The Exup on the Gen2 is purely for noise dampening. It won't effect anything except the sound if it's removed 👍🏻 just makes sure to disconnect the cables from the servo under the seat too. Leave the servo in place that way you won't get any error codes and as far as the bike knows everything is still at factory spec, saves wasting £30 on a servo eliminator
Thanks for confirming this. I have an FZR1000RU and know that they run like sh#te if you take the exup valve out.
Just got a Gen2 yesterday and was a bit concerned when I started checking it over properly this afternoon that the valve had been removed.
I know I should have checked first but there-you-go. Looks like I got away with it this time for a change ..
And it seems it's got a Black-Widow exhaust, somewhere under all the corrosion on the headers.
