Yamaha XV1600 Road Star (1670cc, carburettor, 2004-2007) Maintenance Schedule and Service Intervals
This is the maintenance schedule and associated service intervals for the Yamaha XV1600 Road Star motorcycle range. In Europe the XV1600 was known as the Wild Star.
The Yamaha XV1600 Road Star was released in a number of variants, including the Road Star Silverado and Road Star Midnight, which is (you guessed it) blacked out. They all have the same underlying engine — a bored-out 1670cc carburettor-fed V-twin engine — and thus all share the same maintenance schedule.
The 1670cc Yamaha Road Star replaced the earlier 1602cc Yamaha Road Star, and was replaced by the fuel-injected one of the same displacement in 2008 (the 2008 XV1700 Yamaha Road Star).

Yamaha XV1600 Road Star Service Intervals
Overall, the Yamaha XV1600 Road Star has 4000 mile or 6000 km service intervals between oil changes. At that point grease external points and check everything (see the service checklist below).
Other than that, the valve service on the Road Star is every 16000 miles (25000 km).
Every 2nd service, change the spark plugs, and every 4th service, repack the bearings and change the transfer case oil.
You’re supposed to check the belt tension every 2500 miles / 4000 km, as well, but modify that as suits your riding conditions.

Belt Tension Maintenance
To check the drive belt slack, you should follow the steps below.
- Put the motorcycle on a level surface and hold it upright.
- Check the marks near the drive belt check hole
- Note the current position of the drive belt. (The marks are 5mm / 0.2 in apart.).
- Using a belt tension gauge, apply upward force of 4.5 N / 10 lbf to the belt, and note the position of the belt with the force applied.
- Belt slack: Subtract the first measurement from the second one.
Target belt slack is 7.5-13mm (0.3-0.5 in).
To adjust belt tension, check your service manual.
About the Yamaha XV1600 Road Star
The Road Star is an iconic cruiser from Yamaha. It looks good, it goes well, and is very reliable.
The Yamaha XV1600 Road Star was first launched in 1999 with a carburettor-fed 1602cc engine.
This was updated in 2004 to be bored-out 1670cc engine. The displacement is the same as that of the Yamaha Warrior, but the tuning and some internals are different (though to be honest maintaining them both is very similar!)
Knowing that many riders are exceptionally aware of the livery their bikes come in, Yamaha added a Silverado variation to its Road Star line-up. The Silverado comes with bags and a windscreen.
The platform is identical, and the new machine relies on the same proven 1670 cc air-cooled v-twin with a 5-speed transmission and belt drive.
The engine, in base form, pulls a massive 99 ft-lb (134 Nm) at a low, low 2250 rpm. Peak power is 47 kW (63 hp) at 4000 rpm, but few people worry about peak power on cruisers until they hit drag strips.
Ride gear is pretty simple on the Road Star. It does have twin front disc brakes at 298mm in size, with two-piston calipers gripping them.
Manual for the Yamaha 1600 Road Star
The above information was gleaned from the owner’s manual for the Yamaha Road Star, and it’s the same for all other Road Star variants (e.g. Silverado).
The manual is consistent for all years between 2004-2007.
