Now have a few of these for the rest of the FCR's

As a straight swap they didn't improve power but they have upset the fueling so until I get that sorted can't comment on over all effect - regardless they aren't detrimental , look pretty and you can hear them whistle too
I then got 50mm versions and done two of them in the middle
Just forgot to take a photo of them hooked up on the bike

It's mental, I understand the science behind it ... But to actually see it... And some of the rarities you do have... Fwoar lol
