98 zx6r valve adjustment price
I am not a tech so I thought I should ask here. I took the bike to champion cycle and talked to the guy about weird valve noise and a leak near valve gasket. He recommended to adjust valves since it sounded like it needed it..Also, he said he has to do oil change with that. all is going to cost $400. is this a fair price and do you need to change oil when you are adjusting the clearance. bike is 98 zx6r and got 59k on it ..it sux cuz i just did oil change about 700km ago.
