Sounds good, I'll get it cleaned up then. The previous owner was one of those guys that would just wheelie it down the streets, so I'm sure he didn't think twice about the fuel he was putting in it. Thanks for the help!
Hey guys, I just picked up a running 03 yz125 a few weeks ago and upon tearing down the top end, I noticed the cylinder head looks a little beat up. Is it possible to just clean it up or am I better off just buying a new one? Thanks guys.
