I changed my Gianelli extra v2 to Pro Replica and after that ive been running in to this issue. So it started up nicely, moves nicely when just testing around my neighborhood with half throttle. Then i went to give it full throttle and it just starts stuttering and wont just take off. It stays stuttering on full throttle doesn't matter how long i keep it. It just goes the same speed and sticks to it. I am going to work on it this week i'd like to have suggestions from everybody, i'd assume its too big main jet. My whole set-up: Stage 6 Streetrace 70cc Stage 6 Pro Replica 19mm PHBG + stock airbox without snorkel Malossi multivar with 3x 4,5 and 3x 5,0 so 4,75g Red big spring (Malossi) Malossi fly clutch, with the yellow springs from here https://gyazo.com/15c6049a450991b864161a3614f9919f
