Are one-way vacuum valves necessary?

Are one-way vacuum valves necessary?

Hey guys. I’m thinking of replacing the vacuum hoses on the Speed Triple. The ones that’re on it have one-way ball valves but, apparently, later model Speed Triples don’t. I’ve never seen valves in the vac hoses before but this is my first injected bike so I don’t know.


Thanks, Mick.


Incidentally, I’m considering replacing them as the bike is idling at 2k and I’ve found one crack on one of the hoses so there could be more.
