Service Log is a dated maintenance diary for your karts. Every time you service something, log the job against the kart: pick the item, type the kart name, set the date and add an optional cost and note. The item list covers the jobs that come round every few meetings: chain, sprockets, clutch, brake pads, brake fluid, carburettor, wheel bearings, kingpins, seat and mounts, routine engine work and other.
Plenty of race-day failures come down to a part nobody could remember servicing. The Last done strip at the top answers that at a glance: one chip per item showing the most recent date it was done across all your karts, or "never" in amber for items with no record yet. You judge whether a date is too old; the strip puts every date in one place.
Below it, History lists every job with the item, kart, date, cost and note, with a count of jobs logged. That record helps when you sell a kart, hand it to a mechanic or try to work out why the clutch is slipping again. Job costs are added to the Running cost total, so maintenance spend is counted with everything else.
Full engine rebuilds belong in Engine Hours, which records their cost and resets the countdown. The Engine item here is for routine work such as the piston, rings, plug and exhaust, so the same rebuild is never counted twice. Entries are stored on your phone and the tool works with no signal.
