Hi Tim,
Yes, the Amals are going on to replace a tin full of corroded Amal bits, and no I haven't/don't work for TTS. I am a little unusual in that I have owned the bike since the late 70's, and I gave it the cafe-racer with a modified semi-race engine in the mid eighties, and TTS did the gas flowing work on the cylinder head along with boring to 460cc, they also balanced the bottom end and supplied the yoshimura pistons and 1/2 race cam.
I was impressed with their workmanship and friendliness at the time, although I think they are a much bigger concern now.
I only stripped the engine because along with the bike, it had been stored in a damp outhouse for20+ years, any thing chrome had gone, along with oxydising alloy
