Amal to Mikuni conversion chart
« on: December 16, 2018, 04:29:11 PM »
  I had a book or magazine years ago which had a Amal to Mikuni jet conversion chart in the back.  You still had to do the testing to get the jetting right but it gave you a heads up and a good starting point.
  If anyone knows if this type of chart is still available, or can remember what book or mag it was in that would be a big help.

l'll see if l can find it online, l printed it off for my files. lt also has a comparison between Mikuni hex & round head main jets also. lf you google search 'Mikuni round head conversion' you may find it?

It's not much help I know.…  on my maico 440, just in terms of the number stamped on the jet, a MK2 40mm amal compared to a 38mm VM mikuni, the mikuni pilot jet is roughly 100% larger, the amal main jet is about 50% larger.

  Thanks, John, Ralph
                              I'm still hoping I will find that old chart among my collection of books.  At the moment I am going through all of my old Classic Bike and Classic Motorcycle mags. If I don't find it there then it'll be back further, I don't throw any on my motorcycle mags or books away so it's got to be here, right.

  Hi Pokey,
          Not exactly the same but close enough.  Thanks for your help.
