Don't let the guys at Badmotorscooterparts talk you into buying the cheaper Airsal brand bore kit. They claim it's the same, but I would say that it's similar to the Polini kit. The casting looks similar dimentionally, but the difference is in the transfer and exhaust ports. The Polini ports are much cleaner and most of the casting flash has been removed from inside the ports. Also the port shape is diferent. Remember that you usually pay for what you get.
