I got 40K+ out of the first chain on my 2011FA. I'd suggest replacing the sprockets every time you replace the chain, unless you're doing a lot of dirt riding and are going through chains at an abnormally high rate. I've had plenty of sprockets with considerable visible wear (comparing them with the new ones) without looking "shark toothed. "I'm using chain and sprockets purchased from Dale Walker at Holeshot Performance. Bikemaster 530 gold chain 530 - 120 tooth. 18 tooth and 43 tooth sprockets are stock sizes. Use heavy steel sprockets - the aluminum ones wear out too fast.
You'll need to remove a couple of links from the chain to get to the 118 tooth required - leaving 120 on will put the adjustment points too far back. You can probably get a continuous chain at 118 links from Suzuki OEM parts houses but it is a lot more expensive and cutting/installing chains is pretty easy. I think riveting the ends with the supplied master links are the best way to go - i don't trust the clips or screwed on ones except maybe in an emergency. ALL IMHO - YMMV
