Welcome to one of the best bike specific forums online. Bike looks good, though I have to admit I don't care for the plastic chrome car door edge guard around the fenders and tank. I noticed someone removed the emblems, I removed the sidecover emblems on my '02, well actually they removed themselves. They were coming loose, and my pant leg caught on the right one and ripped it right off. I may also remove the tank emblems and replace them with something else.
As was mentioned, the spline lube is the absolute first thing you should do, before even riding the bike. Virtually every Vulcan 750 ever made either didn't have the splines lubed, or they did it wrong. Hopefully you will catch it in time. It is NOT a cheap fix.
After that, just get a service manual (I like Clymer), and start doing all the services, except the steering head and swing arm bearings. That is such a major job I would leave it alone unless you notice a problem. They can wear considerably before becoming dangerous, you will have plenty of warning. I would not disassemble the swingarm or steering head unless I was going to replace the bearings. other than that, oil and filter change, coolant change, final drive gear oil change, replace fluid in front brakes, check pad and shoe wear, replace if necessary, replace or clean and reoil air filters (I just replace mine, I get the Emgo filters from denniskirk.com for a small fraction of the cost of Kawasaki oem originals), remove, disassemble and clean the carburetors, then maintain with Seafoam, lube and adjust the cables, replace the stock battery with a maintenance free AGM battery if it doesn't already have one, some claim iridium plugs help starting.
If it were mine, I would remove the CA evap emissions system (if it is a CA model) and the air injection system, they are both nothing but trouble. Bike runs much better without all that crap. Read about the cam chain tensioners (I recommend the manual ones if you have problems), the stator, and the balancer. Then go RIDE. Jerry.
BTW, 20,000 miles is nothing for a properly maintained Vulcan 750. I put over 80,000 on a '93, and currently have over 44,000 on my '02.
I am a motorcyclist, NOT a biker.
