I finally got my scooter running today, but alas, no headlight due to bad wires coming from the gearshift side switch! They were all squeezed and torn under the cover.

Anyways.

I got a prima lefty but I'm not sure what jets I should be getting for it.

I have the stock air box, stock filter, no intake boot (yet, on it's way from india), and I am missing a few misc air box seals.

In the future I am going to customize the airbox and just put a K&N pod filter on the inlet, but for now I have the stock setup.

Any recommendations for good jetting baselines?

Stock Stella is in the low 100s IIRC. That's plenty for the big expansion pipe and a little extra for the air filter.

When I put a PM tuning on mine I had to change the idle jet also.
