Hi! my cousin bought them a superjet 701 61x and it does not work well to read the post on the forum I understood that we had to put it back with 1 carburettor because presently it is 100% stock but with 2 carbu 44mm but the time that I receive them pieces we will miss a jetski event is that someone would have jetting specs that I can install for the weekend

Thanks

Stock 38's run 70 pilot with 130 main with the same pop off spring. I reason that your pilot is too big. It's hard to say with 44's, not sure how that translates from 38's when converting. Top end the stock total fuel flow is 200 with both jets going and you have 235, so you probably have too much fuel there too.

Yah. Agree With what bernard said. Stock 61x only needs about 200 points of jet per carb on a dual setup. Basically Main + pilot = Top end jetting.
120 pilots (dual) is way too fat for a stock 701. You would need a SERIOUS motor to eat 240points of pilot. For a stock motor you should still be close to the stock dual38 jetting.
Probably a little bigger jetting all around due to bigger carbs, but not much.
