Started the bike up today and i'm hearing some type of squeaking noise from the front of the bike, possibly in the engine. I can't nail it down. It happens in the first little turn of the throttle, but only squeaks briefly. Then when I let the throtle off and then twist it again, it squeaks again. Also does it during downshifting when I let out the clutch and when I turn the engine off. I just installed a GPI w/ATRE this weekend and a K&N Filter. Did I screw something up???
