G'day mate.

Nice way to introduce yourself.

Do you mean the rubber inlet manifold/adapter between the carbs/injectors and the engine or the rubbers/bellmouths between the carbs/injectors and the airbox?

Those are FJ1200 manifolds presumably.

The FJ1200 uses the similar Mikuni BS36 carburettors. Stock jetting for the FJ1200 in the UK is 112.5 mains and 40 pilots. US jetting is 110 mains and 42.5 pilots. XJR1300 apparently runs 107.5 mains.

See how it runs on stock jetting, if it isn't happy I would suggest getting a set of 110s and 112.5s and seeing if it is happier.

Any decent parts supplier should sell Mikuni main jets.

Wemoto sells them, among others. They should be around £3 quid each.
