TKS FOR THE WELCOME!! I live north of Toronto in the town of Uxbridge but spend 6 months in Florida, not big on snow since I retired. I have many friends throughout the US. I buy most my parts when I'm in Florida, Canada is not a great place to buy stuff. Yes, the Yamaha had problems in the first two years but were resolved in the last year 1974. Luckily I have a spare engine, both are the fully updated type. My plan is to do a non-concours restoration but it will be done well. I will go over bore on the engine to 450cc unless the cylinders and piston are reasonable, which I doubt...
