Katana Owners Club U.K.

Trying to work out what carbs I have for the collection of bits that will form the basis of my Kat Thou.

If anyone has a set of VM32’s close to hand I could do with some dimensions particularly the engine side bore. Photos as well would be fantastic!

I have a set of VM’s that were supposed to be the correct ones, but I’m not convinced. They measure 36mm diameter on the engine side.

I have a set of VM33 smoothbores that have been cleaned up and may use them instead, or do I sort out a set TM34’s

Would prefer to run with a full airbox and obviously a 4-1. I want the Kat to be useable on normal roads.

Carbs are all wrapped up but external measurements on air box side are 55mm and 40mm or engine side

Cheers for those measurements. My VM's that I have measure at 36mm internal on the engine side. So I assume they're VM36's.

there were quite a few vm32 sets that were bored out to something like 35 or 36mm for racing, but im not sure on the exact details.
