i fitted a set to a T120 last weekend
Amal were quoting min three weeks to deliver a set of 30mm premiers , so i thought sod it i will give the Wassel`ls a try
EAW delivered in two days , no issues with the install and they have transformed the bike ticks over and runs sweet and i saved £100.00 on a pair
The wassell Build quality is as good as the premier anodised slide and removable pilot jet and significantly cheaper
in my opinion Amal need to improve customer service / stock availability or loose out the premier does not warrant the extra £50.00 per carburettor
and if you cannot supply quickly you are shooting yourself in the foot
