45 Mikuni HSR set up on a 95" TC

[todd10]

Hello,

I just converted my 99 RK from the notorious Magnetti Crapolli efi system to a 45 Mikuni on a SE big bore intake. Also the bike has SE Performance heads, se perfect fit push rods, se .257 cams, Forged se high compression pistons, se adjustable ignition set on curve 3 with -9 advance and set at 6k rev limit. Just wondering before I go to a lot of dyno time if there is good general rule of thumb on the size of pilot, needle and main for this set up! Also it puts out 200 psi static compression 1 & 2 with the throttle wide open!

Good start is the 25 or 27.5 pilot and 190 main, needle clip stock. Be sure to check that the accelerator pump spray is correct per the manual (some like to spray right on the needle, others favour just missing it to the front).
