You have a 32 tooth sprocket. A 30 tooth would really wake your bike up.

My fuel mileage has been 38 mpg on adverage so far. Im going to lean it out a bit in the cruise range and see if I can pick up a few mpg's on the highway.

Okay...thanks.

I can't see why you need a 31 with that motor.

I had my old 88 geared down....I know how they act when you do that.

your bike has to be a real blast to ride. don't expect good mileage on your rear tire though. congratulations on your new motor.

On a Harley, that would be a top-gear run. An uncorrected run gives you what your bike did, on that day, no BS. No skewed numbers up or down based on correction factors.

Of course, I understand people who aren't blessed with great air would be bummin, but uncorrected is uncorrected. It is what the bike made. Period.

Anyway, nice numbers, can't wait to get my 120R...

Your Dodge diesels are turbocharged, they create their own atmosphere. Recording elevation, barometric pressure, humidity and air temp for a correction factor would really skew the results, unlike a naturally aspirated engine. As previously mentioned in this thread, top gear is usually an overdrive gear.
