Symptom: Hiccups/hesitates from dead stop, not all the time. Feels like gas is not going in.. like "pushing start"..
Did it act up before or after you added the Lucas fuel treatment? If it didn't act up until after you added the Lucas fuel treatment how much did you add? I don't believe using premium gas will help at all, your scooter is designed to run on regular gas.started last night on my way home.. intermittent.. I just put a Lucas fuel system cleaner/treatment and will use premium gas.. see if that'll do the trick.. 18700 on the bike.. K12
Run the whole tankful and be prepared to add the SeaFoam to a second tank also. It often works with a single tankful, but some deposits are more stubborn than others.
These posts seem to conflict with each other. I would agree with ChipDoc that it may take more than one tank to get the results you want. I don't see what using SeaFoam more than once every year or two would hurt. perhaps MarilynsPrince will enlighten us.A couple of tanks at the most once every year or two. Don't forget to check the fuel flow (filter) and air filter.
