Since it's a low miles new to you bike, here are a couple of things.
Learn and read up on hydro lock, something to know about, not to worry.
When you do your plugs, check the drain holes at the bottom through the heads, make sure they're clear. A piece of copper wire, up from the bottom, easier to find the holes.
The mention of the red dust, yes, that and all to do with the rear drive. Something that can leave you stranded and out some real coin $. Shoptalk above, rear end service by ChrisJ, is a must read.
Service manual, PDF, I also like a paper copy, used come up from time-to-time.

I spent 8 months reading old posts in this Tech section, trying to learn about our bike, before I picked mine up. Trying to learn things I should know, problems and fixes for what might come.
At 48K miles, a 1/2 can of Berryman B-12 for your next 2 fresh tanks of fuel, should insure that the carbs are clean. Check your petcock operation the next time you're on the hwy, turn it off and wait for some sputtering, then back on. Just to insure it's working as it should, I do this once a week.
Not likely to find a knowledgeable mechanic/shop, so learn from the people here, ask questions first, like you've done. I like how you are asking already, what's the easy things to do first, before just going for the shop seal repairs.
