I noticed after bringing my bike out from hibernation, when I'm cruising around a strange humming noise is coming from my front end. Not sure what this is, that's why I'm posting this. Maybe you guys can help me out. I usually just keep the rpms high so I don't hear it haha. Should I have the dealer look at it? It's under warranty for another 2 years.
Humming noise?

yeah i hear the same thing. it might be the the clutch lever. it kina sounds like the the plastic on my key chain is vibrating, but thats not it. a lot of other people with 250's have this same problem. i don't think its anything serious, but i would like to know what it is forsrue
If it was a bearing noise it would change pitch or "hum/vibration" with different speeds. I have yet to hear this noise, but alas my bike only has 75 miles on it. I tend to have good hearing also.
When do you hear it? At low speeds, higher speeds, same RPM range? Does it go away when you turn? Sometimes you can take pressure off a bearing that way but............
So many rotating parts in there. Try to notice while your driving when its happening and let us know

my seems to happen around 8-9k rpm. i here it the most in the lower gears 1-3. its not very loud either its like a faint hum. definitely not like a rattle or anything. like i said earlier its like some plastic part that is vibrating really fast, which could be a lot of things since our engines love the high rpm/vibration and we have a lot of plastic parts. it does go away when i turn, but i think its more due to me slowing the bike down and dropping rpms. now that i have my two bros exhaust on i probably won't even be able to hear it.

My guess is the air box cover or battery cover fairings . The plastic pin(s) may have popped out of the rubber grommet. They seem to come out easily. Air may be passing around this and causing shuttering , humming, rattling or whistleing.

It sounds like it's coming from below the gauge area, I've always heard this on my bike. I found a thread on kawiforums and it seems some of our bikes do it worse than others. mine is real bad like 8-9K. But it is nothing mechanical.

I couldn't find it on the sidewall, hard to see. But thanks man, my pressure was on the low side. I'm gonna take a ride tomorro (too cold 2day) and mayb the humming will be reduced or gone. The front had 20psi in. and the rear 25.

ouch they are a bit low arnt theyy.
Yea and the valve caps were on so tight. I thought the dealership used lock tight or something. I noticed that a clip on my fairing was pushed out leaving a gap of about 1/8" that may have been causing the humming noise. We'll see tomorrow when I take it for a ride.
