930 Amal MK1 upgrade (Premier)

To those contemplating new MK1 Amal carbies.

I ordered 2 new 930 concentrics from Amal and received the following offer to upgrade to their new Premier version. I have accepted by the way!!! Looking forward to fitting them to the old tart. RR


"I am writing to customers ordering 30mm Mark 1 carburetters because we will shortly be introducing an improved version of the Mark 1 Concentric carburetter for four stroke use which we call the Premier version. It includes all the recent upgrades such as hard anodised slide, Stay-up float and aluminium needle valve. It has also been modified to use a new design of pilot jet.

The new jet screws into the body in the opposite position to the pilot air screw and replaces the pilot bush previously used. This positions the jet in the same position as the pilot bush and in the optimum location for four stroke use. The jet can easily be removed for cleaning and has been designed to tolerances so close that the jet can be replaced if required without the need to re-tune the idle circuit. Everybody who has used the new carburetters so far have reported noticeable improvements in idling and low speed running. Mileages of up to 1500 miles have been reported so far without problems.

The carburetter is currently available in 30mm only for 116.00 plus shipping (and VAT if applicable) with a 2 year guarantee. This is a preliminary offer because in exchange we would like to hear any feedback you may have on how the carburetter performs."

Looks good Rod.
I like the screw-in pilot jet.
Time to upgrade???

Does this mean the end of poking around with guitar strings then?

Guitar strings may well become redundant one day. RR

I hope that for your 200 odd quid you get your twin carbs to idle as well as my single Monobloc.

Certainly sound like nice carbies.

Cheers,
Neil.

What Can I Expect?

Hi guys,

I actually just ordered a 930 premier but before I bolt it on I was hoping I could get some advice from the group. My concern is as follows: for a 1972 TR6R, the book says 3 1/2" slide is what I need. But, the new 930 premier doesn't seem to be available for purchase with a 3 1/2" slide. It seems like I have to buy the carb with a 3" slide then purchase the 3 1/2" slide separate (which is another $50). I'm wondering-all things being equal--what I can expect in the way of idle/performance if I run the new carb on my Tiger with a 3" slide rather that the 3 1/2" slide the book calls for.

Thanks!

You can expect a rich mixture,especially at just under 1/4 throttle.
Just file the cutaway 1/32" bigger.Change the angle to make it a 3-1/2 slide.

The premier carb is built with the components you request to be fitted,there is no extra charge at all from proper suppliers.i just bought a pair with the parts I wanted fitted.They were bolted on,air screw set at 1 turn out,tickover established,and then up the road after a first kick start.running better than its ever run.I had replaced a set of MK1s that were 10 years old.Perfect and worth the 260 a pair I paid

I agree. I just put one on my T100C. Brilliant! Wish I had done this years ago. You won't regret.

Amal Premier Carbs

I have to agree with those who have posted positive results after fitting these. I had been chasing uneven idle and mixture variation with my old carbs which were original. I replaced everything short of re-sleeving. I did the math on throwing more money at the old carbs, or just buying the premiers. I am so happy I did. My guess is that buying the old standard Amal Mk1s would have produced the same result, but the hardened slides of a new alloy and the stay up floats are realy reasonable upgrades worth paying a bit extra for. We should count ourselves fortunate that we can buy these over the counter brand new at such reasonable prices. Many other vintage bike owners have to go the re-sleeve and repair route or spend big bucks for mint or NOS spares.
