AP1 S2000 Engine ticking - Stumped!!
Valve adjustment tip #1. The adjustment process of the valves is identical to many older Honda motorcycles. Almost no cars have adjustable valves anymore, so most auto mechanics have never done one. Hence they shy away. You don't want these guys doing it anyway. Find a good local bike shop that works on Sportbikes. Other than bending over a hood, its a job they've already done hundreds of times.
#2. If diy, there really is only one way to screw this job up royally. That is the complicated prpcess of aligning timing marks and counting rotations, etc. Fortunately there is an easy, foolproof solution. Ignore the timing marks.
Simply turn the motor until the valves you want to adjust have their cam pointing up, 180 degrees away from the follower, pointed away from the valves. Thats it. Simple. This is a technique I learned doing the same valve adjustment on bikes back in the day. It works, and eliminates the problem most run into that makes them do over.

Appreciate all the great advice from everyone, I have had an unbelievably busy weekend and wasn't able to get to the car until today. I adjusted cylinders #1 and #3 and found that all of the valves were extremely tight. On the exhaust side my .010 feeler guage was nearly impossible to get into cylinder one exhaust, and was nearly as difficult with the .009 on the intake side. Cylinder #3 fared slightly better but all valves so far have most definitely needed adjusting. I am going to have the valves finished and get the engine all tidied up tomorrow. Hoping for the best, could extra tight valves cause noises to these levels or is that just wishful thinking? Something was definitely wrong with these valves
I also made another interesting discovery, when I replaced the serpentine belt I had actually put it on wrong. I fixed that and noticed *slightly* less noises, but the belt was definitely never a significant problem. Car will be running again tomorrow, either purring smoothly or just as rowdy as before. Again I am not sure that extremely tight valves could cause this? This is uncharted territory for me..
Adjusted the valves, changed the oil, car makes a much different noise now but the noise lives on nonetheless. I can't find anything wrong with anything under the valve cover, so at this point I'm assuming it's going to need either a partial or a full rebuild. Again..
