Yamaha FZ1 1st Gen (2001-2005, carburettor) Maintenance Schedule and Service Intervals

Blue 2003 Yamaha FZ1

This is the maintenance schedule and associated service intervals for the Yamaha FZ1 1st gen made between 2001 and 2005, based on a carburettor-fed Yamaha R1 engine.

The first generation Yamaha FZ1 was also known as the FZ-S1000 Fazer in Europe, and is sometimes just called the “Fazer”.

It’s powered by a 998cc four-cylinder engine with DOHC and five valves per cylinder, a rarity in the inline four world. Yamaha later updated their R1 to four valves per cylinder, but the FZ1 remained a five-valve engine until being replaced by the Yamaha MT-10.

Yamaha didn’t update the first-generation FZ1 other than introducing the FZ-S1000S in 2005, with a black engine.

From 2006, Yamaha updated the second gen FZ1 with a 20-valve fuel-injected engine from a later R1.

Yamaha FZ1 1st Gen Maintenance Schedule

Below is the maintenance schedule for the Yamaha FZ1 1st Gen.

The schedule below is adapted from the manual and simplified, combined into one table for ease of reading.

Notes on the maintenance schedule:

  • At the end of the maintenance schedule, keep following it in the pattern shown.
  • The break-in service is omitted (that period has passed).
  • The km intervals are from the European manual. The intervals in that manual are wider than in the North American one, but they’re aligned in terms of order of magnitude.
  • Air filter: Later manuals recommend you don’t clean the air filter as you may damage it, and to replace it.
  • Hydraulic brake service: After disassembling the brake master cylinder and caliper, always change the fluid.
    • Regularly check the brake fluid level and fill the reservoirs as required
    • Every two years replace the internal components of the brake master cylinder and calipers, and change the brake fluid

About the Yamaha FZ1 1st Gen

The first generation Yamaha FZ1 was a very unique bike at the time, and remains an iconic shift in the way we understand naked versions of superbikes.

Its engine is based on the legendary Yamaha R1, but of course it is packaged in an upright chassis. This means it has a huge amount of horsepower (100+ kW or 140+ hp) and torque in a chassis that handles well and is comfortable enough to ride all day long.

The engine is the star of the show. It is a 998cc DOHC 20-valve liquid-cooled inline four-cylinder engine. Yamaha customised the cylinder head and intake ports for the FZ1, but otherwise a lot. ofit is straight out of the R1.

Fuelling for the FZ1 is out of four Mikuni BSR 37mm horizontally mounted carburettors, and a different airbox to the R1 as well. Even though this bike is carburettor fed, it has throttle position sensors so that ignition can be adjusted.

The engine is packed with tech to make sure it is punchy through the midrange as well as at the top end. It has ceramic composite cylinder bores (for better heat dissipation, resulting in more consistent power delivery), forged pistons, carburized connecting rods, and a lightweight clutch.

The Yamaha FZ1 also has an EXUP system (“Exhaust Ultimate Powervalve”) that adjusts exhaust flow depending on engine speed.

What makes the Yamaha FZ1 quite special is that it has very high-end running gear.

The suspension is fully adjustable at both ends. The front fork is a 43mm conventional (non-inverted) telescopic fork, and the rear is a link-type swingarm with a monoshock. Both units are made by SOQI, a Yamaha-owned suspension company.

On the front brakes, there are two 298mm discs with 4-piston monoblock calipers. The blue caps on the pistons remind you that they’re superbike spec.

So the Fazer is a powerful bike with great suspension components. It’s a lot heavier than its superbike companion, but it’s by no means slow and plodding. Thus, this isn’t a “standard” (despite being quite upright), as it’s too fast, but nor is it a “Streetfighter” (it’s too comfortable). Instead, the FZ1 blazes its own trail and is still a favourite — people have owned these early models for decades.

Manual for the Yamaha FZ1 1st Gen

The above information was gleaned from the owner’s manual for the Yamaha FZ1 1st Gen from 2005, but nothing substantive changed between then and the first year in 2001.
