I am considering swapping my twin 40's for bike carbs, engine is a 1.8 zetec running ignition only control via GEMS what would be the best carbs and would they need re jetting ???I know a new manifold will need to be made done this already for an injected 2.00 zetec using carbs a tb's

Anything 900cc + will be fine. My fav's for build quality alone are the fireblade carbs.

earlier ones dont have a tps if your ecu needs one ? So if you need one make sure its got one.

Mods include drilling the jets out and maybe raising the needles ect loads of info on here for specific carbs.

--------------------------------------------

So whats up with the 40's ?

Mine are off a Honda cb600 hornet drilled out mains to 1.55 and seem fine. Mine is a 1.6 pinto however.

I've got some off a kawasaki ZX9R. haven't used them yet though.... they have TPS already on them, and a few peopl eare using them on 2.0 engines

Silvertop 1.8
ZX9R carbs on homemade manifold
Megajolt
2.0 cams
Set up at Bogg Brothers (superb)
120 bhp at the wheels.

Plus I reckon it does over 40mpg. Before I had them set up it struggled to do over 20!

zx6r carbs not fitted yet but Chester sportscars swear by them.

coozer do you have a map for your setup i am looking for something for my new setup.

I'll second ZX6R's. Work great on my 1.8 and 2.0 Zetecs
