What needle...

Re: What needle...

Re: What needle...

uhh, prob 9 needle, 50 idle and 92 main.

Re: What needle...

probably? anyone know for sure?

Re: What needle...

look it should be stamped on the jets / needle

Re: What needle...

mine came with a W7 needle and a 60 pilot. apparently it varies from carb to carb.

Re: What needle...

it does vary from carb to carb from the factory. I do not know why.

Re: What needle...

1 of mine came with a 92 main. the other a 90. both came with a w7 needle and a 60 pilot.

Re: What needle...

thanks. That was the needle I wanted. Just curious on the jets so I know what to order to tune.

Re: What needle...

The PHBGs are used on everything from Mopeds, Dirtbikes, Go Karts, Ski-Doo's.

All of those sorts of things. I imagine a distributer/factory trying to find the right jets for a East Coast e50, Metra 80 Small Bore, with a Simonini. Is much less cost effective than Shipping MetraKit a crate full of carbs that are jetted right for the MX50 Dirt Bike.

This is why we get Carbs with non sensical jetting.
