SOURCE: correct timing chain marks. is a diagram available?

if the timing chain is off i dont think it would run, id suggest getting you're cams checked and reseat your valves, i have the same bike and an electronic copy of a repair manual, not for the exact same bike however. i have not been able to find the correct copy.

hi karen, that is right, i do have a DT 125 myself and same thing has to be done.

Usually this is balance the engine so that the moving parts will move to a limited place. this is also to avoid further block damage when the piston is moving up and down.

Put the piston at TDC (Top Dead Center) by lining up the timing marks on the flywheel and stator. Put the cylinder head back together with the cam installed so the high points of the cam lobes are pointing kind of downward. Pull the cam chain taught on the front side of the engine. Put the chain on the cam gear such that, when bolted to the cam, the index mark or marks are in the proper position.

The proper position depends on what markings are on the cam. Some bikes have a single mark; an arrow, a straight line or an "O". The mark should line up with the center-line of the crankshaft. If the cam has two marks opposite each other, the lines should be parallel with the gasket surface. You will need to rotate the unbolted cam left or right just a bit in order to match up the bolt holes to the gear holes.

Can I get a “very helpful” rating on this answer?
