You should shift when your bike is making a lot of noise and not going anywhere.I ( my dad) rebuild my 125's about every few months. But i ride 3 days a week. If you omly ride it every once and a while you can go longer.

Where it says "omly" its supposed to be only.

two stroke bikes are made to be rung out to be wide open all t he time. just shift when the bike not picking up speed at the gear that u are in and the re-build i re-build my bike every 4 races and that is practicing 2 times a week and racing on the weekends
