My son's 2012 has never ran all that great and after a disappointing trip to st Anthony dunes I decided it is beyond my skill to figure this thing out. Problem is I am in western Montana where the dealers have never seen a yfz let alone tune one with a slip on and various elevations. Anybody know a shop that could handle this within a couple hours of Missoula or a owner that I could pay that knows the mikuni? Or should i buy a kehin? Appreciate any suggestions.
