those bore scopes are great for checking to see how well your carbs, intake manifolds and head port all match up. take off the air filters and thread the scope in. The one I have will fit into a 10mm hole so it goes right down the spark plug holes as well. You can check out whether you valves and pistons are being burnt or carboned up, or what ever.
very cool technology.
