It is a 4 stroke . and not a 2 stroke - yes?
2's can be breathed on any number of ways and become go-fasters.
Not so sure about the 4 strokers. The impression I get from 4 stroke LIKE 50 owners is that they are s l o w! @33MPH max.
This needs to be well understood at the time of purchase!....not after!
