If you want more bottom or rather mid range try the fmf fatty

Within the FMF line I’ve tried a bunch of combinations and the Fatty with the shorty gave me the most bottom end.

Also adjusting your power valve to hit where you want, makes a difference.

I'm running a pro circuit r304 silencer with a modded works pipe, I have stock 125 and 150 motors and mod motor 125. The pipe helped the stock bike a lot on the bottom and didn't take away much from the top, and even after messing with jetting i could never get it to run right with the stock setup.

There is recent thread on thumpertalk about a guy developing his 125sx. He said the Mikuni was his best bang for buck.

Does a fmf fatty run leaner than a stock pipe on a 04 cr125 ? I ask because it’s 39-43 degrees in the morning.  And I might be riding in sand not real deep tho.  I don’t want to seize it up.  It’s all last minute to get a ride in this yr.

The pipe might make a little difference, but a more free flowing (louder) silencer definitely will make it run leaner.

Keep a close eye on the plug between rides. Back it down (less WOT) if you notice that if the burn line is working its way all the way over the electrode to the plug body. And similarly as that color ring moves it's way down the porcelain.

Sand and cold temps… richen her up to be safe… then work your way leaner if warranted… lots of guys would sieze at southwick in morning practice when cold & freeway fast…

Every Fatty I know of had to be leaned out due to increased vacuum signal.
