  • Page 2: Engine Mounting

    To the engine worked properly and its properties have been optimized, the engine must be at operating temperature. Never adjust a cold engine. The carburetors are factory-set (in ROTOmotor). We do not recommend any dismounting of the intake manifolds, carburetors or connecting rods of the carburetors. The carburetors are on some types of ROTO engines mechanically connected and adjusted.

    Exhaust The elbows of the exhaust can rotate. As soon as the desired position is achieved, the center 19 mm bolt can be tightened to fix them in place. Warning! Do not damage the exhaust elbows ends! The extension pieces that can be attached to them might not seal properly.
  • Page 4: Engine Lubrication

    Use petrol 95 - 98 okt. + Motul 800 oil at 1:40. When using another brand or oil tip, warranty conditions are lost! You can order this oil at the e-shop on our website www.rotomotor.cz. Valve Adjustment In order to achieve long lasting engine performance, the valve clearance needs to be checked and adjusted if necessary after 2-3 hours of operation.
