I have a 2003 KX 250. The bike is fairly new, and has always been maintained. The bike has a 7oz. flywheel weight, and a Pro-Circuit pipe, the gearing and chain appear stock. Chain is in good condition. Now...on to the problem...
The chain seems to get VERY loose after a whole day of riding in the woods/sand (fast sandy Florida trails). I tightened it according to the book, and I keep it clean and lubed. The chain will get so loose, that it will make a 'clack' sound while riding (especially whoops and jumps). When it gets loose, I can pull a lot of links off of the rear of the sprocket with my hand. I am fairly mechanically inclined, but I cannot see any particular part that seems to be making the chain get loose (no sign of axle block movement). Is the chain really stretching that much (every ride), or is something else getting loose and loosening the chain? Is my riding style stretching the chain ? Or is something else wrong? I have heard that the stock chain is junk, is this why people say that? Help me keep a tight chain. Thanks. -Todd
