Welcome. I'm also in AZ. First thing you need to do is get a manual. If you have had other motorcycles, the Vulcan 750 is completely different from anything else you may have had. It's a real oddball. One of the things I like about it. I have already gone with the manual tensioners, after a 2 year battle with the automatic ones. Some other reasons for a ticking noise are the lifters not pumping up correctly because they are dirty, or not holding pressure due to wear, a vacuum leak, or the air injection system valve. I have removed the complete air injection system from my bike, as well as the CA evap emissions system, and recommend that everyone do it. There is plenty of information here on how to do it. The Vulcan 750 has a mechanically complex engine, with a lot more moving parts than most motorcycle engines, and some mechanical noise is normal, though I have had much simpler inline fours that made more, because they were air cooled. The liquid cooling dampens some of the noise.
It is my opinion, as a professional auto mechanic, that the Vulcan 750's cooling system is pretty marginal for the AZ summer heat, if you live anywhere near the Phoenix valley. It simply doesn't cope well with stop and go riding when it is 115+ degrees. Mine runs hot in the summer too, but is doing fine right now.
By the way, I prefer the Clymer manual. You should be able to find it at the library. The Vulcan 750 has not changed since it became a 750 in '86, till production ended in '06, so the manual covers all years. Jerry.
