In another thread I posted several links to various writings by Robyn Landers as I was unable to find the main page for his v4 info. I finally found it and feel (as I hope the mods and others will) that it has tons of good info on the Early V4's particularly the vf models. This info is reasonably organized and all in one place. http://www.math.uwaterloo.ca/~rblander/moto_long.html I hope this will make or be added to gen1-2 links stickied in the sub forum. Many of the Gen X subs may already have this but it would be great if each gen had a sticky for links containing detailed info on each. Ultimately it would have to be split into one thread to suggest links and another for those that made the list.....Obviously this might require quite a bit of time to maintain. But I feel is needed at least for the older gens where certain info and/or parts may only be found in one or two places in the huge sea of the internet. Anyhow hopefully someone will find this info useful as the link above is the single most complete source of VF F cam and oiling info that I know of. It also includes links and sources with further info. Enjoy Db
