strange sound from the front and pulsing from the exhaust
I searched alot about the issue before I posted here, but couldn't find anything..
simply, I have a new 100% stock 08 bike, started from 0 miles and now arrownd 250 miles I'm geting more familiar with the bike and feel much more from it..
what sounds strange to me is that low pitch whistling sound, or more like a sharp horn sound from the front, not strong, I can barely hear it, is comes at arround 5200RMP and goes away after that in about any gear, but can't hear it in 5th and 6th due to wind noise, so it is not so bad, but I still can hear somethig.
is it normal sound coming from the air sucktion throught the ram air?
and the other thing, when let's say in 2nd gear, I ride slow in a small road and keep the speed constant at 3000-3200RPM the exuast makes sort of pulsing sound, idles perfectly and any RMP above is OK, only pulsing sound, no jerking and no abonormalities in engine output,
is it just resonance at that RPM? anybody with stock bike has the same issues?
