Sherpa T 340 give Dell'Orto VHST a try, spec's jetting

[pschrauber]

The carburator of my Bultaco Sherpa T 350, model 199b is retty

worn out, the slider rattels around, a lot of whitchpee has left

its tracks inside the bowl and the small plastic filters are cracked.

Time to get a new carb.

I have seen some Bultaco Sherpas, 199A and 199B models in photos from

the Spanish Zona Trial and Todo Trial sites, fitted with

Dell'Orto VHST carbs. Has anyone did this here in the forum too and

have the spec's for jetting?

This is the italian atomizer in a picture:

Any recommandation or hints?

Oh yes, it is a carb with a flat slide!

Don't know where or in which events you ride but "I Think" the flat slide carb is illegal in AHRMA events.

I think you will find they are using the PHBL dellorto as the flatslide is illegal for their competition. I have a PHBL on my 325 and it runs fantastic, 36 pilot and 116 main. My dellorto is a gasgas genuine spare part so you can run a gasgas throttle cable and throttle.Hope this helps.

Both of You are right, the VHST carb would be illegal by using with the Bultaco in a AHMRA events. I just looked up the rules here in Europe, (Germany), here it's the same. So this carb would work but it's not allowed to mount him, OK.

Actually I got my eyes to this model by a page of Todotrial where this model is shown exactly for classic bikes as I understood.

BTW: My understanding of Spanish is very very poor, here is the text:

"También los famosos Dell'Orto están ya disponibles en TT Shop. Ideales para restauraciones y preparaciones de clásicas, ya que hay modelos que se utilizaban en la época, como el PHBH 28 o el PHBL 25, con lo que superan las verificaciones técnicas de las competiciones de trial para clásicas. También está disponible el novedoso VHST 28 mm de compuerta plana, que mejora el rendimiento de los clásicos de compuerta redonda."

But maybe my enthusiasm has made me blind for the real facts.
