Yeah, if you can get the kit for the FR651V from psep, that would be great.
I know when I rebuilt my FR651V (died an early death because of overheating because it was assembled wrong), I did a bunch of googling and managed to find a Kawasaki gasket kit for it (don't have the p/n now, don't recall how I found it), but it was less than 1/2 the price of what all the local dealers said I should do, which was to go through the parts diagrams and buy every gasket and seal separately, as they couldn't guarantee the kit would have everything for my engine. It did, they knew it, they just wanted the extra money... :-( Some refused to even order the kit.
Now I order the majority of my parts out of the US (typically jackssmallengines), sometimes from partsbay.ca (sometimes their prices comparable [taking into account the exchange rate] and free shipping).
