Modern Buddy

Would this be the kit to do the upgrade? https://www.scooterworks.com/NCY-Cylind ... P8850.aspx
or any of the similar (if not identical) kits offered on eBay?

Since the Scooterworks kit is a Prima product and there is or was a relationship between Prima and Genuine, I'm thinking that if the Prima upgrade were done by a Genuine dealer, the warranty would stay intact. True?

That's the one I used for my BBK mod. But that's not a Prima its an NCY kit. So even if your dealer did the work, it would still void the warranty.
Its a good upgrade, if you do get it, have an autobody shop paint the jug, or it will rust and look like crap.

The local Genuine dealer told me he will only install Malossi kits. He has never had much success with other brands. Definitely voids your 2 year warranty.
