01' FMF fatty and powercore 2

Post by FZ1426 »

I'm thinking that if a 170 main jet is standard (with the long joggled silencer) then with a fatty and the short powercore 2 a 175 main should be about right (sea level to approx 3000 ft.

Anyone concur?

If it blubbers lean it if it pings richen it, there aint no specific jet per mod, its all about what your motor likes.

Thanks, I'll answer my own question.

It took a 175 easy even at 3000 ft. and 80 degrees f. Probably could go even richer but it feels perfect now...

yeah plus about the time you think you have it tuned a storm will move in, the temp will drop 20 degrees and it will run totally different. Lots of other things factor into the equation, like ambient air temp, mix ratio, fuel used, filter cleanliness, weather it's hanging to the left or the right, engine load (how fat the rider is) and mechanical wear. Unless you are racing, if it starts on the first kick or two and doesn't ping or bog; fugit ride the bitch.
