So I got a 2004 s model, bought it not running blah blah. Cleaned carb got it running. Got a chance to check valves today. One intake was out of spec. One is is spec but on the low end. And same for the exhuast. The computer says 1200. Yes one thousand 200 miles. But the speedo cable is broke. Is it normal for them to all start getting tight at once? And I don't know how long I'm keeping it. Questions are as followed 1) Is it worth buying the shim kit? Or buy the individual shims needed. 2) should slap new valves in it? 3) how often do they need to be shimmed? Any and all help is much appreciated.
