Sorry if this has already been answered but searching is turned off right now. Does anyone know if the WR's are eligible for the same valve fix as the YZ250F's? They have the same engine so I imagine that the same issue could occur. I tried calling Yamaha a couple of weeks ago but the customer service person I spoke with didn't know the answer. She offered to have one of their technical support people call me back but I never got that call. I'm just wondering if anyone has had any luck getting that information. Thanks!
