Gsx 750e air box boots

[tomahawk]

Hi,does anyone know where I can get 1981 GSX 750e Air box boots in the UK? If not who is the cheapest dealer in the USA as postage is prohibitive.
Also :- my GS is fitted with a 4 into 1 Marving exhaust and is on standard jets,will I need to increase the size and by how much?
I have no data on the GS as it was a non runner when I bought it.
Running standard air filter.
Thanks for looking. Ian.

You can get them from Robinsons Foundry. Don't order them over the Internet - the part number is wrong. Give them a ring, they have the correct part number written in their parts book. This thread explains how I found out:

You won't need to rejet for your Marving though you might have to tweak the mixture screw - use the fastest slow run method.
