so some quick history while the photos upload to a hosting site. I bought a new 1974 commando in 75. in 76 i did the conversion to the dunstall body kit and mufflers, put 10k mi's on it and traded it of 1978 for a reliable bike... every electrical piece failed, the chain was done in by 10k mi and the camshaft also ate itself. i rode suzuki for years but could never get the sound clip out of my mind.. those dunstall pipes had a siren song all their own. i finally broke down and went hunting to buy back my 850dunstall. current owner was not every going to sell.... so the next best thing was to find another 850. In 2015 i was fortunate to locate a 73 in Ontario in pieces. the PO had pulled the head, new Kibblewhite valves, bronze guides and mushroom adjusters were already installed. the barrel had been bored to fit a new set of pistons and then it sat for 15 yrs. i paid a fair price and the PO crated it up and shipped out to the wild west.
