All sage advice, here. Trust me, many on this forum know everything.... and I mean EVERYTHING about the FJR1300. They can take it completely apart, down to the last bolt, and fix anything that could possibly go wrong.
But those guys and most of us will tell ya that, you may never (ever) have to worry about that. In fact, I dare say that your biggest concern for your FJR1300 is NOT riding it enough. They are as bullet proof as they come in the sport touring segment. There is a reason why the FJR is always listed in the top 10 of the Iron Butt Association rally. You ain't gonna ride 1000 miles a day for 15 days straight unless your **** is running and ready for abuse. Truth, man.
On the other hand, don't turn a blind eye. Flush your brakes and clutch thoroughly and lubricate all of the pivot points, and the drive shaft splines. At the next oil change, check your valves, flush your coolant, put in new spark plugs, and if you have a manometer, check the sync on your Throttle bodies. Wouldn't hurt to flush the fork oil out, but don't over-sweat it.
Then ride it, man. Ride it often and for as long as your arse can stand. Ride it as hard as you like, or if you prefer, throw her in 5th gear and just cruise. But ride it.
And bring your camera with ya when you do. Share your (s)miles with us....
