Are there any tools (angled Feeler Gauges or Straight for example) that make the job easier? What tips can you guys provide for doing the first inspection on the bikes I just bought? Neither bike have an hour meter on them. Bike #1 has no more then 10 actual hours on it after looking everything over. Bike #2 has seen more but no way to tell. Can you sort of gauge the hours by they amount of lash in an untouched engine? Generally speaking, how thick are the valve shims on a stock engine (I am sure it varies just just trying to get an ideal)? Joe PS. I have the manuals but am just looking for added tips.
