Going fast has never been so easy, say goodbye to hard starting, hesitations and flatspots.  These Mikuni TM38 non pumper type carburetors have for decades been the popular fix for all your old stock carb issues and look great whilst also giving you an even bigger performance improvement over the stock Dellorto.

The kit includes: Two pre-jetted TM38 Mikuni Carburetors. A pair  of  nylon lined throttle cables and a new twin pull throttle (where the black throttle housing can be swapped out for chrome on request). If you do advise at the time of ordering that you require a special cable length we can in most cases do the changes at no cost. This only applies to a request at the time of purchase. As there are no locator recesses in the Ducati manifold section, our mounting boots will not suit and you will need to source some Turbo Hose or fuel line for your new carb connection to the cylinder head. There are some POD air filters available for these carbs along with a listing of all other accessories, found when selecting TM38 off the TM Flatslide (non-pump) drop list in the main site menu on the left of the screen.

The jets to make this carb operate on Ducati desmo 860 and 900 engines have been fitted and there are spares for fine tuning the main jet circuit doing WOT tests. Climate, altitude and fuel density from different octane fuels all have varying effects on final fine tuning as does cam, exhaust and cylinder head porting etc. For this reason, we have included what we have found to be a range of jets to allow you to tune to most variables using Australian fuels.

At Mikunioz, for the last 30 years, we have been constantly checking and where necessary upgrading our jetting specs as fuel quality changes. Regular fuel in the USA is 85 octane or 91 in their premium brands which have numerous additives and blends added (basically smells and drys like wood varnish) which results in a totally different jetting spec and product performance. This carb as supplied from the factory will never work on this bike and requires a total re-jet which is done in house at Mikunioz prior to delivery with jets to suit your location anywhere in the world.

You will instantly experience better throttle response, improved acceleration, increased horsepower and torque.
