Adjustable power jet kit for Lambretta, Vespa and Gilera. Kit comes with all you need to convert your carb to power jet spec. Many owners are changing their carbs this way to assist with jetting.

The kit includes a drill bit and metric tap to enable you to drill the correct sized hole and cut the correct thread for the fittings.

Please state which size carb the kit is for.

Please note, the price is for DIY fit only. We highly recommend that you get the power jet set up on a dyno. There are scooter tuning shops with an excellent reputation, who will be able to do this for you.

If you do not feel confident enough to attempt this yourself, please contact for a quote to fit a kit to your carb. All you need do is then send us your carb for conversion.
