This is another one of those "repeating threads" where info on the subject can be found by doing a search on the site. I went as far as to post the MSDS for Marvel Mystery Oil. There was quite a lively discussion about this and other lubricants. You used to be able to add a port to your carb manifold to drip MMO into the intake from a remote reservoir for "top cylinder lubrication." That was one of the JC Whitney staples in the fueling section of their print catalog along w/flat "pizza-tin" air filters of differing sizes and anti-fouling extensions for spark plugs.

I use a couple ozs in my bike and gas tank all the time. I add it to everything I own, bike, boat, all my vehicles and even my plane. I often wandered why I never had rust problems in my Vmax like a few other members. I guess Dannmax may be right about the myth of MMO prevents rust in your fuel tank.

If you are using a good quality engine oil I can't see that you would get any benefits.

Mr Max is:
A 1999, 1300cc with Mikuni 40mm TDMR Carbs, gassflowed head, Holeshot headers with custom silencers.
It is kept off the ground by Dymags coupled with Racetech springs and emulators at the front and White Power shocks at the back.
It is slowed down with an ISR radial master cylinder and six pot callipers grabbing onto Braking wave discs.
