Yes I know dangers related to the use of acetone.
Everybody use at their own risk.
I had no problems on my veihicles but certainly it's not true for every vehicle.
Once a friend of mine found it very useful.
Soon in my country will be obligatory to do a gas checking during periodical bike checkings. After brake, lights and other equipement controls they have added gas control.
Quite every riders of Harleys have paid the so called "Harley Tax", change pipes, air filter and carb tuning to free the engine.
When the control comes exhaust emissions are out of range.
Adding acetone and using it for 2 days before and during controls permits to reduce exhaust emissions and maybe pass the exhaust check.
