Well I pulled, accidently broke off some fo the light blue wire. Installed my frame gaurds, changed the oil filter, and drained the oil. But I cannot get the oil strainer to break loose. The biggest size metric wrench I have is a 22(what siz is it?). Every fastener I've loosened so far is rediculasly tight. What size does it take, and has anyone else had this problem. I don't want to strip it anymore then it already is.
