After putting about 1000mi on my new 1995 CB750, I've decided it's geared a little too "high" for my taste. So, I ordered a set of sprockets (14F/39R) to replace the stockers (15F/38R). This will give me about 10% more RPM, and rear-wheel torque, in any given gear at all speeds. The pair of sprockets cost $61 delivered, from www.sprocketspecialists.com I've done final gear-ratio swaps in a car, and I think I know what to expect. The only cons I can think of are: reduced top speed (supposedly rpm limited to about 128mph stock, but I don't care about top speed), and reduced gas mileage. The sprockets are due to arrive Monday, I'll do the installation myself and road test it as soon as weather and work permits. I might just do the front at first, that will give about 7% more rather than 10%.
