Default Starting a full restoration on my 1967 Triumph T20SM Tiger Cub

I have a history with Triumph Motorcycles...A LOVE-HATE relationship. I had my first Triumph, a 1967 200CC Tiger cub when I was in High school in 1969. It was broke more than it ran.
Around 1971, I bought a 1967 Triumph 500, T100C which was a single carb, 500 twin with with the up-swept pipes. I rebuilt it and put a twin carb Daytona head on it and I was "Steve McQueen jr" in the dirt and street. I was 22 yrs old and bullet proof. I sold it a few years later. Roll ahead 18 years, 1992, and at 40, I buy this 1967 Tiger cub from a friend of mine with about 2700 miles on it. I enjoy it around town trails and such. I would take it to the beach areas of Los Angeles in my truck when I and my family would visit my parents. 2009 was the last year the Cub was registered and I parked it.
So now 66 yrs old and the clock ticking away on my motorcycle riding days left, I pulled it out, pulled the engine and today I got the engine most the way torn down. I have a roller crank pin to put in it, newer Amal Concentric carburetor, An "R" cam and I am sending the cases to a guy back east that will do some machining on the case to make it more "Oil Tight". He will build the crank for me as it consists of three pieces, right and left flywheel and crank pin. It needs to be pressed apart, new pin installed with the rod and then balanced and set up between centers and set up with two dial indicators. He will install high grade valve guides and bore the cylinder to fit a larger Japanese bike piston that seals better with good rings.

The FRAME, I will take completely apart after the engine is done and have it powder coated, the tank repainted, install a single Trials seat and alloy rims with Stainless steel spokes. So here is a picture of it as it sat before I took it apart. I will post as I build it. Wish me LUCK and PATIENCE because it is BRITISH!
