I'm now looking for a set of 4 ITBs, possibly bike, and need to have a butterfly of at least 42mm, I also would like to know what they are off if possible? would be a nice bonus they were fitted a st170 manifold too

Ive got an ST170 manifold available

Whats the manifold? stock or something else?

Hi yes its standard manifold, it did have Suzuki GSXR ITBs on it but we used them on my sons car.

For ideas have a look at DanST

Suzuki gsxr 750 srad throttle bodies can be easily spaced apart to fit the standard st170 manifold.
