Vic,
A member here had converted a '78 cyclone to dual carbs a few years ago and then sold. Here are some pictures. You can PM him and ask about it.

I almost fogot, another member, flames4555 restored a '76 Cyclone and added dual carbs.

Yep...that was a cool sled!

I only ran it once and it seemed to run very good. I used 70's Liquifire jetting. 70's LF carb adapter plate along with the air box.

It looked stock when I was done.

That thing always started 1st or 2nd pull...nice sled.

Hopefully when I get up north there will be enough snow to get Tuckers ( my Grandson ) 78 Cyclone clutched, that's the one we redid the engine with dual Mikuni's, & a lite Polaris track & suspension.. there should be pics on here someplace regarding the build..

Side note ....... Ed Kruel had a Cyclone with dual carbs back in the day. His son and my classmate Tom used to run it
all the time. In the early 90's is was still in the Horicon area but has since disappeared.
