Good morning lovers of NOVAROSSI I already have my new MBX8 and I am a beginner pilot (6 years old). I bought a P5xlt 9901-41021. I already finished the break in (2L). Someone may help me adjust the needles. I live in Vigo-Spain. use venturi 6.5 and nitro RUNNER TIME 25/8 and spark plug CTO6 and the track where you drove is fast and with a lot of grip. MANY THANKS
