Nice little package allows you to upgrade to a 4 petal reed valve. Fits on Peugeot or Puch Polini kits. The bolt pattern is stock Peugeot/Tomos a35 style so really, you can get crafty and fix this onto a lot of things. Of course, frame clearance and carburetor angle should be considered.
Comes with two intakes, a couple rubber gaskets, and all the hardware you should need.
