A while ago I picked some rather tasty finned covers up from The Greensand Foundry. Look good on the XS.

They’ve been busy lately. Alongside single carb manifolds they’ve extended their catalogue.

XS650: Finned Covers   2 comments

I treated myself to some bling. Bike bling. Bright, shiny and finned. For the generator cover insert, points cover and atu cover. They kind of but not quite match the finned cover I already had for the push side oil filter.

There is a major difference aside from the fin size and density. The oil filter cover is milled from a billet whereas the others are cast. The bloke calls himself The Greensand Foundry Engineering and Fabrications. Hails from the Emerald Isles.

The technique is as old as the hills. Green sand casting. Burt Munroe used similar techniques to build the pistons etc for his record breaking Indian. Backyard engineering at its best. There is a wealth of information on this if youre interested. At your fingertips. Literally. Search engine of your choice. Just remember it gets hot. There are noxious gases. Metal shrinks as it cools. And you must be able to remove your pattern without destroying your mould.

A set of tappet covers to match would be nice.

Newly added to the range … you provide a good case …

XS650: VAM   Leave a comment

Back in the 80’s VAM was one of the leading french sidecross tuners. Produced some cool trick gear. Original 750, 880, 1000cc big bore kits. RHS engine case complete with fittings for remote oil filter. Possibility for rh pull clutch. Access for clutch without removing whole cover. LH generator case. Tappet covers……

Fred, from France has obtained the original castings I believe. Intends a production run. Needs a minimum of 10 pieces. When? No idea.

I would be interested in playing with a RH clutch case. If you want more info I have a phone number and an email address. Fred speaks French. Have no idea if he speaks English or German.
