INTRODUCTION
Yamaha Motor Corporation, U.S.A. has decided that a defect that relates to motor vehicle safety exists in certain 2020 and 2021 model XVS95C (Bolt) motorcycles.
Due to irregularities in casting temperatures caused by the improper application of a mold-release agent during manufacturing of affected units, there is a possibility that the engine cases may be porous near the oil filter at the bottom of the engine. If there is porosity, oil could leak out onto the rear tire, increasing the risk of loss of control and a crash with injury or death.
To correct this defect, Yamaha is initiating a Factory Modification Campaign. Affected units must be inspected for oil leakage at the bottom of the engine according to instructions in this bulletin. If an oil leak is confirmed, contact your Motorsports Technical Advisor (MTA) using an Online Tech Request or a Live Chat on the Yamaha
Dealer System (YDS) to obtain a replacement engine.
Yamaha is notifying all registered owners of affected motorcycles by mail. A copy of our letter is included in this bulletin. The customer should take this letter along with the affected motorcycle to an authorized Yamaha
dealer for modification.
If your dealership was invoiced for one or more affected units, a computer report listing all affected motorcycles invoiced to your dealership is included with a mailed copy of this bulletin. Use the list to help ensure all motorcycles inspected and, if necessary, modified. All sold motorcycles that have been registered with Yamaha will show the customer’s name and address.
Your dealership must notify the owner of any affected motorcycle that was actually sold but listed as “unsold” in the report. You must inspect and, if necessary, modify all affected motorcycles in your inventory as well as all customer-owned motorcycles brought to you for this service. Any affected motorcycle that you purchase from Yamaha in the future may also require modification. If you purchase a motorcycle from another dealer or Yamaha
, check to see if the procedures in this bulletin have already been performed before you sell the motorcycle.
Motorcycles that are affected should not be operated until they are inspected and, if necessary, modified. It is a violation of Yamaha policy for your dealership to deliver any affected motorcycle to customers until the procedures in this bulletin are performed.
SERVICE PROCEDURES
WARNING
Be careful when working around the hot engine and exhaust while checking for leaks to avoid burns.
Sold Units
Check the area near the oil filter under the engine shown. An oil leak should be readily identifiable on a motorcycle that has been in operation.
TIP: If uncertain, degrease suspect area of crankcase prior to inspection for oil leak. After degreasing, clean around bolt with shop rags. It may be helpful to use an oil leak detection powder or an aerosol powdered deodorant to make any oil leak more visible. Run the engine as instructed for Unsold Units below.
Oil leak: Contact your MTA using an Online Tech Request or a Live Chat with photos of the oil leak. See Parts Information on page 4.
No oil leak: Submit a Recall Claim for the inspection procedure (see Warranty Information on page 5).
Unsold Units
Check the area under the engine around the bolt as shown above, using the following procedure:
1. Prepare the motorcycle for operation. As needed, add fuel to the fuel tank, install a fully charged battery, and check engine oil level.
2. Move the motorcycle to an area with adequate ventilation. Put a clean piece of cardboard under the engine. Set the cardboard just under the side stand to avoid sliding.
3. Set up a fan in front of the motorcycle.
NOTICE:
Unless a fan is used, the engine could overheat.
4. Use a tachometer or connect YDT to the unit to measure rpm.
5. Start the engine and hold the throttle open to run it at 5000 rpm for 3 minutes.
6. After running the engine for 3 minutes, turn off using the emergency stop switch and then turn the key off.
7. Inspect for oil leakage at the suspect area of the crankcase.
Oil leak: Contact your MTA using an Online Tech Request or Live Chat with photos of the oil leak. See Parts Information below.
No oil leak: Submit a Recall Claim for the inspection procedure (see Warranty Information on page 5).
8. If a new motorcycle does not have an oil leak and is going to be stored rather than prepared for the showroom or delivery, remove the fuel tank cap and drain the fuel from the fuel tank. Replace the fuel tank cap.
9. Turn on the key and check if the engine warning lamp turns on and then off. If the lamp stays on, then an error has occurred. Use YDT to determine and repair the error.
10. For a motorcycle that will be stored, turn the key off and remove the battery (wait for more than five seconds after turning off the key). Disconnect the battery carefully to avoid a short circuit.
PARTS INFORMATION
If the engine is leaking due to porosity in the crankcase, contact your MTA on YDS using an Online Tech Request or Live Chat with photos of the oil leak. When the oil leak due to porosity is confirmed, Yamaha will arrange to send you a new engine at no charge. Install the new engine when it is received according to the Service Manual.
