k got my hands on a aerox 50 for stunting, just orderd ur recommended 70 set up for it, and was reading about the petral tank, if it a must do when wanting to wheelie for a long time? or is it a easy job?

yes, you need it for long wheelies and for longer work time while on 12 bar...

is it like a easy job i tryed to do it today, but i got bored when after i took the panels off lol

I´m not sure I understand the question but you want to know if you must change gastank?
