2.2 RUNNING IN
Running-in is important to allow the rotating parts, sliding surfaces and assembled areas to combine, as well as to allow the driver to
become familiar with the vehicle. During this period it is recommended:
– refuelling with 3% oil/petrol mixture;
– use oil mixture recommended in the section “RECOMMENDED LUBRICANTS AND FLUIDS”;
– heat the engine well before using the vehicle;
– drive for approximately 20 minutes with the throttle opened to 1/2 or less;
– make a pit stop and check assembled areas for slack, oil leaks or other problems;
– drive for approximately 40 minutes with the throttle opened to 3/4 or less;
– make another pit stop and thoroughly check assembled areas for slack, oil leaks, or other problems. Thorough checks and
adjustments are particularly necessary for cable routing, brake clearance, drive chain, spoke loosening and so on.
Repeat the procedures described each time they are replaced: piston, piston rings, cylinder, crankshaft bearings.
After the first 3 hours or 15 litres of fuel, replace the transmission oil.
