I have a GSR with 17,000 miles and all I've been doing with regards to maintaince is oil changes and other fluid inspections. I was just curious do you think it is really necessary to get a valve adjustment for the first 15,000 mi? I heard it's kinda expensive and on a relatively new car do you think it really needs it? And what are the possible complications down the road if I waited until 30K mi to get it done?
