Reworked Cylinder

Hi I want to know what are the differences betwen de malossi cylinder kit for the Piaggio Skipper and the reworked for the SIP jointpipe one.Works the normal one on the SIP jointpipe?Are only perfomance increase?
Sorry but i dont know any deutch…and only a little bit english[:rolleyes:]

the reworked cylinder works with the sip jointpipe and your performance will increase, but you cant use the original jointpipe properly anymore. the other way arround the performance wont increase
