OTOH, under ~2.5k doesn't work either because of the definite complaints on her side (strange noises like pinging). So I use a pretty narrow range, which also makes engine braking kind of useless (except for some declines), so when I learned about coasting I embraced the idea wholeheartedly  |
Teresa being a big single cylinder engine makes it a little special regarding rpm potential and in the bike world (I use to own a big single : Suzuki Freewind 650 cm3 personal best a 4 liters to the 100 kms with a +1 font sprocket and a worn chain)
Anyway, best efficiency is at peak torque, I bet peak torque is around 4,5 to 5K and that the engine runs around this rpm at 70 mph in standart trim.
Personnaly, I wouldn't want to lug a big single at to slow a rpm cause it spells failure in my book.
