I’ve noticed whilst searching for parts for my ZZ (a lot older I know, but bear with me) there is a lot more available in the US. Parts that, over here, you get a blank look from the man behind the counter when you ask for, are widely available over there.
I usually get bits through that infernal auction site, and if you do a bit of searching, some peoples shipping charges are very reasonable. I just got a new fuel bowl, all-in about £20 and it only took six days to arrive!
