hey, nice to see another Brisbaneite on here. Let me know how you go as I'm as interested as you are.
In case you hadn't already seen the other threads, the only other supplier of NSR bits in Aus seem to be in Melbourne - ie "NSR imports" (no I don't have a contact, but the CMS guys can hook you up - believe it or not, they have a reasonable idea about the nsr - but nothing compared to the knowledge on here- as the owner of the place just fixed one up for himself). There's Also BC-components (a tyga reseller) and southerncross who has a fair number of basic second hand spares.
