Hey Jim,
I have a 2005 WR450f and on the right side of the cylinder their appears to be a hole that looks like it should have a bolt or some kind of a plug in it. I have looked on line and in various repair manuals and cant find what the %$#!! is suppose to go here. Any thoughts?
The bike runs fine but has me stumped as far as this what appears to be a factory pre-drilled hole
