I'm about to order a set of TM-Pro 41 carbs for my 800* motor and have a couple of questions for you guys. I've looked through most of the info I could find on the board and have come up with a starting point for jetting as follows;
main jet 250
pilot jet 30
needle jet Q2
jet needle 6FJ41
throttle valve 4.0
float needle valve 2.0

I'm assuming if I go for the "custom calibration" option I can order the carbs with these specs...

Is Sudco or Power Barn or? the place to order Mikunis from?

What kind of selection of jets, needles etc should I order to have something to tune with once I get the bike running? I have nothing now.

*05 800SS motor with BMC ported/big valve Alazzurra heads 800 cams 11.5/1 CR? LoudBike exhaust trackday/race TT2

Hey, John:

I started with the same setting that was used in my 853 motor (F1 cams):
Main: 250
Slide: 4.0
Needle: 6DP4 (2nd pos from bottom)
Idle jet: 32.5
Float needle jet: 2.0
Atomizer: 389P8

With the TT1, I ran a smaller (1.8) float needle jet with the Mikuni DF52-176 Dual Outlet Pulse Vacuum Fuel Pump

..The rest of the final jetting on the TT1 is too NCR #7 specific, although with the exhaust system, you may - like me; end up with a very small pilot jet (I'm using a 12.5). Palmer told me earlier this week that he was running a very small pilot with the 41s as well - with a needle that had an even finer taper.

I've been buying from Sudco.

Hope that helps..
