As I was going to adjust my tappet clearances, I found that the left hand intake tappet screw is missing. I know it was in there originally when I got the bike because this is my second go around with adjusting them. I have yet to perform a compression test, and figured if I'm going to remove the valve cover (hopefully finding the tappet screw tucked away), I might as well go further down the rabbit hole and check pistons, valves, etc. if the compression is low.
My questions are 1) Can I safely perform a compression test knowing there may be a tappet screw floating around somewhere in the crankcase (hopefully bottom, if not luckily still in valve cover) and 2) would a strong magnet on the outside bottom of the crankcase be effective in catching the screw and dragging it towards the drain plug (assuming it has fallen to the bottom)? I recently pulled the right cover to do an oil change/filter clean, did not notice it sitting at the bottom, so I think I can rule that out - may pull it again just to make sure, wasn't exactly looking for a piece of machinery at the time.
