My setup seems rock solid now. Different powerband than my snappy 5 mil 876 I was running before but a tank of gas lasts about 1:15 when i used to get 45 minutes on old setup.

I'm building one of these for a FV-pro this summer. Do any of you guys run a OE 155 that can help recommend a prop/nozzle bore to start with? I also "plan" on running 44s for the time being where I see all of you are running 46s.
 
So when going up in carb size 46 to 49 do you have to lower the jetting most or the time or rise it a litte also. Sorry i know it's a off the wall question

This might be a bit late, but im running a oem 155 with a cut back 7/11 but also novi 48's
 
No I switched to 130p and 120m and bumped spring up to 115.

Hmm, I got that spec from Art but with a 95g spring and it seemed to be pretty fat. Just switched to a PFP and went back to 120m 110p to see what happens. How are you liking the new jeeting with the 115g spring?
 
Running fine. Much more crisp with higher popoff. I run a pfp wet and total loss ignition

Cool, I might have to give that a shot. I swapped back to the 120/110 but left the 95g spring in and it seemed to smooth out, which i am looking for the snap. I am going to ride this weekend, but I am leaning towards trying your jetting. Definitely looking for throttle response.
