Any experiences in tuning with Dellortos?

Post by TinSoldier on Fri Apr 23, 2010 8:19 am

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.

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.

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