Jetting DCNF 42 on Beta Volumex

[petarn_vx]

Hello Guy,

I want to use a DCNF 42 on my Beta VX and I am not quite sure about the jetting.

The Engine hast the following specification:

Ported and blue printed head with standard valves
Inlet cam from Beta 2.0ie, exhaust standard.
4-1 Header
60mm exhaust with straight thru muffler
facet silver pump

I wanted to start with this (But I think its way off):
Chokes 29mm
Aux Venturi 3,5
Emulsion tubes F24
Main jets 155
Air correctors 165
Pump jets 45
Idle jets 60

What is your opinion about this setup?

Thanks in advance !

Best regards
Peter

Peter, hi

it's not way off!

Choke 29 OK
Aux Venturi 3,5 OK
Emulsion tubes F24 OK
Main jets 155 maybe too rich go 145 or (150 on gasflowed head)
Air correctors 165 too rich go 180
Pump jets 45 go 50
Idle jets 60 OK
