When I first bought my S4Rs, I immediately felt the need to drop to a 14t front sprocket, based only on reading all these posts. It lasted about 100 miles, and I switched back.
Now that my chain and sprockets were getting close, I knew I would change the gearing. But in the other direction. I have zero trouble pulling away from stops, but there are times when I'd like the gearing a bit taller so I can cruise at 85ish at comfortable revs.
So I went from a 15/43 to a 15/41. It dropped my revs in the freeway about 400rpm, which is ideal. I am not a super racer type, so I don't care about slightly slower accleration...my bike has more power than I need.

Decided to go with a black sprocket and a gold chain. It looks just pimpy enough, I think. I'm super happy with it. Only gone through one tank so far, but on a typical ride I seem to have gained about 3 mpg, and the motor burbles along more calmly. So I can keep it in fifth for 50-60 speeds, and 6th isn't quite an overdrive, but it's perfect for me.
I also added a Sargent seat. Only one ride on it, but it trasformed the ride and feel of the bike. Amazing. I have slight concerns with the workmanship, but it's amazing overall.
Thoughts?
