First thanks for any help guys, new to the forums and it's gotten me this far. I bought a 2001 bear tracker 250 for my family to get around the dirt bikes races. It wasn't running right and had a high idle. Previous owner thought it was a carb problem, so he ordered a new Zoom carb and new intake boot, but it still had the same high idle. ( I believe he had the throttle cable adjusted wrong, because it idled fine when I put it back together) So I tore down and cleaned the stock carb, and it started up and idled fine, but needed to have the choke 1/2 out to run. I swapped to the new zoom carb and had the same issue. Choke half out bike ran ok. I played with the needle and the pilot screw with no change. ( bike did seem to be running rich though, but didn't get better when I tightened pilot screw or raised meddle) I Took it to the races and once I started bouncing around in the cattle fields the quad started cutting out real bad. It would barely run. Sometimes it would run with choke off, sometimes choke 1/2, sometime choke full. I cleaned carb again, checked float level, and boots, no change still wouldn't run. Then suddenly it started running ok again. This makes me believe it's an electrical issue rather then carb. I know there's no air leak, it's been checked, both carbs are clean( I've swapped them out a couple times, it starts up immediately and usually idles fine. But then bogs down/ or stutters under throttle. I saw the post on the guy who disconnected his rectifier and reconnected and suddenly it started working again, which lead me to believe it may be electrical and not carb. So any advice on what I should check? Any way to test the CDI or rectifier? Once again, I appreciate your help.

2001 bayou 220 KLF220A
Need some help putting a new ignition switch on this thing. I'm not finding homes for all the wires. I can hook up the white wire and brown wire, But the switch has a B/W and Solid Yellow wire i can't find a home for, and there aren't any more wires in the vicinity from the harness that match this, except one red wire with a double female end crimped on, and a few B/Y grounds. None of the wiring diagrams i've founder or have been given match.
I'm also wondering if i have the wrong switch? some switches appear to have 4 wires and other just 2, the Brown wire and a White wire.
I'm at a loss here. Thanks.

Hi folks, a little disparity brought me to this forum. To set the stage, I'm a 35 auto tech in the industry 37 years now. Licensed motorcycle tech also, 20+ years. I race superbike and motocross. Always done most of my own standard work (outside of specific race machine works) including building my own race bike engines. Now that skills are out of the way, onwards and upwards.
Helping a neighbor with his old quest 500, right front axle seal leak. Well, looks like everything else - right? Wrong! Initially I noticed the CV joint was lacking large lands to place prybars on to pop it out, rather a thin shield like ring very close to the diff seal. Knowing the ring appeared quite delicate, I only pried gently and the CV popped out. However this is where things get weird. Came out only around 7-9mm then hung up again, felt like the clip was catching inside the diff. So spun and pulled, spun and pulled until I was blue in the face but no success getting it out. Also while it was out, I could see that the delicate ring around the outer circumference of the joint was actually the sealing surface where the seal contacts, instead of the norm where the seal rubs inside the diff much deeper and stays cleaner. I've never seen a joint like this, also the service manuals photos which apply to 650 also reflected a standard joint I am accustomed to rather than this one I was fighting with. Rather than break something in the diff, I decided to stop while I was ahead and reassemble the machine before something broke. (The joint would pop in and out of place easy enough, just wouldn't slide out further than 7-9mm). While the joint was a little out and sealing surface exposed, I cleaned the seal and sealing surfaces clean as possible before putting back together. Seems to be holding for now, but eventually I'm sure the leak will come back. Any thoughts as to why that CV joint just refused to come all the way out?
