Needle ID please 36 bst's

[Antman]

Hi all

Removed these needles from my 36bst's  or 88 j carbs.

Stamp says 5F93 they have an even taper all the way through.

Much different to the factory ones which appear to taper again at least 10mm from the end.

Anyone have these needles or know what they are from.

Dyno jet??

Cheers

a pic would help but by your description and the fact the first 2 digits are 5F i would say they were Mikuni jet needles.

Dyno jets tend to have a radical step down taper and STD jets tend to be more gradual taper.

This is a dynojet stage 3 needle,

Hope it helps.
