This,
may look to most of you as quite banal.
That is the intention.
This rather nice inlet barrel looks bog standard, it's even marked "Triumph" like the original one.
This is where size DOES matter.
This one cures all the problems of the original ones, and if you REALLY REALLY have to use it for EFI, you can put a whopping butterfly in it.
Nobody will ever know or suspect it's been messed with, unless of course they happen to put the original one just next to it.
No more worries for higher power, over-richness or uneven metering.
