My bike is a 1998 wr400fk. I have owned it since day one. It has a right side case with an additional part of the casting that could be for an electric start. It is in right place for a starter. this part of the casting has a machined surface (ready for a gasket) but does not have the mounting holes drilled or tapped. is this part on my bike also used somewhere else in the yamaha line or is this a prototype??? My bike was the first one the dealer got. Does anyone else have this same case? I have never seen another one, neither has any dealer I have shown it to.
