I keep having problems with tdc and the arrow marks being both level. the cam chain tensioner moves tdc line. So I read up on some forums and found that you can count 45 marks and line them up, but i seem to be having trouble with it still.

If the cam chain is moving the crankshaft, then . . . perhaps you are on the WRONG TDC!

TWO piston TDC positions occur with each four-stroke engine cycle; between compression and power strokes (that's the one you want), and between exhaust and intake strokes.

At TDC between compression and power strokes (the one you want), the cam is under no directional pressure from the valve springs . . . ALL valves are COMPLETELY closed. At the other TDC, valve spring pressure impinges upon the camshaft lobes, imparting some rotational force on the crankshaft.

Kinda hard to explain, but . . . at the correct TDC, the camshaft surface presented to the valves is radial; at the other one, some camshaft lobe slope exists. Actual valve CLEARANCE exists between the camshaft lobe surface and the valve-lifting mechanism at the "right" TDC.

So . . . check your TDC point out, make sure you have the one you want. With all valves completely closed, you're getting warm!

bubbazaay,
I'm sorry that Kawasaki didn't put the arrows on the Sprockets, "QUITE Correctly".

When the Crankshaft is at TDC and the cam lobes are 'kind of pointing' at the Gasket Surfaces of both front and back of the cylinder head, the ARROWS WILL Point about 5 degrees above gasket level.

This is NORMAL and Correct.
Carefully put it together and carefully Torque all the bolts to Proper Specs.

Enjoy the ride. :)
