I want to replace my carbs, Should I get new Amal or Makuni?
And why? On a 1974 T120V...

Amal have a bad reputation. Unless you are build a to spec bike I would go with Mikuni or Keihin PWK.

I have run Mikunis on several bikes over many years and am very happy with their performance ,problem-free nature, and durability. I have a new Amal with the hardened slide (not chrome) and stay-up float kit on my 73 TR7RV and am very pleased with that. I got it direct from Burlen. I can't find any input on the new Wassell Amal-style carb. In general, I like their products a lot. The Amal Mk2 is similar to the Mikuni. My buddy is going nuts trying to tune his BSA 650 with the cheap Asian Ebay carbs. Mikunis don't mate up with stock air cleaners. Mikunis have a richener, not a choke, and mine start well in cold or wet conditions. Bob

The latest Amals, especially the Premier carbs, which I have on my T120 are very good. After 1000 miles there are no marks at all on the hardened slides, the pilot jet comes out for cleaning without removing the carb and float levels are easy to set with the stay-up floats. They worked straight out of the box, just set the idle and go.

How much did those new Amals cost and did they fit as a direct replacement for the old concentrics?

They cost £109.99 each here in the UK.

They are identical to the old concentrics except for materials and the new pilot jet so they are a direct replacement.

The only problem I ever had was when a small piece of the slide on a 441 Victor broke off and went into the cylinder. It rattled around in there while I rode it home. Every once in a while the piece would jam in the exhaust valve and hold it open. I would coast to a stop and when I kicked it over the piece would fall out and I could start the bike and continue on home. A rather bizzare carb failure that was because of vibration fatigue. My fingers still tingle from that bike and it has been 20 years.

Most of the "bad reputation" is from those who are unable to properly clean one, and install a rebuild kit.

The rest is due to wear between the main body and the slide, which can be cured with a re-sleeve and new hardened slides.

I've known of bits breaking off when the slides are very worn and get thin. I can't imagine it happening with the anodised slides which look like they will outlive the carburetter. If I wipe them over they are like new, no marks, no grazes, no scuffs!! After 1000 miles a standard slide or a plated slide would have already acquired some scratches and wear marks.
