So i have been having a problem with my gas cap. The key was getting very hard to turn. So i disasembled the lock and loubed it with graphite. The locked worked amazing, for about a month. Tonight I broke the key off trying to open the tank. i got a spare and limped it home, but i am out of gas. My question is, am I lubing it with the proper stuff????? My bike sits outside, covered most of the time. I was afriad to use andthing that might drip into the gas tank. Anybody had this problem?????? Any insight???? anything would help as I plan to try to solve this ASAP. Thanks!
