At the end of my ride on Sunday I noticed that my bike started making a whiring type of sound. I'm not sure if anyone else has experienced this noise. Whiring is the best that I can explain it and it seemed to get higher pitched with higher rpms. I was thinking that it was possibly the water pump, but am not sure. The bike is only five months old and has the following mods: air box, reeds, FMF pipe and silencer, stock jetting. My first enduro is in 2 weeks and this noise concerns me. Where should I start? One last thing, the conditions were very dusty and I have yet to clean the filter could lack of air flow cause the sound?
