im still worried about really romping on this motor so i'm basically 1/8 to 1/4 throttle max.
i feel like it shifts from 1rst to 2nd at about 5mph. 2nd to 3rd at about 15 or 20. Once its in third it just keeps getting louder to go faster

It does feel like it coasts ok once up to 45 or 50. ie I can let off the gas and it doesn't slow way down like if i held a car in gear to low.
