Any experiences in tuning with Dellortos?

Hello, recently I upgraded the engine in my 71 Westy from 1600cc to 2050cc. Since I opted for a bigger engine, I decided to use a set of 40mm Dual Dellortos for fuel. After installation and checking everything to make sure I didn't miss anything. I got it to crank up. However it idles really low. I know you suppose to have certain sizes for idle and etc...Since I bought these used, I don't really know what the jets that are in there now. Anyone have experiences with Dellorto can help me. I am a little verse in carbs but it has been a while since I gotten back into air cooled. My last set was dual Kadrons but they were much simpler and over 10 yrs ago.

Thanks.

You need to get this-The Dellorto Superperformance Tech Book
It's a link to the book on Amazon

Thanks, I actually have that book. I was hoping someone who done it before.

What are the specs of the motor? I've never heard of a 2050cc? 88X84 stroke makes a 2044cc, but thats an odd sized motor. 92X78 makes 2074. 90X82 makes 2086cc i think. 94X74 stroke gives a 2054 or 2052cc. thats the closest i can think of, off hand. my interest has been tickled, lol.

To be specifically, it is 2054cc.

I think he means what size crank and what size cylinders are you running

2054cc should be 94's with a 74mm crank if i remember correctly. nice motor. good to see a nuther big motor rollin around, lol

I'll help ya build one if ya want. hell, go for a 2387 . cb sells a case clearenced for 86mm crank with chevy rods, and then get 94mm slip in cylinders .

i said i want to ride not break down every 50 miles LOL!!!!!!!! nah im going wih a 1915cc and mabe some wheelie bars for just in case you no what i mean lol,!!!!

lol, i had to try, . just go with slip in 94's. don't want to pull out any studs, or crack the case

94mm slip in i havnt seen those you will have to open the case if its biger than an 88

no, they are called 94 slip ins, because they fit into the same hole as 90.5/92 cylinders.
