my friend has wrongly fill in a 2t oil in my 4t motorcycle engine stroke&fuel tank!now my bike engine stall half way thru&i can't start my honda ANF125?please help what should i do,without sending the bike to a mechanic?

Buy a new gas tank, unless the wrong gas has already flowed through the engine of the motorcycle. I wouldnt recommend doing this at home unless your a certified mechanic. You could probably ask Honda if the mechanics cant fix it. Good luck, blame your freind, make him pay the fees, take him to cour - im just kidding.

Turn off fuel petcock take the gas tank off. Empty it! Put about a quarter tank of gas in it and slosh it around...All around!Remove and replace spark plug. Fill With High octane gasoline. Put choke on and try to start it. This should work but get about 3 sparkplugs because any oil left in the system may foul one or two of them.
