Hi, yeah i have got the 1984 WP 4681 manual, but what would really be good is anything covering the old 3612 piggy back and remote reservoir twin shocks and the even older NV shocks back to about 1977, but until then i will have to make do with the latest 3612 BAVP manual from KTM. I spent hours and hours searching the internet in different languages for WP info but i think i have found pretty much every thing. WP is a bit different to Ohlins, i have got heaps of old Ohlins info, but finding the same for WP is not so easy. It looks like Richard will be able to help me with some stuff so thanks guys.
