Anyone have some baseline jetting specs for 98 rmx 250

[dufrain]

We just got a 98 rmx 250. It has a fmf burly on it and has been recently rebuilt.It has the keihin. It starts easy enough but bogs at high rpm. WHen its shifted into second the mid range hits good but when it hits high rpm it bogs and runs bad again. It sounds to me like it needs a smaller main. I just need some jetting specs that are close ,I dont know what jetting is stock but i do know the former owner was playing around with the main.Thanx

Go to Pro Circuit and click on jetting specs. It will give stock and recommended settings for most bikes. Click on the year in the bottom left corner.

Did you mean you have the Gnarly (instead of burly) pipe? The FMF website has jetting specs for 98 RMX.
