Anyone have a picture of a 4s vs 2s dyno curve?

[Casper250]

I remember seeing one in a magazine comparing a 125 to a 250f. Was wondering if anyone has seen one of a 250 vs 450f?

Here is another comparing a YZ125 to a YZF

Thats what I was looking for. From looking that the FMF dyno runs, is it true that the 250 2t makes less peak HP then a 450 4s? I thought the 250 2s was closer to the power output of a 450 4s then the 125 is to the 250f.

Off topic, but geeez... that write-up was a joke. They didn't have anything good to say about the 125... it's like they have stock in the 4 strokes.

I put up one on this site, look for dyno curves.

2 strokes dont compare with 4 strokes on the track or dyno-they have the conversions wrong

it should be 400 4 stroke and 200 4 strokes to make it a little more equal.
