  1. @Michael Rogers If you're putting in a new valve, don't forget to lap it. The chances of the angle on the new valve matching the old head is about 0%. Might as well lap the other valve while you have it apart.
  2. I've never split the cast on a Kawasaki but I bet it's like Honda or Yamaha of the same year. Pretty straight forward with a service manual. I'd try anything once if it's cheap enough!
  3. Did it run fine and then one day not? Did you rebuild the top end and maybe get timing off a mark? What does the plug look like? Did you clean the jets out with a bit of wire or torch cleaning tips when you cleaned the carb? How does the diaphragm look on the throttle slide? Any holes in it? Does it rev to WOT in neutral but dies under load? Give us a bit more specific info to work with and I bet the group can help you find the issue.
  4. 98 I rebuilt last summer only had 2 wires as well. This guy has a really decent wiring diagram for a 220 on his video you can screenshot. I've used it a few times and it's been spot on for me.
  5. Sneak peak of what this one will look like when it's done. If you were around ATC's when the last 250r rolled off the line, you can see where this is going. Should be pretty cool.
  6. I'd say don't take anything to that shop again. It seems they were trying to throw parts at it without an actual diagnosis. That's lazy and incompetent. Glad you got it fixed though, good work.
  7. Get some left handed drill bits and good luck. When they're seized they're a bitch.
  8. I had a 98 identical to yours and it only had like 90psi of compression....but it still popped right off with the start button. Those 220's were bulletproof little utility quads. Not fast, not obscene amounts of power, but well built and extremely resilient when not maintenanced properly.
  9. Hell yeah brother, love to see progress! Start buttons are notoriously finicky because they are just a brass pop style button. Slightest dirt or corrosion and they are hit and miss. Using it again will help it clean itself out a bit.
  10. Picked this beauty up for zero dollars this weekend. It has been passed around several of my son's friends and the last kid was just tired of tinkering with it. Mostly complete 96 300FW. The pic is my boy robbing the swing arm and rear diff for his 300 for a big memorial weekend ride. Wiring is garbage at the battery, kick start doesnt work, no coil, smoked like cheech and chong when it ran last. I figure a couple hundred and a few hours and this will be ready to ride. Journey will be documented on Instagram at @martincyclellc if ya wanna follow along.
  11. If you have a micrometer and the original bushing you can just measure it and find a replacement. Like the seal above has the numbers on it; 30mm ID, 75mm OD, 10mm depth. Bearings and bushings are measured the same way.
  12. Welcome to the forum! 1. Fill it till it runs out the fill plug. 2. can't usually tell unless there is slop in them. And yes, they are a bitch to change. You have to pop the circlips and knock the caps out. It sucks. 3. I'd bet the front diff is dry because seals are dry and leaking. If you fill it up and it still makes noise after riding a bit, my next suspicion would be wheel bearings. They may be intact and tight, but that tightness may be residual rust in the bearings. I think those are sealed so there's really no way to repack, just have to replace. Axles rarely make noise other than popping. An option after filling the diff may just be to ride it and see what breaks. If it did sit for a while, it probably needs shook down good. I'm sure all kinds of stuff will pop and squeal as it settles back in to service. I have rehabbed quite a few that sat outside for years and usually I just get em running and ride it to see what breaks next. Bit by bit you work the bugs out and end up with a good ATV without a ton of money invested.
  13. When you hit the starter button do you get any audible click from the starter relay next to the battery and solenoid? If there is any audible click, i'd try holding the button down and tapping the starter lightly with a wrench. Sometimes the brushes are worn out and not contacting properly. If you have green light though and no click at all from the relay I would suspect bad relay. Relay is like $7 at Autozone in the aux lighting isle.
  14. I'd bet the brushes are bad in the starter. Try holding the start button down and giving the starter a tap with a wrench. I bet it'll pop right off. When it's warm, metal expands a bit and I bet the change in tolerances lets the brushes contact.
  15. 2 boots per axle is about as much as just buying a new axle.
  16. 400ex is generally preferred due to being a bit more simple to work on and has been in production forever with very few changes so the aftermarket is large. 450 is still a good bike though.
  17. Not sure I understand what you just tried to say.
  18. That's just a ground wire, and it's a factory crimp. If you look at the front under the bars there's a mess of 3 to 1 crimps and even a couple of spare hot and ground wires for accessory. If you're not getting fire pull starting you could always bypass the ignition and run/stop/run and see if it's a bad ignition or multi switch. Blue to ground maybe? Been a minute since I looked at that diagram. I rebuilt 2 just like that last summer that I pulled from the weeds. Good little simple ATV's. Low gearing, reliable motor. And I did the same centrifugal clutch regroove and drum smoothing on one of them. And a Kodiak. And a few others. TufDog also noticed there were no clear diagrams and made a youtube video you can pause and screenshot. This is the one I have used several times. This
  19. So it's turning over just fine with the start button. Now you have to move on and see if the spark plug actually fires a spark (or put a screwdriver in the plug boot instead of the plug and see if it will fire against the head), then on to fuel, etc.
  20. Normally that symptom is caused by timing 180 degrees out. Lucky the piston hasn't smacked a valve yet. I havent timed a Polaris but on some hondas theres a couple marks then an F timing mark and a T timing mark. Pretty common to time to the wrong mark.
  21. Good tip for future searchers of the forum. Thanks for posting!
  22. Looks like the rings are seized into the piston. Can you move them around freely? If not, then there's your compression loss. Fairly normal for a motor that has sat for a while.
  23. Good point @gillies_robert If valves aren't sealing it would also have no compression. That head doesn't look too chunky but it doesn't take but a micron to keep it from sealing.
  24. That rust line looks like its below the rings so it should be ok. It's pretty worn so you might want to check it with a bore gauge. 40 psi was probably due to a ring stuck on the piston bc thats pitiful compression. If it's in tolerance hone it a bit to give it a good crosshatch, set of good rings and I bet you get compression back.
