XS650: Amal Single Carb   Leave a comment

Melv from Greensand Foundry has produced single carb manifolds for an Amal. Nice simple carbs.

Carb exiting to the left …

I made this manifold because I had lots of requests from people asking for a cast 2 into 1 that will fit in a standard frame loop. I made this to fit an Amal MK1 concentric, but will be making these to fit other carbs in the future. The Amal carb has a rubber o ring that seals against the machined face of the manifold!!!!!

Straight mounted carb …

He states: This is the first time I started the bike in 4 months. It usually starts first kick but the battery was flat!!!!! This is my straight mounted 1-2 manifold made to fit a standard XS CV carb. Internal bore diameter is 33.0mm. I made this because a number of people wanted it … personally I don’t like the standard XS carbs so adapted it to fit a trusty old Amal MK1 930 Concentric. My range of XS parts is listed on UK ebay!!!!!.

The jetting/settings on the twin Amal 930’s is   Main jet #140   Needle jet#106   Throttle valve (or slide) #3 1/2   throttle needle is 2 indent (which is the 2 small engraved lines above the clip grooves) and the clip position is second groove down or midway.

For the straight mounted 1-2 everything is the same apart from the main jet which is a #170.

See his other stuff here and here.

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.
