Message: [QUOTE="DualSportr, post: 141722, member: 19592"] The "feel" for adjusting valves is a learned thing. To properly do it the first time, it would be really good if you had a friend who has done this and knows the feel for the right amount of drag on the feeler gauge. This way, he can adjust it, then let you see what the correct drag, too little drag, and too much drag feel like. If this isn't possible, then the best way to describe it is you want to be able to feel the "pinch" of the tappet nut and the valve without feeling like you're marking the metal of the feeler gauge. If you're not sure, try to insert the next size larger - if it fits, it's too loose. Try the next size down, if you feel drag with it, then it's too tight. Angled feeler gauges will make your life much easier with an RFVC. If you don't have them, you'll have to get them or bend the ones you do have. Honda makes trick ones which are really easy to use (not as wide, nice handle), but they're spendy. Also, if you have compressed air, blow off the area around the valve covers - dirt gets caught in the little depressions at the top of the head and has a nasty habit of falling in the engine while you're adjusting valves. If you're really having a hard time getting the right "feel" - remember more clearance is better! Over-tightened valves are worse for an engine than loose ones. [/QUOTE]
