I am trying to find a diagram that shows the timing marks for either the cam shaft or ignition. Going to replace the timing chain and need to find a picture that shows the marks to do the timing. {Bud A., LA 2001 Suzuki LT250 QuadRunner (LTF250)}

We do not have a 2001 Quad Runner handy, but we can give you a description of the timing marks and instructions for cam chain installation and quad timing.

When installing a new cam chain, rotate the crank shaft to TDC . The flywheel will have indicator lines, or a T, matching a notch or line on the engine block.

Install the cam shaft with the lobes facing away from the rocker arms. Then install the cam sprocket (gear). Look for a circle or groove stamped on the cam gear to line up with the indicator on the cylinder head. Some cam sprockets have two lines that are matched up with the horizontal gasket surface of the head.

On gears without a circle, groove or 2 lines, it will have 2 bolts holding the gear to the cam. Align the center of each bolt head horizontally, matching the cylinder head gasket surface.

When installing the cam chain, or timing chain, hold the crankshaft at the T or timing mark. Put the chain over the cam sprocket. Always make sure that the side of the chain that does not have a cam chain tensioner, is pulled tight.

When you install the chain tensioner, this will cause the chain to roll slightly. So if you can not line up the marks perfectly, favor the non-tensioner side.

After you have installed the tensioner, rotate the engine one revolution, align the T on the crank, check the cam bolts or marks to be even with the head surface.
