Need jetting help fast

[Awk08]

I have a 260 ok n mine only mod fmf plug chop looked good doing one tomorrow will post pics

I've personally jetted 3 different blasters with FMF's @ 1800'
and can assure you from personal experience, they require more fuel than a 260 can provide, even at this elevation.
here's my math............
FMF @ 260 @ < 1500' @ < summer temps = KOR top end rebuild.

Ok I was just going off what a member told me when I first bought the FMF I am going to pickup a 280 tomorrow before I finish breaking in the new motor. Then I will plug chop.

thats just it, I may be wrong too....@ your elevation, temps, and that exact engine.
I just posted my personal jetting experiences with FMF's, not what i think i read somewhere.
nobody can tell you an exact jet, or exact formula for jetting.

thats why we have these threads...

so you can see what other people who have actual jetting experience with similar pipe/mods, and have reported what jets worked for them, then you determine a starting point for yourself from there.

let us know what how your plug chops go

I am glad I saw this. mine was running a 230 at almost 1800 ft. I have fmf fatty and boysen reeds with K&n style filter. I definitely need to buy some jets before I put it back together.
