This is the maintenance schedule and associated service intervals for the Yamaha XT350, a single-cylinder air-cooled carburettor-fed dual sport that was kick-start only (but also very light!). It was made from 1991 until 2000, staying the same in the whole period. But many are still in service today, because they’re bulletproof.
The XT350 is powered by a 346cc single-cylinder engine with a gentle compression ratio of 9.0:1. Its dry weight is a featherweight 120kg, which means its 23kW of power (31 hp) gets it really far — it’ll even do highway time, if you’re brave!
After its retirement, the Yamaha XT350 was effectively discontinued. These days, the equivalent is the more advanced Yamaha XT250.

What you need to service a Yamaha XT350
If you’re servicing a Yamaha XT350, you need to start with basic motorcycle maintenance tools.
After that, here are the basic consumables you need to service your XT350.
Your XT350 is a carburettor-fed, air-cooled motorcycle with a chain drive. It has a disc front brake, a drum rear brake, and… precious little else. Keep it lubed and hopefully it’ll go for a while (though not forever, some complain that the valves tend to fail after about 50K miles).
|Part||Yamaha XT350 Spec|
|Oil||The XT350 isn’t a demanding bike — use a basic oil like Yamalube 10W-40.|
|Oil filter||Hiflofiltro HF143 oil filter.|
|Spark plug||Use an NGK D8EA spark plug.|
|Air Filter||You need a Hiflofiltro HFF4019 foam air filter. Keep it maintained with Yamalube air filter oil|
|Chain||Maintain your chain with a Motul chain care kit or Motul chain paste|
|Grease||Keep external pivot points greased with lithium soap-based grease.|
|Brake fluid||Use Castrol DOT 4 or similar|
|Brake pads||Use EBC graphite brake pads, FA101X for the XT350.|
Yamaha XT350 Maintenance Schedule
Below is the maintenance schedule for the Yamaha XT350.
The original maintenance schedule for the Yamaha XT350 was broken into two sections: periodic maintenance for emission control systems, and general maintenance and lubrication. But these have been combined for simplicity
Yamaha recommends you get a mechanic or dealer to service everything other than the chain, oil, and major lubrication points. (Not likely!!)
- Beyond the end of the maintenance schedule, follow it in the pattern shown
- The break-in schedule is omitted as the XT350 is no longer sold new.
- The below maintenance schedule is for the US-delivered XT350. The European spec is a little different.

About the Yamaha XT350
The Yamaha XT350 is a lightweight dual-purpose bike that packs plenty of usable punch for both occasional road hauls and off-road exploration. It’s exceptionally maneuverable and ready to tackle rough terrain.
The XT350’s single-cylinder air-cooled 4-stroke engine provides a broad range of torque, making it reassuring in pretty much any scenario. You may not want to cross the country on high-speed freeways on it… but you could… in the slow lane!
Thanks to the precise steering that the short wheelbase provides and convenient 5-speed transmission, the Yamaha XT350 is easy to ride, especially with quickly-adjustable suspensions to offer the best damping and compression for all kinds of surfaces.
Many people have a special place in their heart for the XT350. Even decades after the last one was made, there are lots to be found in people’s garages — though relatively few on the used market. It’s one of those bikes that people either regret selling, or know they’ll regret selling.
What’s quite impressive is that you can actually push the XT350 to some serious speed — north of 120 km/h (75 mph) or even 140 mph (90 mph) if you’re patient. Of course, riding the XT350 isn’t about getting to top speed — but it’ll do it if you need it to.
