I had tried acetone on my car without any real increase in either performance or economy, but wanted to see if it would make any difference on my HT 80.
Proponents of acetone recommend 3-4 ounces per 10 gallons of gasoline. For the 1/2 gallon tank on my bike this works out to about .2 ounces.
I got the engine running on the fuel that was already in the float bowl, got it cruising about 15 MPH. It had the familiar 4 cycling sound.
When the acetone mix reached the carburetor, there was a noticeable difference in sound with it 2 cycling in spurts a few times with an accompanying feel of acceleration. Then it settled to 2 cycling at a somewhat greater speed. I took it to town and around town. It was much smoother for the entire tank of gas, with easier starts. (my engine is not great on starting). Cold starting on successive days was also encouraging.
I know from working with cars that what works on one may not work on another seemingly identical engine. Also, I am NOT recommending acetone since I do not yet know the long term affects on plastic, fuel line items, and gaskets. I have two spare carbs so I am not taking any great chances trying this. Besides, .2 ounces per tank does not seem like a great amount of dilution.
As I learn more I will update it here.
