FZ1 Oil Change

This is a simple service but also easy to mess up.  There is an excellent write-up on Pat's Motorcycle Page.

Tools Required

• 17mm socket
• oil filter socket
• oil funnel
• drain pan
• aluminum foil
• nitrile gloves

Supplies

• 3.1qt Yamalube 20-40 or equivalent*
• oil filter:  Emgo 10-22222, 10-22232, 10-22230, or equivalent
• crush washer, Yamaha part #214-11198-01
• rags
• cardboard

Procedure

This is easier to do with the bike on the center stand but it does not have to be.

Warm up engine for about 10 minutes.  Turn off, then loosen or remove oil filler cap.

Remove drain bolt on opposite side of motor with 17mm socket and allow oil to drain.

It is helpful to put the bike on its side stand to drain out the last bit of dirty oil from the oil pan.

Place aluminum foil on exhaust headers to prevent oil from contact with hot exhaust pipes.  Remove oil filter using oil filter socket.  Ensure oil filter gasket is attached to filter, not the motor.

Place a new crush washer on the drain plug, flat side toward motor.  Crush washer direction is important.

Bolt in the drain plug.  Manual says torque to 31 ft/lbs.  I just do finger tight + 1/8 - 1/4 turn.  This does not need to be tight, the crush washer will seal at low torque.  The risk of damaging threads is much greater and more difficult to repair than the risk of losing a little oil.  The plug will not fall out.

Put clean oil on the new filter gasket, then bolt on the filter.  Manual says 12 ft/lbs. but again finger tight + 1/4 turn is plenty.  Do not over tighten.

Chrome

Refill with 3.1 quarts of appropriate engine oil.  Do not overfill.  I mark the bottle so I know when to stop pouring.

After filling with the appropriate amount, run the engine for 5 minutes.  The manual says to let the engine cool for a few minutes and check the level with the bike on the center stand.  In practice I've found the oil level continues to rise in the glass for an hour or more and will read low if checked too soon.  Do not overfill, wait at least an hour before checking.

Oil at correct level

That's it!

* Note:  Yamaha no longer sells Yamalube 20-40.  From browsing the FZ1 list my understanding is they now recommend Yamalube 20-50 or equivalent non-synthetic oil, however many FZ1 owners switch their bikes to full synthetic.
