I think it's a tough call. $100/year is pretty cheap as extended warranties go. OTOH, the FJR seems pretty bulletproof - the only thing that appears to be an issue at all is the ticking and Yamaha is fixing these without YES.
And like you, I'm also doing all my own maintenance. For early problems, I doubt Yamaha is going to make this much of an issue, but if I wear out a camshaft or lunch a main bearing at 60K miles and 3.5 years, I wonder how waving a bunch of dog-earred receipts for oil and oil filters is going to fly insofar as showing the bike has been properly maintained. In many ways, life just gets simpler by not getting it and fixing the odd problem that might occur by oneself.
I've got six months or so to decide.
