Valve Clearance - Help Needed
640 Adv 2004 Having a bitch of a time adjusting the valve clearance - well I can adjust the valves but how the F!§#~#} does one get the piston to stay at the top - ie the little mark or line on the window that indicates the top position. Must it be at the 12 o clock position? I presume it does, can only get mine to stay at the 2 o clock position which after adjusting the valves I realised is wrong.
Is there a trick to it?
Any info please
