live longer. The lter must be oiled well, with a good quality foam airlter
oil. Clean and re-oil or replace after each 5 tanks of fuel.

Running-in
The engine is brandnew and requires a run-in session. This run-in session will allow oil to lubricate the inner parts of the engine,
the piston and sleeve will get the best possible match and some coal will develop and create a perfect seal inside the engine. Fol-
low the section Engine run-in carefully. It will protect your engine and increase performance and lifetime.
