FLANGE

[pork]

Jus a quickie, bike carbs all cleaned up, got flanges,
Now, bike carbs are 45mm, inlet on head is 30x33mm.
Should I connect the two with a tapered to fit pipe, or can I take the easy route and just use a 45mm tube to connect it up?
Beings its gunna be pressurised, I wasn't sure if the fact that it won't be a flush fit, it might cause some sort of restriction, or turbulence, or am I worrying about nothing?

You dont really want a step in the tract eh neil, 38mm tubes and radiused edges maybe ?

Dam it

No easy route for me then

Would it effect quite badly then if I didn't do that?

I suppose if I'm doing this I might as well do it right ay?

Cheers
