Open the end cover and turn the crank with a wrench. Examine the piston and cylinder for pitting before a rebuild. If OK, clean out and polish with some of that 3M scrubby stuff. Just smooth enough to a finger nail is good.

To: "Nighthawk Motorcycle Lovers!" <[email protected]> Date: Saturday, October 24, 2009, 8:44 AM Thanks for the help. I have a battery coming in next week. I'll try to turn it over then.
