I have a complete stage 6 set up on my aerox. Im trying to find the correct jet to use for my carb?. Also wondering if anyone could recommend a good set up for a 21mm dellorto race carb. mixture screw for e.g! and the silver screw with the spring on it , what does that do?. and do I need to alter that at all?. And on top of that what would cause my aerox to delay on kicking in to its power band. If I hold the throttle for a little it will go errrrrrrrrr BOOOOM like it just fires off rapidly sharp like the fuel/carb isn't set up correctly.
