What's wrong?
The fuel sensor on the 2023 Harley-Davidson X350RA sits at the bottom of the fuel tank and reads the fuel level for the motorcycle. It also has to seal the opening where the sensor mounts to the tank. That seal matters because the tank holds gasoline directly above the sensor connection.
Harley-Davidson traced this recall to an inadequate seal between the fuel sensor and the bottom of the tank. When that seal does not hold as designed, gasoline can weep around the sensor instead of staying inside the tank. The repair kit includes a new gasket for the fuel sensor, which is the sealing piece that closes that joint.
Before the leak is obvious, an owner can see staining on the underside of the tank or debris collecting where fuel has wept. If you notice those marks, treat them as a warning sign and have a Harley-Davidson dealer inspect the motorcycle.

What's the safety risk?
A fuel leak near an ignition source increases the risk of a fire. Fuel staining or debris buildup on the underside of the tank is a warning sign of fuel weeping, so stop riding if you see it and contact the dealer. Repair is free at any franchised Harley-Davidson dealer.
What should I do?
- Check your VIN to confirm your 2023 Harley-Davidson X350RA is included in this recall.
- Contact a franchised Harley-Davidson dealer to schedule the free fuel-sensor-gasket replacement that addresses the fuel leak at the sensor.
- Bring the owner notice if you received one. Reference recall number 23V666 when you call.
- Avoid riding if you smell fuel or see fuel near the motorcycle. Keep it away from ignition sources until the repair is complete.
What happens at the repair
At the dealer, a Harley-Davidson technician replaces the fuel sensor gasket covered by the recall. The replacement parts and labor are free under the recall. Out-of-pocket repairs tied to a product failure before the recall notice are handled through Harley-Davidson's limited warranty, not through a separate reimbursement program, because the affected motorcycles are dealer-owned Riding Academy bikes. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
