While many additives available may
reduce deposits, Yamaha recommends
the use of Ring Free Fuel Additive, avail-
able from your Yamaha dealer. Ring
Free has repeatedly proven its ability to
clean combustion deposits from inside
the engine, notably the critical piston-
ring-land area, and fuel system compo-
nents. Follow product labeling for use
instructions.
