[whodat]

Saw an UK dirt bike test on the de 200 and they said it ran weak only to find it had the same pipe as comes on the 250/300. After putting on the correct pipe they said it made all the difference in the word.(I cant find the article now)

My 05 200 DE has fmf gnarly #0250-49 and their site calls for a 0250-55. I have tried contacting fmf via e-mail but no reply yet! Does anybody have the answers? MY 200 is pretty weak on bottom and has a short spread of power, not a lot of rev.
jetting is 176 main, JD kit needle in middle,45 pilot, air screw 2 and 1/4
elevation is 1500' and temps from 50 to 80 this time of year.
only mod is a power-now wing that I bought to help my problem which it did only slightly on bottom but mid got much better! my biggest complaint is it just does not seem to make enough power down low to chug and claw its way up much of anything, lots of clutch required. I know its a 200 but jeez!
