which nozzle?
« on: April 12, 2010, 07:38:38 PM »
Hi all, I have a question about nozzles in carburetors.

i made my second bike, 2stroke 2 cylinder benelli 250 2c for race.
originally hee has 2  dellorto VHB 24, vith nozzle - 100.

The change about engine is:  no barrel vith chambers for slowmotion air, i got  dellorto NOS, 
instead of serial  exhauster  i got resonant open exhauster per cylinder,
and  expand of intake  channels in cylinders.

So: i take nozzles instead 100, 115,(compenzation for more air) and i dont have power.
i try nozzles 125, 130, 140, 145, and same problem.
my mechanic say  to i need larger carburetors, accurately dellorto VHB 30.

i understand that is bigger, moore soup, and all, but can I  combine something with small vhb 24, and large set of nozzles?

thnx,  Miljenko
