I start to think its a rip off and maybe he did something bad to my bike. No doubt it seemed smoother, but i used to be able to reach 110km/h v smoothly. now it seemed v vibrate-y. but up to 100km/h seemed smooth. he told me he did me a favour in changing the clutch plates too. but then when i kick gear, v hard to reach neutral. i went to planet he say is the clutch plate problem. so i think he is quite bullshit. oh wells expensive lesson learnt!
