This MOTO1988 fuel tank petcock is an aftermarket replacement built to match OEM fitment numbers 51023-1390, 51023-1148, 51023-0003 and 51023-0715.

How will this petcock fit my KLR650?

The MOTO1988 valve is engineered to match the original Kawasaki mounting geometry and flow ports for KLR650 variants (KL650 A1–A19 and later KL650E* editions). Before purchase, compare your stock petcock to the product image and OEM numbers listed to confirm compatibility. If your bike uses any of the OEM numbers included, the swap should be direct with no modification required.

• Compatible OEM part numbers: 51023-1390, 51023-1148, 51023-0003, 51023-0715.
• Fits KLR650 model years 1987–2018 (KL650 A1–A19 and KL650E series).

What comes in the package and what tools will I need?

The kit contains everything needed to install the petcock: one fuel valve assembly, one fuel filter, two lengths of fuel line and four clips to secure hose ends. Basic hand tools are normally sufficient for installation—generally pliers for clips, a screwdriver or small socket set for tank removal, and safety supplies for draining fuel.

• Included: fuel petcock valve ×1, filter ×1, fuel lines ×2, clips ×4.
• Typical tools: pliers, screwdrivers, small sockets, and a fuel-safe container.
• Installation time: most DIYers complete the swap in under an hour.

How does the three-position selector work and why it matters?

The valve provides three settings—On, Off and Reserve—so you control fuel flow and reserve capacity without altering fuel routing. On supplies fuel from the main pickup; Reserve uses the lower portion of the tank when fuel is low; Off shuts fuel flow for maintenance or storage. Using the reserve position as intended helps avoid running out unexpectedly while on the road.

• On: normal running fuel pickup.
• Off: stops fuel for safe service or storage.
• Reserve: accesses the tank's lower fuel to extend range when needed.

Who is this for?

This MOTO1988 petcock kit is intended for Kawasaki KLR650 owners, mechanics and restoration projects seeking an OEM-compatible replacement without spending on a factory part. It’s ideal for riders restoring older KLR650s, anyone experiencing fuel leaks, intermittent fuel delivery, or a broken selector, plus workshop operators who want a value-oriented, ready-to-install assembly that includes hoses and clips.
