I think on your chart with the 3 different outputs @ 3:14 the white coupler was supposed to be yellow line right? You had yellow line as green couple. Reason I say this is yellow was the hardest hitting according to dyno chart which would be the white aggressive coupler?
@17judd17
@17judd17 Жыл бұрын
I was expecting the same, however the dyno showed the green coupler made more power down low than the "white hard hitting" one.

I want to spend some more time testing and I feel it is more of a benefit for the 450s but the twin air system will give good gains on the the 250, close to a full hp in areas of the curve. And just to clarify , my previous comment was in relation to taking the air box cover off completely, yes doing this sees gains on the dyno

Yeh, I heard the bottom to mid power is less than my '19 but a tad more on top. I'm guessing they just changed the cam profile a little. I rather have a healthy bottom end for the Harescrambles I like to race. But adding more on top would be great

Have you dyno'd the 250f? Also, would have been nice to test/compare without the cover on. I know just cracking the cover open and quickly reving it, it instantly ducks the cover down. Has to be restricting air flow. I'd bet that would make power difference. Thanks. Love real substantive provable numbers. Your new sub👍
