Waking the bike up: the spring start-up checklist

Before the first ride of spring, check seven things: battery voltage, tyre pressures, brake feel, fuel state, chain, lights, and the floor under the bike — then treat the first ten minutes on the road as part of the inspection. Budget half an hour in the garage. Most of what winter breaks announces itself in the first kilometre, and the point of the checklist is to hear it in the garage instead.

Before you press the starter

Battery first, with a multimeter: a rested reading of 12.7 V or higher is ready to work; 12.4 V or lower means charge it before you crank. Spinning a cold engine on thick oil is the hardest job a bike battery does all year, and doing it half-charged is how spring no-starts happen. If the bike will not fire once the battery is known good, stop cranking and work the no-start checklist in order instead of flattening it.

Next, look for winter lodgers. Rodents nest in airboxes, exhausts and under seats, and they chew wiring insulation. Check the airbox inlet, look into the silencer, lift the seat, and follow any loom that looks disturbed.

Then fuel. If the bike was stored full and stabilised, it is fine — start it and move on. Untreated fuel that has sat for four or five months is the gamble: it degrades toward varnish, and carburettor float bowls hold the small, fast-spoiling volume that gums jets. If the fuel smells of solvent rather than petrol, drain the bowls, and dilute the tank with fresh fuel before asking the engine to run on it.

The checklist, in ride order

Check	What you are looking for	Ready when
Battery	rested voltage	12.7 V or higher
Tyres	pressure loss, cracks, flat spots	at placard pressure, checked cold
Brakes	lever and pedal feel, pad thickness	firm, no creep toward the bar
Fuel	age, smell, leaks at lines and cap	fresh or stabilised, dry connections
Chain	surface rust, kinked links, slack	lubed, moving freely, correct slack
Lights and horn	every function, both brake light switches	all working
Floor	fresh drips of oil, coolant, fuel or fork oil	dry overnight

Two of these deserve more than a glance. Tyres lose roughly 0.1 bar (1.5 psi) a month sitting still, so a bike parked in November is well down by March — set them cold to the placard figures, and use the pressure guide if the placard is missing. Brakes: a film of surface rust on the discs is normal after storage and wipes off in the first few stops, but a lever that feels spongy or creeps is not a storage symptom — that is air or old fluid, and it gets fixed before the bike moves.

First start

Turn the fuel on if there is a petcock, let the pump prime if there is not, and start the engine without touching the throttle. Let it idle. The oil light should go out within a couple of seconds; the idle should settle as the engine warms. A brief puff of white vapour at first start is condensation burning off and means nothing. Smoke that persists past warm-up means something, and it is worth identifying before the first ride rather than after.

No throttle blips on a cold engine. Cold oil is slow reaching the top end, and the first minute of a spring start is the worst possible time to spin it hard.

The first ten minutes

Roll out slowly and brake firmly twice at walking pace before you join the road — that clears the disc rust and confirms the bite point. Keep the revs modest until the engine is fully warm, and keep your inputs gentle: spring tarmac is cold and dusty, and tyres that sat all winter have hardened slightly and need time to reach temperature.

Mostly, listen. You know how this bike sounded in autumn. A new tick, a whir that tracks wheel speed, a clunk over bumps — anything that changed over winter is worth chasing while it is small. The first ride is a diagnostic session that happens to be enjoyable.

Close the loop

Back in the garage, log the wake-up: date, odometer, pressures set, anything found. That entry in the maintenance log is the season's starting point, and it makes the next services predictable instead of guesswork. If the wake-up list came up long — corroded terminals, gummed fuel, cracked tyres — the real fix is next autumn: better storage prep shrinks this checklist to almost nothing. From here, the habit that carries the season is the two-minute pre-ride check.
