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

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?
