    I have a 205 Kodiak 450 which I purchased new. On the last ride, I stopped for 15 minutes, got back on, the machine had only about 30% power, about 20 MPH, now it won't even go up a hill at my home that has a medium slope.. I had the carburetor rebuilt and replaced the belt. The ATV starts...

    Hello, I recently picked up a 2006 Yamaha big bear 400 4x4 for $1000. Only 2000 miles and overall good shape. I was wondering if there are any common issues I should know about. I’ve heard they’re pretty reliable things but everything has its flaws. Also, I noticed the hose for the gas cap vent...

    As the title suggests, I have an 86 moto 4 that's been giving me fits. I got it a couple months ago and it ran great then but shortly after it started having a misfire like problem. It starts up without any issues no matter the temp, but from idle to WOT it has a popping/backfire that occurs...

    My 2004 Yamaha bear tracker 250 doesn't get spark only randomly it will get spark and start and that normally will only happen in the morning. I replaced the cdi box, thinking that was the reason why it is random when it starts but that still hasn't fixed it. The spark plug is also good i tried...

    Hey everyone, I’ve been working on getting an old 98 Wolverine 350 back on the trails for a few months now. It’s been in my family for a while but it sat for a few years up until about 2 years ago. When I started fixing it up I put a new intake boot on (between carb and head) and a new carb...

    Hi All, I have a 1995 Big Bear 350. Last year it started sputtering somewhere above idle. I'd say 1/4 throttle. Doesn't seem to backfire. Just sputter. Enough that you can barely use the machine. Idle is fine though. Went through everything I could think of as well as some other stuff I got...

    I have a Champ 100 that's in great shape except for the cylinder and head. I'm trying to get it running for the kids. I've been finding it a challenge to find an replacement cylinder and head. Does anyone know if it's possible to put a 80 cylinder and head on a 100? Or does anyone have any...

    Ever since I have purchased my Warrior, I have not been able to start it without jumping the battery. When I turn the key, no power is received and the neutral light stays off. Pressing the start button does nothing. When I hook it up to jumpstart cables, the neutral light immediately turns on...
