FMF Power Core IV and carburetor settings

Buddies,

i've just installed Power Core IV and have to say

it has very deep loud sound (and maybe

"substantial bottom end power increase" :) - i'll try) - very impressive.

but how did you tune your carburators after

Power Core IV installation? Jets, settings, etc;

richer or leaner?

I'm afraid to overheat the engine.

Thank you a lot.

I used to run an FMF IV on my 99 WR400. It ran beautifullly with stock carburation with only a minor adjustment to the fuel screw. Now my Big Gun exhaust on the same bike, that's another story. I still have not got the jetting right!

PS that FMF was loud but the top end was huge!
