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.

I have a kfx700. It has dual exhaust K&N air filter and a jet kit was just added last fall. I put the size recommended on the and turned them out 2.5 turns as recommended. The quad goes through its range fine but when ran at a constant speed at any point the engine bogs constantly. Any suggestions? Also, when running at a certain rpm it makes a souns similar to a slightly loose heat sheild vibrating at a high frequency or like pan likes being thrashed coming from the front. Any info is appriciated. Thanks all...
