Yamaha Motorcycles (aka Star)
& ATVs

Need a place to obtain technical specifications you need to repair or service Yamaha motorcycles and ATVs? Can't find an old, out of print repair manual? You have found your free resource here.

Check the Need To Know pages if you are not familiar with older bike systems, carbs vs fuel injection or points and condensers instead of a more modern ignition system. You will have that classic Seca or XS running in no time.

FYI: Current Yamaha cruiser style models are marketed under the name Star Motorcycles. The Yamaha brand is limited to ATV, sportbike, dirt or off-road motorcycle, UTV and SxS (Side by Side) models.

Basic Yamaha Reference

Easy to use chart lists the most commonly searched for specifications. Includes spark plug and gap, bike weight, battery, engine oil capacity, recommended tire pressure and tire, front & rear sprocket and chain sizes.

Advanced Yamaha Reference

The same easy to use chart style containing more detailed information for more complex repairs or service jobs. You will find tightening torques, ignition type and resistance values, carburetor or fuel injection system info, stock jet sizes (carbs), fork oil height, ignition timing info and firing order.

Other Service Information

Where to access online fiche, service data, owner's manuals and Yamaha's Factory Modification Campaign list. For those of you who do not know, "Factory Modification Campaign" is just their way of saying Recall.

Yamaha Photos and more

  • Photos

  • Wiring diagrams and schematics.
  • Links to some additional information.

  • We will be adding more specs for Yamaha motorcycles, ATVs and dirt bikes as new model year information becomes available.

    If you find the type too small to read comfortably please use Ctrl+ to make the type larger. This means hold down the Control key (lower left on keyboard, says Ctrl) and press the + key (upper right, next to the backspace key, it has a + and = on it, or on your number keypad).

    Just a note: when referring to the "Big 4" Japanese manufacturers we will usually just use a capital letter. Example H for Honda, S for Suzuki, etc.
