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.

Which valves should b open at tdc on an 87 cavalier?


for tdc on compression stroke --none
for tdc on induction stroke both one will be closing (exhaust) and one opening ( inlet)
the condition is known as valve rock and when the cam is timed properly --a bit before to a bit after you will see the valves move accordingly- that is when the timing marks will line up or a turn of 180 degrees will line the marks up
only need to work on no 1 piston as the rest are in set positions by the cam design

I believe the timing marks no longer line up after replacing my timing belt. How can I determine if correction is needed? How do I correct timing mark alignment?


there is a method but you will have to have an understanding of valve timing
in an engine regardless of number of pistons when number 1 piston is TDC not firing, then the exhaust valve will be open and ready to close and the inlet valve will be closed and ready to open
so bring the piston up and near tdc
as you approach tdc you will see the exhaust start to close and at the same time the inlet valve will start to open
if you rock the crank back and forward slightly at tdc you will see that the valves are rocking
this is valve rock and indicates the cam is in time with the crank
it is only necessary to do it with no 1 piston
It doesn't matter how many cam shafts ( one cam shaft can be inlet valves only and the other can be exhaust valves only) there are, it is the exhaust and inlet valves for no 1 piston that you are looking at
how do you get tdc-- remove a plug and with a piece of wire place the end on the piston crown and as the piston comes up the wire will be pushed out as you rock the piston the wire will move in and out and the point before movement is tdc
probably as clear as mud unless you are engine savvy

How to time 2008 crf150f honda


Hey Lisa,
What are you needing to "time" ... the camshaft?, ignition?. IF you have taken this engine apart??.. the ignition will take care of itself when the engine is reassembled.. but you need to read one of these..
. The piston must be at TDC on the compression stroke and held there while you time the camshaft..there are marks on the cam sproket ,,(the lobes on the cam must be opposite the rocker arms.),, I am not sure exactly what the cam timing marks look like on this particular engine.

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.

Where can i find the timing mark for a 1996 bmw 316


Hi, to set the timing you should turn the No.1 piston to TDC, then turn the cam to where both valves on No.1 are close. The timing mark on the sproket should now be in line with the mark on the cilinder head. With No. 1 still on TDC fit the chain.
After fitting turn the engin a few times by hand to make sure there's not a valve pushing against a piston.

Honda gxv140 cam timing.


Hi
There are two marks on the bottem of the cam gear that need to be flush with the top edge of the head (mating surffice of valve cover). And the key way on the crank needs to be turned up inline with the cam shaft.
