Excellent advice here Classic! Getting to know all aspects and idiosyncrasies of your bike is probably one of the most important things you can do for yourself. Knowing how and what to talk to Service people about, troubleshooting on your own, roadside diagnostics and repair, etc. Anything you can do to insure your bike is always running well, is serviced properly and there's less chance of getting ripped off too. Breaking down on the side of the road sucks. But there's nothing more gratifying than to determine the cause and fix it, right there on the side of the road. You'll also be able to participate actively in any discussions regarding modifications you'll want to do. All this helps you get more intimately involved in the maintenance, repair, and modification of your bike. And it makes all these processes so much more fun. After all, if you're into something, it's fun then!
Great advice on Manuals too. Get them all. They're invaluable. And get familiar with them. Read thru the exploded views of the parts manual. It gives the best layout and understanding of all the components that make up your bike. Forums like this, especially this one, are also invaluable. You're here, so you already know that! And yes, all the sensors on the bike run around $300. And there's a good chance when one goes, they won't have it in stock. Or it goes in the middle of nowhere. I carry all these sensors with me all the time. Maybe I'll never need them, but if I do, I'm not hung up waiting to get it. Could save you a couple of overnight stays on the road sometime. And I carry a spare, preprogrammed PC III in case it fails as well, since the bike can't run on a stock ECM program.
Some very wise recommendations made by FXR2 here. And I'd recommend this to everyone, new and seasoned riders alike. Involvement and planning can save your butt with these bikes. GET TO KNOW YOUR BIKE. You'll never regret it and makes the whole experience so much more fun!

Hoist!
