💡 RECOMMENDED FOR GD OWNERS:
Single-cylinder engines vibrate more than twins—don’t risk a standard bolt vibrating loose. Upgrade to our Magnetic Sump Bolt for extra safety and to catch internal wear particles. View it here.

🔧 Service Tips for Singles

Flow is Key: Always warm the engine slightly before draining. This ensures the oil carries more contaminants out with it.
Fresh Seals Only: This kit does not include the rubber O-ring. Re-using a flattened O-ring is the #1 cause of sump leaks.
Torque Carefully: The engine casing is alloy; use a torque wrench to avoid stripping the threads in the block.
