plastic riser for puch athena and honda MB5 4 petal reed modification. so you can use one of these and a gilardoni type reed block will fit in there. if you're using a
malossi VL6 reed or something like that you may have to take off the reed stopper thing on one side to make it fit. the
gilardoni block,
polini block,
doppler blocks and others need some dremeling to open up the mounting holes a bit.
this is for the athena AJH version ONLY. and works with all honda MB5 kits
Works but...
