Here is the beginning of my review for the Puch Airsal EUROKIT 47mm 6 port kit.
When I first caught a glimpse of this cylinder a year or so ago, I knew there was going to be some fun had once it was made available. Thank you, Benji, for getting Airsal to make a special batch.
Going against my normal routine of cutting into the cylinder before ever running it, I will be leaving this one stock for a short period. Once i get some miles on it, off it will come for further tuning. I'll make sure and keep all of it documented here.
This kit is not for the beginner/grom/halfassers out there.
Transfers are GIANT and require the cases to be welded up
Here is a Gila with the Eurokit gasket scribe
Here is the smallest space on the Eurokit. Lots of extra room
Intake and exhaust
As you might have heard, you must play with the spacing to get the right piston-head clearance. In my findings, you will need to add around 1mm to get in the correct squish range. So grab some .50 and .75 gasket paper to cut your base from and buy an extra 47mm head gasket and you'll be all set.
This is tdc with no base gasket
Today was the first day running it. It is a total blast to ride and is unlike the feeling of a fast Gila or Polini. It has the classic, piston port kick in the pants torque, super high compression and is noisy as all hell. The out of the box performance is crazy and Airsal has designed this kit with tons of extra material for further tuning.

2 shoe with kick start springs

Bottom line is you NEED to build one. Puch Kit of 2013
