Changing from 20% nitro to 16% nitro, help please.
Hi,
Im changing from 20% nitro to 16% nitro fuel (byron fuels, both of them) ...
Now, really i do have to mesh with the shims of my engine ? (Novamega SX12RE EV1) ... or its just put 16% nitro fuel and go to the track (previously with a little running inn ?).
Thanks ...
