To put your bike back into service after extended storage:
*Clean fuel system (tank, lines, all
filter screens, taps and carb
*Clean points and plugs with contact cleaner.
*Lube all grease fittings, advance unit, and chain, and cables.
*Change oil in engine, oiltank, forks, gearbox, primary chaincase. It is a good idea to unscrew and clean the sump filter and the oiltank filters, and then pour a half cup of engine oil in the rocker caps to drip down and lube tappets, cams and prime oilpump.
*Unscrew oil pressure light switch fitting, and force oil under pressure into the hole to prime crankshaft shell bearings.
*Kick over with plugs out until oil begins circulating.
*Check and adjust primary and rear chain tension, valve clearance, points gap and timing. It is not a bad idea to retorque head and cylinder first.
*Check tyre pressure.
*Replace battery, and fully bench charge new one before use.
*Strobe check timing, adjust carbs and cables, and test run during daylight hours, then check over for loose hardware.
