Line the second mark on the flywheel up in the hole on the left cover that is top dead center, that tensioner i believe you have to prewind to bring it back take the bolt out and use a small screw driver and wind it back in and leave it in there untill you put the cam back in and bolt it down. make sure you use caution when removing the bollt from the tensioner it is spring loaded. the cam sprocket has lines or dots they will need to line those up with the gasket surface make sure there is no press on the valves that will be top dead center comp

Trying to find out the timing specs of the valve timing


Hello,

If you are looking for the Valve clearance on your bike, both Exhaust and Intake are set at 0.004" at TDC on the compression stroke.

Regards,

2003 crf 4 stroke. has compression. no leaks. engine sparking. fuel system fine, plug wet. engine wont start?


Gotta start with the simple things...
How do you know the compression is fine? Since you did not give a compression reading I do not know what method you used to test the compression.
How do you know the fuel system is fine? The plug is wet with what? Could it be water?
How do you know the spark is fine? Have you used a spark tester? Or did yuo use the spark plug on the side of the head? Did you know a bad spark plug can still spark under regular condition but wont spark under compression?

You left out valve timing- its a 4-stroke.
First put in a new plug. Then see if it hits on a prime ( see my tip on diagnosing a small engine).
If you have double checked all the basics and are sure we have fuel,compression, and ignition and it still wont start then check your flywheel key and valve timing.

How do i fix the timing on a 2005 honda crf450x


I am guessing you are talking about valve timing, since the ignition timing is not adjustable?

Rebuilt top end and now wont start just backfires but all timing


if you went by the manuals timing mark instructions you should be fine but i'd bet its still not in time. the lines on the cam should line up parrallel with the head casting, most times it looks like they are but its still one tooth off, i usuall put tensions the chain with my finger to see how parralell they are.. make sure the motor is in top dead center compression also. the manual is what shows your at tdcc.

04 crf 250r.... the head has a chattering noise when running


Any chance the valve spring has collapsed? Cam shaft thrust washers missing? Cam shaft bearing gone bad?
