when I engage my bike into first...after starting it up it engages loudly...and when I shift thru gears theyre heard too.Ive owned many kawi.s and this was always a characterist thing but I figured this would not be an Issue with this year???would an oil change help that?? I read a thread on a zx9 that said this resolved his issue.which brings the next question...what oil should I run???synth.or what???Ive read the pros and cons on threads about that too...mobile1 synth.isnt really a synth.oil???...the guy I bought the bike from said dont run a synth. Its hard on clutch plates.guy at work rides v-twins said that he runs lucas oils???the bikes got 14k on it. any advice????
