I agree.
Keep in mind that you would need a special cylinder head. Also I think it uses a kaw 750 manifold and reeds cages.

I think it might be 550 only because where i work my boss bought out Mostly all of PJS's Molds and inventory and I've seen many of those around upstairs in our parts storage.
Go ahead and give the office a call between 9-6 the owners name is Gordon hes cool just ask him about it and he will let you know. and im %98 sure we have a couple of those heads for those cylinders.
Its Pacific Jet Sports
the number is (714) 671-1145
i wont be back working there until the weekends in a few weeks when wrestling season ends.

I agree that these are for a 650.. the pistons are much bigger than a 550 and as a result must be spread wider apart. The pistons would be almost touching if it was going on a 550 crank.. actually i have one of these at the house and it wont fit after looking at it.. it is not the same as 550 bolt pattern and the distance between the cylinder holes is way to wide for a 500.

Actually PJS made a 700 cylinder to fit the 550 sx cases,it required case boring to work but I remember seeing them before,the kit had the head,cylinder,pistons and everything with it.The sx cases do have a wider bolt pattern but not much wider.That particular cylinder is for the 650 engine though.
