Hi Guys, I have a 50V with a Malossi 62, I just installed a 19mil dellorto, idles great but when I open up the throttle its like its not getting enough gas. the jet it came with was a 75 to small? should I go up to 80's range or higher? I had 75 jet in my 17 dellorto and was fine. Also do you have to change the needle setting? its driving me crazy, rides well when not a full throttle !!!!
