My 2015 Suzuki Gixxer (34000+) is making strange noise like (huu-waiiiiiiiiii).It seems to be whirring under deceleration when clutch is released but as soon as i pulled clutch the noise is gone its really quite. The whirring noise grow the longer i ride. Maybe the engine get hot or something. Also there no noise in neutral or when idle. that is the exact reason i cant pinpoint problem cause i dont know where the noise is comming from while riding. Also its is lightly ticking like tik tik and knocking sound like kat kat. But strangely i sometime hear it sometimes i don't. But i definitely don't hear any thing on idle or neutral.
