Amal Mark II

Hi, Anyone running twin Amal MKII's (2xxx-300, 301)? If so, please offer up your setup, configuration, mounting, jetting, etc, etc, etc.

Thanks so much,
Petr

Got this info through net trawling so it ain't mine and I ain't tested it


Hey Peter
I was serious for certain. Also thanks for your help along the way with my mik/primary etc.
Its my turn to pay it back and in glad i can help so Here is the info. It's not mine but I gathered it in my quest to do the mk11's but ran short on funds. The other issue for me was my supplier is in England and I'm in Australia making development and testing a long process.

"These are the settings I use on the Amal Mk2 34mm Smoothbores fitted to my Commando race bike (4S camshaft).

Main Jet 270
Needle Jet .106
Throttle Slide 3½
Needle 2C3 - middle position
Amal velocity stacks fitted, no air filter.

The major improvment came from changing the needle, and I'm indebted to Dave Nourish for his advice. You will find you need to use too large a main jet with the standard needle, 2A1 (I think), and this messes up the rest of the carburation. Note that 2C3 needles are longer than standard and should be shortened to 2.75" by grinding off the tip
