    Hey everyone, I have high hopes that someone out there can help me. I bought a lemon of a quad and recently thought I was finally getting to the light at the end of the tunnel. I took it all apart cause of a bad head gasket. Re-used the rings and piston and honed the cylinder. I followed a...

    I have a KFX 400 that will start and idle, but when you give it gas it starts back firing badly. I have put a big bore kit in. Put new valves and shims in the head. Replaced the carburetor. Triple checked the timing. I replaced the generator, voltage regulator, and a new AGM battery. I am unsure...

    I have a 2007 KFX400. I've replaced the battery, spark plug, and cleaned the carb. Problem is, it won't start with the starter. Sometimes , if I pump the throttle for a while, I can get it to go, but it acts like it's not getting fuel. If I push start it, it will start without exception, as soon...

    My buddy has a 2001 kawasaki prairie 400 automatic 2x4. He bought it off of someone else, after the owner let it sit for about 3 months. First thing we did when he got it was clean the carb just because I knew it would be dirty and it ran but wouldn't idle. Well come to find out it was sucking...

    My cam chain/timing chain is ticking. It still has the stock tensioner. Would cleaning the tensioner do anything or is it time for a new hotcams kit? :D

    Ok so I bought this 2004 kfx 400 and it needed a new clutch cable so I put one on there and it had been working fine. Recently though the bikes clutch seemed like it was not engaging all the way and even with the clutch pulled in the bike still had some movement when u hit the gas. Now you can't...

    Is it possible to swap a 400 4x4 rear differential for 300 4x4 on a 1995. Bought a pair of 1995 bayou 400 4x4. One is complete, runs and plan on flipping it. It also came with a "parts" atv that is practically complete minus the rear differential. Seems to be difficult to find a complete...

    Alright, when I drive my kfx wide open for about 30 seconds it wants to cut out but if you let off it will drive normal again (it's like the bowl is running out of gas). Or if I ride it hard around the trails it will sputter, bog and die. It will start back up again, but only with the choke...

    On my kfx 400, I hear a kind of screeching or grinding noise.. I think it's coming from the engine area. When I shift gears, it is like a short grinding noise and when I hit the throttle more the noise gets worse. Also, sometimes when I'm stopped and take off with it revved pretty good it kind...

    So my chain is getting pretty stretched and is at the end of its tightening, so I was going to take a link or two off.... When I went to look for the link connector (or whatever you call that link of the chain that can be taken off)... I couldn't find it... So is there no link connector on kfx...

    So my 06 kfx400 has never given me a bit of trouble, over the weekend i was riding some local trails and about an hour into it cut out on a hill climb. I thought i fouled a plug so i had to run full choke and couldnt give it ANY throttle or it would die. i limped her home, replaced the plug and...
