Turn the motor over clockwise until the punch mark on the gear lines up with the arrow mark on the side case. Check to be sure that the cam lobes are facing to the rear of the bike, if they are pointing toward the front keep going until they face back and the punch mark aligns up with the mark on the case.Honda CRF 100 timing - ab798e0.jpg

Check the cam gear to make sure the two marks on the gear are level with the surface of the head.

Cam timing


you have to make sure your piston is at TDC starting to go down into theintake stroke, and set it so the intake cam lobe is opening the intake valve as your piston reaches TDC.

How do i set the timing on a yz450


Set the piston to TDC (top dead center) this is the higest point the piston will rise before moving on to the down stroke, either by lining up the marks on the crank rotor or a long screw driver (large handle so it wont fall in) down the plug hole and watch for the highest point lock or hold at this point. If cam sprocket has marks line them with the cylinder head surface (sometimes the sprocket bolts) parallel.
The cams should be fitted next on the 'compression' stroke meaing the all valves should be closed when the cams are seated (no valves being pressed by cams) generally at this point the cam lobs face away from the valves , next stroke down (ignition of fuel) valves should be closed with the exhaust cam moving round ready to rock on to the exhaust valve as the piston rises to the top again (4th stroke exhaust) as the exhaust valve lobe rocks off the intake cam lobe should be starting to rock on opening the intake valve on the down stroke of the pistion.
Trun the engine over by hand to make sure no valves are knocking the piston.
Should be as follows
1. all valve clearance free/rocking at ' TDC 1st 'down' stroke (ignition of fuel) valves closed exhaust moving round but not pressing valve ,
2. 2nd stroke 'up' exhaust valve rocking open and closing as piston tops with the intake ready to rock on as the exhaust closes and piston tops (exhaust),
3.3rd stroke 'down' (intake of fuel) as the piston moves down the intake valve should be opening.
4. 4th stroke 'up' compression of fuel all valves rocking closed as the piston rises for the compression stroke back to TDC all valves closed/rocking free.

Intake, compression , ignition and exhaust. (**** squeeze bang blow)

I have a 300 honda fourtrax how do u put it in time


ther are some plastic plugs on the left side case cover, the timing is set with the piston at TDC, Top Dead Center, the piston is at the top of the compression stroke and the cam lobes point up, this is also a good time to check valve clerance. to set timing rotate the motor slowlly untill a notch is visible in the window of the small offcenter side plug or maybe marked T but not F. the cam gear also has a mark that corisponds to a notch,

How do you remove timing chain and re-time eng


If you need to remove the cylinder head, here's how. To remove the cam chain, you've got to also remove the left crankcase cover and flywheel.

First, you need to turn the engine over until the piston is at top dead center (TDC) of the compression stroke. Begin by removing the two round covers from the left side of the crankcase cover. Also remove the four tappet hole covers from the cylinder head cover. Turn the engine (in the normal direction of rotation) and watch the intake valves open - and close, then see that the exhaust valves open, then close. Now align the 'T' on the flywheel with the notch in the inspection hole. With all of the valves closed, the engine is at TDC of the compression stroke. Do not begin removal of the cylinder head cover until this is done - to avoid damage to the cover.

With the cylinder head cover removed, you will find two bolts attaching the cam chain sprocket to the camshaft. Turn the engine until you can get a 10mm socet onto the heads of the bolts and remove them. The sprocket will come loose and slide down onto the camshaft, enabling you to remove it an the camshaft.

Upon reassembly, set the cam timing by first setting the engine at TDC. Then, align the two marks on the cam sprocket with the gasket surface on the cylinder head. With the engine at TDC and the marks lined up, the cam timing is properly set.

Before calling the job done, make sure to adjust the tappet clearances to .002" on the intake and .003" on the exhaust valves.
