Hi Guys, I just got a low hour Rotax 503 for my kitten project. It came with a pair of Mikuni VM34's. I have only run Bings before, an "84" on a 277, and a "54", (single) on a 377. does anyone have any experence running Mikuni's on a 503? Jetting info, and/or silencer/airbox Ideas would be most welcome. I ran across a 503 dual carb kit in an old CPS catalog and this may be one of those setups. The Wolf says they are "superior". I have a pair of Bing "54"s in good shape and I am used to them. Any information would sure help the decision on which pair to use. thanks
