How many top 250 riders have had mechanical problems? Chad Reed on his Junky Yamadogs. First the powervalve on his YZ 250, then the infamous "we're not ready to release the information yet" electrical fiasco and now they can't even keep a chain on that rag. How many mechanics does it take to keep a Factory Yamaha running? To numerous to mention. Anyone brave or dumb enough to buy an 06 when the factory mechanics can't even get their bikes to run?
