I found some airfilter kits to fit my Delorto DHLA 45's.
They are stainless steel, and have a K&N style filter.....different to the picture on the box.....that was how they used to be.
The airfilters are 3" tall.
I bought the carbys brand new back in 1992, and never got round to fitting them....thats going to change.
I'm thinking about making some small velocity stacks to fit inside the airfilters......wait n see.
