Is the purge system really needed on the rocket after modes

Hello,
Is the purge tank system really needed after modes to the bike have been done? What happens if it is removed?
Thanks

Not sure what you're referring to as a purge tank system. If you mean the fuel evap canister, which is an emissions piece on some bikes then yes, you can remove it. Just make sure you cap off any vacuum lines and connect the overflow line from the tank to the line leaving the canister to the ground. If you're talking about the radiator overflow tank, then most definitely not.
