Thanks the kind of reliability im looking for :)

Ever have it dyno'd?
 
The 800 SRX was the same bottom end, the 74mm bores have thicker aluminum around them as well larger internal transfer castings, the outside looks the same.

What you have to do is bore the cases .125 larger for the wider sleeves and they drop right in. Wher ethey ran out of room was on the top, they have gaskets instead of orings.
