MOPED ARMY

Depends on what kit you match it too and what kit you are replacing it with. Airsal and Kstar might be close, Polini and metras look like they have much bigger ports.

so if you match for a polini, and end up getting a treats reed kit down the road then you're screwed?

Thats pretty much what I would think, I never had a puch Polini but my guess is the ports are a good deal bigger then the Kstar ones. On the other hand I dont think there would be a huge problem as long as you can still get the bottom gasket to seal up. My worry would be a kit with smaller ports not being able to "cover" the larger ported case and leaking.

I say 70cc reed valve kit.

But I am biased I have the Tomos Alukit which is the same but 1mm smaller making it a 64cc that I strapped on my Newport II and it rips pretty hard with a Homoet 4p and a bored out Bing. I run 18x36 and it takes me to 52mph. I don't have a four petal on there, yet.

I wish I would have waited a month to get the true 70cc Puch Treats kit. I wouldn't have had to modify the exhaust and it would have been a little more powerful. The hardest part is the intake. I made mine but... not everyone can do that, so it ads to the cost.

The Polini would be good too. Though, the ports are larger. I matched my Alukit and it is not too much bigger then stock and I would reckon that its comparable to the k-star. BUT the Polini is bad ass, so.....
