I'm all ears on the ride /pipe report. It sure looks good.
It does look good. (Walt's Modded Pro Circuit Pipe) I have REALLY REALLY been waiting to try this pipe.... I know how the Fatty works, although it has been a while since I've ridden that bike.
I bolted my 165 kit on yesterday, and got one heat cycle in last night. Did another two heat cycles today, then loaded her up, and took her to the mountains with my boy and his little 50.
This pipe is pretty much exactly what I was looking for, but I feel like I'm in a bit of a unique situation compared to some around here... We all have our own riding styles, and this one fits mine.
What I love about the 125:
Running the bike WFO - reving to the moon out of a corner, then grabbing the next gear as aggresively as I possibly can. I love jumping 5-10 feet off little stumps, rocks, downed bikes, whatever....
Not needing throttle control like my 450 requires in the tight stuff.

What I don't like about the 125. It's in-ability to pull my fat 220lb ass up a steep hill, unless I'm ON THE PIPE. I can get the 125 over pretty much any technical hill, but the fast 3rd gear wide open hills, the 125 struggles....
How much I have to try to pull the front wheel off the ground, for a log or to try to improve my parkinglot wheelies...
After riding Kelly's 165 with the FMF Fatty, I honestly thought that it was too much on the bottom for my riding style. It was going to require me to change my riding style to much. I was amazed with the power from that setup, but was thinking a 144 was going to be my next purchase. After talking with Kelly again, he told me I was crazy to get the 144. He then reminded me I could get the 165, and "dumb it down" with a pipe to take away the gnarly hit. Walt recomended I try to source a Pro Circuit Pipe. A few months later, my kit shows up, and Kelly has the pipe on the shelf, waiting for the opportunity to try it out. I pick up my kit, and he offers to let me try it out, and of course, i agree.....
My findings with the pipe: Doesn't have a monster bottom hit like the fatty does, but still lugs and lugs, and lugs... In fact, I wish the bottom was just a tiny bit more with this pipe today. I do feel like right off the bottom, it is a bit fat, so leaning it out a smidge should make it perfect.. As my first ride, I wanted to be on the safe side.
I approached a loose gravely hillclimb about every way possible. I was amazed when i came up to the bottom crawling in first. About 5' before the hill, I'd hammer it, and it would just FLY, gaining all kinds of momentum while climbing a steep hill... The 125 would be searching for power had I approached it that way. Mid is smooth, and easily pulls the wheel off the ground. Top is still tons of fun. I don't know where these motors rev to, but If I had to guess, I would say this motor/pipe signs off about 1-1.5k earlier than my 125 of a stock pipe. This setup is still going to let my ride agressively, and have that extra umph to get me out of trouble when I need it. I will also be a better parkinglot wheelie-er
