While adding oil to the gas at the Chevron station, for some reason I was unsure if my reservoir held enough Opti-2 for 3 quarts. Worst-case scenario, I'd have a burnt-up engine. So, after filling up, I pedalled home(across the street) and added more Opti-2. At worst, fuel/oil ratio would be 50:1 of Opti-2.....liveable for the Tanaka.
By the time I motored to work, the engine told me it was @ 50:1 ratio, not 100:1 like it should be. The engine was dying @ idle several times over the past few days. All I needed to do was readjust the carb to compensate for adding too much oil. The bike uses 12 ounces of fuel daily, so I'll fill up w/100:1 Opti-2, like it should be, in 8 days.
Better safe than sorry.
