I have just over 1K miles on the bike since building the motor. Did the first oil change yesterday with 900 miles on the build. Oil was very clean, nothing was on the drain plug at all. I was very pleased about this.
This bike is easier to ride than stock. Throttle response is very smooth, no surges or such. First four gears it pulls fine from any RPM. The other day was in 4th for quite a while on a twisty hill road, could easily pull out of a curve at 2000 rpm, and then up to 2700 rpm before next cover. Also cruise fine at 65 mph in 6th. There really is power everywhere. 5th and 6th do better if kept above 2400 rpm. If you grab a hand full of throttle above 3K you better be hanging on, it pulls very hard, very quick.
3/4 throttle in 1 or 2nd will fry the tire.
Have only check the mpg on the last tank. It was okay, 38.2 mpg. That said I had a good 30 miles of riding very hard trying to keep up with sport bikes going across the mountain on hwy 68 out of Tellico to Ducktown. That said I think at a steady interstate cruise I will be able to see 43 mpg or so, and similar on group rides.
Very happy with the bike
