Model-Year & Chassis Generation Notes
Built from 2007 to 2017, chassis SA37J/SA54J houses Yamaha’s own liquid-cooled 3-valve FI 49cc engine, whereas 2018+ AY02 Vino models switched to a Honda-built eSP platform.
Oil & Clutch Mechanical Engineering Note
Because a 49cc 3-valve engine spends most urban miles near wide-open throttle on just 0.78 L of SAE 10W-40 JASO MB oil, change the oil every 1,500–2,000 km without fail.
Garage Wrenching Gotchas
- Inspect drained oil for milky coolant emulsion on every service—aging mechanical water-pump seals on the 3P3 49cc engine are a classic wear point.
- Carbon buildup on the tiny intake/exhaust valve seats can cause low compression and cold stalling; use PEA fuel system cleaner periodically to prevent carbon-lock.
5. Frequently Asked Questions (FAQ)
What are the engine oil and rear hub gear oil capacities for the Yamaha Vino 50 Deluxe (SA37J 4T FI) scooter?
With an isolated dry CVT belt case, the engine requires 0.78 L drain-only or 0.78 L (0.82 US qt) with filter/screen (B65-E3411-00 (Oil Strainer Screen)) of SAE 10W-40 (JASO MB). Service the rear reduction hub separately (final drive 100 ml).
How do you accurately check the oil level on the Vino 50 Deluxe (SA37J 4T FI), and what are its service intervals?
Hold the bike upright on level ground 2–3 minutes after shutdown, wipe the dipstick, and rest it on the filler threads without screwing it in (threading it in reads artificially high and risks oil starvation). Torque the drain plug to 20 N·m with a new crush washer. Factory oil change intervals are every 4,000 km, with valve clearance inspection every 12,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the Vino 50 Deluxe (SA37J 4T FI)?
Fitted with 90/90-10 41J front and 90/90-10 41J rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 22 / 25 PSI (150/175 kPa) solo or 22 / 25 PSI loaded. Seat height is 715 mm (28.1 in) at 80 kg wet weight, delivering ~248 km per 4.5 L tank.
