Download a manual if you dont already have one, make sure that little dot on the crank is lined up withe the arrow on the sidecover, then look at camshaft lobe ,the lobes should be facing rearward.and the reference (DOTS) ON THE CAMSHAFT SPROCKET should be lined up with the surface of the head, hopefully you didnt do any damage kickin it over. Always doublecheck your work before buttoning up.
