Ok u guys and ur blow torches are crazy, Why dont we just through our mufflers of cliffs ey????? Anyone out there got dishwashers??? Probaly yes! Well we all know how to work one,, ya know put the soap in. Butt, Instead of soap you use ARMOR ALL CAR WASH CONCENTRATE. it is a blue substance. Pick it up at meijers or target or auto stores. Do not put anything in the washer with the mufler. Put it through 2 Dishwashing cycles. Each time put only a small amount (about 2/3 you would normaly put in with dishes) of that armor all car wash. After the Second cycle take it out immediatly! Blow drie it from one side, (or if you have a larger muffler on your moped like my kymco cobra's.) you can also roll up som napkins and put them in there and pull them out to speed it up.
This will work ive done it before. Email me or post your coments or questions
