Chain: D.I.D sounds like the best/better quality, and since I'm changing to a smaller chain (520 vs. 525 stock), I want to make sure I get the best/better quality. It's a gold-colored chain which will match nicely with the gold rear sprocket. Btw, I have a silver/graybike. Also, although I'm guessing a minor performance difference, the weight is well over 1/2 pound lighter for a 520 vs. a 525. Perhaps it is more significant considering rotating mass. Lastly, price is less for a 520 vs. a 525.
Sprocket: Vortex, again sounds like the best/better quality, and they have a huge range of teeth sizes. It's a gold-colored sprocket, matching nicely with the gold chain. I'm going with a 48-teeth rear sprocket to increase lower-end power, but keeping with a 16-teeth front sprocket (stock teeth count). I'm choosing the 16/48 combo as a middle ground for what most people seem to be choosing, which is 15/48. I'm also just changing only the rear because I believe there will be less wear on a chain by only "upsizing"the rear sprocket, instead of"downsizing" the front. Seems to me that a larger rear-sprocketwill cause less wear than a small front-sprocket. Btw, I found a great Excel spreadsheet that shows the speed difference when changing sprocket sizes (Click Here). Lastly, I am changing both front and rear sprockets because I feel I should when a new chain is installed (btw, current chain is stock and has rust stains with 3600 miles on it - poor maintenance by prior owner?).
Any comments, thoughts would be appreciated.

If your looking for quicker acceleration then -1/+2 is the way to go. I've never heard or experienced faster chain wear by doing that, but maybe one of the other guys has. check this link http://www.sumofallparts.net/. this is where I buy my stuff and it runs around $150.00 for the standard -1/+2 and DID (i think) chain. They can also hook you up with colored chains and anodized sprockets to. I just ordered a yellow chain and black sprockets and its costing me just under $200.00 for the kit.
1995 FireBlade ( or CBR900RR depending on where your from )
my 00'r6 had a 530 set-up stock. chain never really stretched and i never adjusted it in 6500 miles. i'm thinkin about doin a 530 on the f4i for less chain maintenance. might cost you a couple a few horsepower. less maintenance and more riding time
