I has a problem. Finally manned up and checked my valve clearences. I did just as the manual said: * remove cam cover * set to TDC (line up with the I mark) * measure clearences. Thing is, when I get it to TDC I can't get my feeler guages in either intake or exhaust cams. I have rotated it to all different positions. When I finally get a guage in the inlet side reads .19mm. when I finally get on in the inlet is about .8mm. What am I doing wrong? the bike starts perfect. first kick. Also, could loose valves be the cause of a top end rattle. It isn't at idle only sounds when its mid to high rev range (in netural).cheers guys!
