Fired my 73 for the first time since October, petcocks on, full choke, 3 kicks, vroom vroom.
Doesn't hurt to sniff the oil for gas contamination and level, check tire pressure, the usual walk around. Hit, the swingarm zirks. check lever and brake fluid level. Check clean lube if needed, air filters. Battery electrolyte full battery charged. Check steering bearings for play. check chain tension. look for tight spots.
