So I picked up a new front and rear sprocket for my bike. I was told it was better to get a 520 chain. So now I have the thing pretty much ready to go and I went to put the chain on and it doesn't fit into the front or the rear sprocket does this mean I should go with a 525 chain instead?

520 Chain on a 07 gixxer 600

Did you not buy your sprockets and chain from the same person?? It's best to go 520 conversion all around. Return the sprockets if you can and get new ones. I would recommend a +3 (46) in the rear, or if you want even shorter gearing a -1 (15) in the front and a +2 (45) in the rear.

I went with a +3 rear (stock front) and the DID ERV3 chain (520 conversion) and it feels like a whole new bike!!!!

u need the sprocket to be of the same pitch.
Your bike is gonna rev much higher than stock while cruising on the highway. Top speed is also decreased
What do you mean by shorter gearing?
I had assume -1 (15) in the front and a +2 (45) in the rear would be the exact same as +3 (46) in the rear
Yep. Love the new gearing! Top speed is 282 (gps) bouncing off the rev limiter and DAMN it gets there in a hurry now! Before it was so dead in 6th gear, you could never get to 303 unless you were going downhill with the wind at your back =(
You can check on http://www.gearingcommander.com and see what your bike says. For my bike a -1/+2 was the same as a +4 in the rear. Top speed with a -1/+2 is 268 and top speed with a 0/+3 is 280 =)What do you mean by shorter gearing? I had assume -1 (15) in the front and a +2 (45) in the rear would be the exact same as +3 (46) in the rear
When my speedo says 172 i'm doing 140 (gps), and at 140 (gps) it use to say 153 from the factory! Time for a speedo healer =)

+ fuel economy!
I haven't noticed a change in fuel economy at all. On my 5th tank now. 220ish (gps) before the fuel light comes on, same as what I was getting before, and if anything I'm pushing it a little harder to play with the new "power" and test the new tires!!

Im at -1/+2 on my R1 and havent noticed any decrease in fuel economy.
On the topic of reduced top speed:
Yes, there is a theoretical decrease, but from a practical perspective, my top speed is probably higher now at the tracks I go to given that I reach my max (265kph actual) ALOT quicker.

I am well aware of what my top speed is. With the sprockets I currently have now, I am GEAR limited to 265 kph (redline in 6th), not aerodynamically limited.
