great shop, nice guys.
I bought a YFZ from Rich, one of the owners and it is absolutely the fastest "stock" yfz around. I have smoked more yfz's and modded raptors with it that I ever expected. Great bike Rich!
Also I rode one of RPA's big bore YFZ's at Sand Mtn in 08 and fell in love. It rode so smooth with the extended swing arm and had ample pull up comp hill. It was a very impressive ride.
If you have a YFZ in Northern Nevada get it to these guys and let them do their magic!
