I unloaded 01 YZ125 and rode it for about 15 minutes yesterday. When I put it on the stand I smelled gas really bad and looked and found that there was a 4 inch crack in my gas tank and there was gas leaking out everywhere. What could have caused this? I didn't drop the bike at all when I took it for a spin and it wasn't leaking when I filled it up.....Does anybody know where I can get a new gas tank for a 01 YZ125?
