2000 xplorer 250 bogs, stalls

[gocanesny]

I have had zero problems until 2 weeks ago. It starts and you can go 10-15mins. When it starts to heat up it will bog down, the more gas you give it to keep it running it will actually stall right out. The recoil seizes up. Once it cools you can restart it. I thought it was the gas so I put in Stabil but of course that didn't work. Im no mechanic but I noticed the fan not running, is that normal or does it only kick on when it gets hot? Could that be the problem. Please help, its making me crazy

Since this is an air cooled machine, and most don't rely on a fan to keep it cool, the air rushing over the motor as the machine moves is what primarily keeps the engine cool. My best guess is that you are running a bit lean, causing the machine to over heat. Or you have an air leak somewhere. I would try jetting a bit richer to start and see what happens. Do you have any uneven or hight idling at times?

Thanks for the info. I will try it out. Once it warms ups its definately is not idling right

You are quite welcome, good luck.

Demon, the injection hose dry rotted or melted...so i guess its safe to say we were a little lean Did some damage and are in the process of a rebuild again thanks for the info, I would have never thought to look in that area
