Can anyone tell me what I would have to do to bring my 2002 800 up to 2003 specs? *I believe that among other things is, a new 12 petal reed cage, reed cage spacer, heavier base gasket and shaved head. *Any more???

I called ski-doo last spring when the 800h.o. came out and asked about converting my 800. *I don't remember what all had to be changed or upgraded. *Basically all they told me is it would be much cheaper buying a new sled with the h.o. than trying to build one.
