Yup, that's about all I know about it also. I saw it for $800.00 but 900.00 is close enough for me.

They make pretty good cooling kit for the 500ex, I was reading on it..Costs lots of money I really don't think its worth it..why all the power when you can get a decent 440 kit.

Hey go to ebay and there is a guy selling a 500ex just type that in and you can read what all he did. He sent to a company called 4 stroke tech i think and got it all done. (ported and polished his heads too). Read it, it is a sweet quad.

Probably the reason you only get 8 hp is because that is just a bump up in CCs, not everything. If you had cam, filter, pipe, jet it, piston and whatever else it would be putting out some serious HP
