Hello all! I'm new to the community (and a new bike owner) and I'm concerned about a noise coming from the front end of my 2001 CBR600 F4i. It's a grinding/whirring/rattling (very hard to describe) coming from a spot that seems to be just below and in front of the gas tank. It starts after the bike has warmed up, OR if i half-shift instead of shifting cleanly into 3rd. Once the engine starts making this noise it makes it in almost any gear over 3,500 RPM (engine noise drowns it out around 7,500 RPM).. If i stay in 1st/2nd i don't notice the noise until my engine is around 200-220 degrees. Any insights??
