I know this is a crucial part to get proper timing, what is the best way to do it??

 

put the chain around the cam sprocket (but dont install the sprocket, just keep it in the air) then get the chain around the crank sprocket, then install the cam sprocket make sense? worked fine for me last week. hth

 

And don't forget to line up the dots on the gears.

 

cool. thanks guys.
