After some very positive testing this year with Mikuni TMX 35mm carbs MB Developments are pleased to announce we have taken the plunge and now stock a full range of needles, slides, main and idle jets for the TMX 35mm Mikuni carb. We do not offer spares or support for any other Mikuni carburettors at present, especially ones not used on Vespa or Lambretta engines.
MB Developments have been using the flat slide Dellorto as the top of the range
carb for a number of years.
We have found when using them on vibrating Lambrettas that the slide wears and
can effect jetting.
We have not liked the 34 / 39mm carb because of the variety of needles and needle
jets available causing us a great big headache on the phone.
We find them overkill for road engines and their physical size is a waste of
time.
For this reason and a need for a better quality carb we have invested a great deal of time and money into the TMX carb.
MIKUNI TMX 35MM CARBS
The Mikuni TMX 35mm carb is nothing new it has been used on Japanese motor cross style engines for years, they were designed to give instant throttle response at all throttle openings.
They are physically smaller than the VHSA 34mm yet still easy to fit, they use
the same carb rubber as all Amal 28 / 34mm and the Dellorto VHSB 30 / 32mm carbs
which means there is no need to change your inlet manifold or carb rubber.
This carb unlike any others around DOESN’T use needle jets, all they have is a number of needles to set up the mid range making them VERY simple to set up!
The TMX can be fitted to a fast stage 5 cast 200 tune or any TS1 tune.
Because of the way they respond to throttle opening and more importantly flow air and fuel in flat out circumstances we believe this carb to be the best available.

More responsive at all throttle positions, easier to jet in than any Amal or Dellorto.
