Many times I have dismantled a Mikuni VM carb and no matter what the size or configuration, it always strikes me that they are all that they need to be without any complications.
Last night I was working on a VM from one of my cherished but now dismantled 70s Suzuki TS125s, these bikes really show how little you need to produce an enjoyable and cheap two-wheeler, although as I remember, not very fuel efficient!
All that is needed to improve performance is a bigger VM and larger ports,it is surprising how much like the contemporary TM125 the major components are, unlike the more modern TS and RM models!
I was surprised how clean this particular VM was after years of use and storage, but there was the usual treacle residue in the float bowl prior to cleaning.
The carb is now in the pile of NOS and refurbished bits waiting for the day when I rebuild my 1975 TS125A
