Q. I have a 2004 Yamaha FJR1300 with nearly 90,000 miles. It's been well maintained (grease, oil, coolant, plugs, pads, and tires) and ridden sanely as a daily commuter and summer sport-tourer. In my neck of southwest Georgia there were only two Yamaha motorcycle dealers, both many miles away from my home. When the FJR was ready for its 30,000-mile valve check, one of them discouraged me from having the factory-mandated service, saying it probably didn't need it. By 60,000 miles the other Yamaha shop had changed hands and brands, so I tried a local independent "motocross" shop and was told it would take a week and cost more than $600. I passed.
