaced valve, honed cylinder and installed new rings. No spark issue, replaced CDI box and ignition coil.Installed new spark plug. Other items replaced as identified. Starter solenoid, could jump across the terminals to start. Carburetor replace DC, tried cleaning the old one but still didn't work right. $23 carb $7 ignition coil $23 cdi $7 starter solenoid $3 spark plug $ 40 ring and gasket kit $16 valve $10 stator cover gasket (nothing wrong just opened it up to see what was in there) $20 oil change. Rounded up on the prices. Hope this might help someone. And, I appreciate the help.

Thanks Mark. I will add that to my notes.

Anyone know if the stator cover gasket needs sealant? Thanks

Thanks, I should have got it, someone else snatched it up

Sorry it took so long. I have a 2000 bayou. Just white and brown from the key switch. On mine the white wire comes from the 20A fuse to the keyswitch. Keyswitch turned on routes power through the brown wire to the starter relay. When the starter button is pushed it closes the circuit to the starter relay and the black wire from the through side of the starter relay is jumped through the engine on /off switch through the red /yellow wire to the CDI which then distributes it to the starter.

Glad to hear of your success. I'm waiting on my valve to arrive today to see if mine will start once I put it all back together.

I will do some looking on mine today and try to let youblnownhow the wire run.

Anyone ever replaced the shifter shaft on one? Not sure on the year but assuming it is in the late 90's. Is it a huge task, splitting the case etc... thinking about buying it as my next project. Thanks

I believe the black and yellow goes to the ignition coil and splits off to lights. I had issues with no fire and was able to trace the diagram to find that the green and white wire from the cdi to the ignition coil had no voltage. Good luck, hope any of that helps. One more note. Black and yellow also goes to the CDI box and looks like it is a ground.

I believe you are right that the black and yellow wire should go to that plug. Not sure if the splice is factory or not, mine doesn't have a splice but it is a 2000 Bayou 220. Here is a pic of my plug.

They are moving freely. Could they have broken loose when removing the cylinder?

Thanks guys. Here are some pictures of the piston and rod.

What signs would I look for on burning oil? I bought it not running and the guy said he didn't know anything about it. I wanted a challenge and it was a good one to start with. Thanks for the help

Thanks for the response. That will be my next step.
