PBU race ported cylinder & boost ported piston

I was on the PBU website today and found that they have a race ported cylinder and boost ported piston and I am curious if anyone has installed these two products in their banshees and what kind of performance gain if any were noticed.

Thanks
Rick

I personally don't have any experience with that particular kit, but I do know that these kick arse.

New BiZeta (BZM) Upgrade kit for Polini engines

Sorry, didnt meman to jack the thread. But I have a few customers here (GABE) that has one and loves it.

I received my kit on friday and will say that it made a huge difference from low to high, highly recommend also i had previousely installed the reed blaster box with the Mikuni 20mm and have been woopin a*# ever since, very quick thottle and no lag. Ask to have their new carbon reeds installed, they should upgrade at no charge.

The BZM 50cc Cylinder/Piston kit is definately on the top of my list to replace the stock top end on my banshee but I would like to know what the PBU products has to offer.

the bzm head really trully kicks much but. I am 260 and just about laped everyone on the last race. I will find the video for you guys.

you will need the divix codex on your comp for it to work right
