Ok i know there was a thread posted on this somewhere in the archive, but i cant find it now...anyways just got a Weber 45DCOE, and was wondering what chokes, emulsion tubes, etc etc you guys/girls were running, or if you have the link to the thread in the archive, it would be much appreciated, (ps i DID search for quite a while but i cant find it...) its an 85, stockport 12A...please any direction would be nice...thanks!

pre-work bumpity bump...just looking for a baseline tune...ive got a book on webers and dellortos and it lays out everything for a base line tune on cylinder motors by cc per cylinder, could i use this and just go as if each housing was a cylinder....ie 600cc(ish) a cylinder? or is this not feasible....?

Me and another member run OER 45mm's, which are a stripped/racing version of the webers. He has 180 main, 160 air corrector, 65F8's for idle , and an F7 emulsion tube which I plan on running.

This link doesn't cover the 45 specifically, but the tuning tips will help.

I'm using these, but is a 12A Street Port, so 38 chokes would probably be better...

Idle Jets = 65F8
Main Jets = 165
Air Corrector = 230
Emulsion Tube = F15
Pump Jet = 4.5
Chokes = 40mm
Auxilliary Venturies = 4.5
Needle & Seat = 3.00
Fuel Pressure = 4.5psi
