I have inherited a 2001 YZ426F that has seen it's better days and am looking to get it in running order. I have bought new F/R sprockets, new chain, new levers and new grips. I plan on pulling the carb and giving it a good cleaning as well as fresh oil/filter and radiator fluid. I also need a new fuel petcock as the brass bung the fuel line attaches to on my bike has slipped loose out of the petcock itself. Can anyone point me to a good replacement. Any petcock "mods" to do while I'm replacing it? Thanks in advance and yes, I already downloaded the manual!!
