Hello first of all I am like you vlt. remembers new here in the forum. But to get right to the point here my question: do you notice when you throttle the 4-stroke models of the EXC series a difference? If so in what way? Does the acceleration slow down or the top speed? How can you throttle them with 18? On 34hp or on 18hp? And with 20? I know there are a lot of questions at once but on the web I find just 0 info. Already at this point a thick THANK you .
