Just put on my tb v2 race head on my yx160. Found tdc and set timming. Did vale clearances. All is good but when turning over by hand I hear clicking noise in the head as it turn over tdc. It clicks just as the valves fully open. I installed piston with IN that is stamped on piston up. So don't know if valve hitting piston. Looked down spark plug hole with camera but i don't see anything. Any help guys
