Exhaust port cleaning
Am in the process of doing a cam replacement, and when I removed the exhaust pipes, the ports are really disgusting, especially the rear one. How do you clean out the old ones and how clean does it need to be? Pictures would be nice. Thanks

how many miles on the motor? if its really really bad, you may have some valve guide/seal issues, but I'm thinking its not all that bad. don't worry about it. As long as you can seal the pipes up to the head, You'll be fine. if in fact, the valves have a lot of carbon on them, you might think to remove the heads and inspect the guids and seals. what year bike?

Not this time
Not gonna happen since the cams are sitting on my bench. Do you need to position the piston below or above the opening? Do you steel wool or a brass brush or electric drill and wire brush? I how do you clean it out?
