So...bottom line...I shift into 6th at 65 MPH and back to 5th if dropping below 65MPH. After my in process stage 1.5 work is completed maybe I will reconsider.
I'll bet you still ride pretty much the same as you do now. I don't mess with 6th gear until I pass 60 mph, I can ride 60 mph in 5th gear and get great gas mileage all day long.
When I reach 60mph i shift into 6th gear. I have the FuelMoto stage one including the ss head pipe. The trike runs great like this and my fuel mileage does better also. Thats two up and lighty loaded.
