Amal Premier Jet sizes

Hi all

I have received and installed my new 32mm Amal Premiers and they are terrific!

I had RGM set them up for a standard 850 sea level jetting and bolted them on and am good to go.

I did not bother to take out and write down what jet sizes are installed, are considered standard for 850

anyone tell me what size main and needle jets?

also, I was shipped a couple of 210 main jets and two 105 needle jets as I stated I was at 6000 feet alititude
and wanted one size leaner jets as extras to play with

Mains could be 220-230-260? Standard 850 needle jet is 106. Slides 3.1/2.

In that case, one size richer would be 220 & 106.

yes, that is what I suspect is installed now

thanks, LAB

I've had some success directly asking RGM and other vendors about bought items details.

Nothing better than carbs from the motherland! Especially shiny ones!

ya, that 1u3d got a nice bike alright!! lots of shine on the whole thing; braided fuel lines!!! braided oil lines too! but WTF? are those NGK plug caps???!! bet the bike runs quiet though huh?

I will have to buy a pair of those plug caps. They are now using noise meters at race meetings.
