Has anyone ever used this product in their bike? I've used it in my cars and it did clean up the fuel system, also got a little better fuel mileage.
Just to be put in the fuel tank not in the motor oil in the bike.

I to have used it in every thing ,don't know for sure what good it does ,
But it always looks cool sitting on my shelf in the garage.

I've used it in the gas and oil of my bikes for years. Like the others, I can't say for sure that it does any good; but it's never done my bikes any harm. It makes me feel better enough that I keep buying it.

I've never had a slide or float to stick in a carb while using Marvel. During the winter I always store my bikes with Marvel in the gas tank. I think its probably prevented trouble, especially this past winter. I went 4 months without riding. My Savage fired right up and ran perfectly the first time I cranked her this spring.

I've also used it for years, using an upper cylinder lubricator.  MM Oil will not combust in the engine's cylinders. Whether you put it in a gas tank or an upper cylinder lubricator, in either case its vapor is drawn in past the intake valves, into the cylinder and pushed out through the exhaust valves, into the exhaust pipes.  Since it is an oil, it lubricates everything it comes in contact with.  Valve stems and seats, piston tops and cylinder walls all get lubricated from the vapor of this product.

I have a car who's compression ratio requires 91 octane gas, which is costly.  I wanted to use 87 octane. Problem is the combustion temps get too hot using 87, and pinging (pre-ignition/dieseling) occurs.  I solved the problem using MM oil and an upper cylinder lubricator.  The MM oil goes in the lubricator. It is connected via a hose, to a small, cheap transmission cooler radiator located in the airstream behind the front grille of the car. It then is connected via a hose to the intake manifold.  The MM oil is sucked by intake vacuum through the cooler into the combustion chamber.  Since it is cooled oil, it reduces the temp of the combustion in the cylinder, thus reducing the need for 91 octane gas. The car now runs on 87 without a problem.

I love the stuff...

but,... I miss the can...
Let's start a "Bring back the tin can" campaign.... ...

Large sized Upper Cylinder Lubricator to be used with Marvel Mystery Oil.  The advantage is that you can regulate the amount visually through direct injection from intake vacuum:

No. Its too big for a bike and even though they make smaller versions, you probably couldn't use it on the Savage.  The hose/tube that is used to allow the MM oil vapor to enter the cylinder, has to be fitted to an intake manifold or its adapter. That would mean precise fabrication of an adapter plate to be placed between the carburetor and the engine, and then you might encounter various other problems by doing that, like spacing issues.
