Hi: Ignition parts and the like are seemingly readily available on Ebay. So far I can either find NOS, brand new sitting on someones shelf for years, or used. Nonetheless, I find what I need. Don´t waste your time premixing, just let the bike do it´s thing and inject the oil for you. Just remember to watch your oil level about every 3rd tank full. Lastly, yes they smoke, that´s what makes them cool!
