When riding this afternoon, I noticed increased noise (sounds like piston or cams?) coming from what appears to be the top of the cylinder head around the camshaft on the right side of the engine only - left side is quiet. It sounds like metal rubbing at approx. the same RPM as the engine-maybe slightly less. Noise gets slightly louder at higher RPM's. Bike is 01 426 w/ about about 3 hours max on it w/ BK mode and runs freakin' unbelievable!! Anyone else seen this symptom? Also, anyone know a GOOD Yamaha mechanic in the Dallas-Ft. Worth area? I've pretty much lost confidence in reliable service w/ the shops I've visited. Thanks to all fellow Thumpers!!
