Reed valve

Hi Having now put a DR177 kit, 24mm Kelin carb, Sito+, racing crank etc on my VBB I'm now considering adding a reed valve set up.

The main reason is to stop the blow back of fuel but also the added benefit of more power.

I would rather not have to strip the engine again so my question is what complete set up is best for my Vespa?

Thanks, Sean.



You can not use reed valve w/o grinding of the rotary valve at the casing.



Best is the malossi reed kit here:


How to grind the casing you find a picture here:
