..............my own fault
! There was some cast letters on the cover, and it was painted, so I decided to remove the paint with a little heat, and grind off the letters.......anyway cut a long story short, the porosity of the die casting came through, so I had to skim it, and skim it, until there was nothing left to skim 

Looks like my old 125LC master cylinder, I recognise the diaphragm!
.................That aluminium swarf gets everywhere, and I mean everywhere
. At the time I was casually looking about and came across the small push buttons from China for £3/each, so ordered a few and forgot about them. I stumbled across them so set about making my own version. Not used a rotary table in anger for years so it was a good refresher and nice to get my hand back in. I'm chuffed the way they turned out, but in time and labour would cost about 3 x the price of the £80 ones 

nice work have you vacuumed up the mess yet
............took nearly as long as making them
CNC free zone in my shopWas this machining free hand or cnc?
The XS650 engine is often mentioned as a copy of the Norton & Triumph styling at the time..............I suppose the Japanese designers back in the 60/70's are akin to the Chinese bike designers nowadays...![]()
BSA owned a company in Japan called Meguro who built Bsa's under licence and bikes of their own. Meguro was taken over by Kawasaki and thats why they build the w650's and other British styled retro machines.

So how did you do the outside shape freehand? Beautiful BTW.CNC free zone in my shop![]()
A mate of mine had a yamaha 650 in the late 70s ...I borrowed it a few times, I almost bought it off him when he bought a Jota ...I really liked it ,it handled very nicely ....
