Anyone used jets from these or are they cheap rubbish ? There was an article in scootering about them but cant remember if they were ok or not regarding accuracy ...cheers

I've used them in PHBH, SH and SI carbs and they seem to be very good.

I've no way to physically gauge the accuracy though.

After seeing this and having many KMT jets myself I ordered a few sizes from eurocarb (dellorto genuine) myself as well as an expensive needle gauge for these jets (PHBH main jet type).

I have only measured a couple of jets so far but interestingly both KMT and Dellorto originals seem to be too big for their marked sizes, by around 3 or 4, i.e. a 105 jet is actually 108+ on the gauge.

I'll do some more extensive testing ( I have every main jet from the low 90's to around 125 in KMT kits and a half dozen dellorto ones from the same range) when I get time and report back!

It's anew tool for me, so it might be something I'm doing, but we shall see!
