I was changing my sprockets and chain and I noticed that my countershaft sprocket is not 17T it's 18T. I also noticed it was a bit lose. I thought the stock gearing on a 09 Gen II was 17/43?
 
If I remember right gen1 17/40 gen2 18/43

You are correct sir 2x.

Dropping to a 42T in the rear on the Gen-II, got 52 mpg. :thumbsup::thumbsup:

Not bad for a busa.
