bike carb inlet manifold
hi all
the winter modifications have started !
one thing i was hopeing to do is to bring my bike carbs totaly in board so that the bonet fits over the filter (no big hole cut in the side) also to
get best flow possable to the head
will the carbs be ok that close to the block ? the inlet pipes will end up being about 1inch on the short side and 2 on the long side.
also iv heard from some that to get better flow you can reduce the angle on the inlet pipes a little ( taking the carb float chambers off level)
ass when on a bike there never totaly level any way ?
any one go some infor on ether of these subject would be great

I've got a set with dead level inlets, carbs spaced out they work fine with the float bowls flat
Bike carbs are designed to work at any anglewiththe fuel pickup low in the bowl
I eat to survive
I drink to forget
I breath to pi55 my ex wife off (and now my ex partner)

Mine are basically direct to head and work fine.
I just used the original ZX6R bike inlets bolted to an ali plate like this:

Inlet runners are about 2" but I have to use a thinner 65mm Pipercross and that is tight on the bay sides
If I used a upswept manifold I could put the 90mm one on

Yea I've started with an up swept one and guna use the90mm domed filter witch should fit inside nicly.
Just wondering how much I could sacrifice the float chamber level. Seem it's irelivent so should all be fine
