Hi to anyone who has information about the Zipper Big Bore Kit for the 912S Rotax engine. I am interested in increasing the HP of my 912S but when I tap on the Zipper website a message pops up saying "There has been a critical error on this website". I am wondering if this means Zipper no longer sell/support this Kit for the Rotax 912S ??. Can anyone shed any light on this please ?. Thanks in advance. Regards, Allen B.
