Honda XR70R parts for carburetor and fuel service
Start with the part that matches the repair: the float-bowl gasket seals the carburetor bowl, the float valve controls incoming fuel, and the petcock controls flow from the tank.
Seal the carburetor float bowl
The XR70R float-bowl gasket seals the bowl-to-body joint. It replaces Honda reference 16010-141-305, appears in the 1997 XR70R carburetor diagram and is sold individually. Compare the gasket profile with the fitted carburetor if it has been changed.
Check the float valve
The XR70R float valve controls fuel entering the carburetor bowl. Honda’s 1997 carburetor diagram identifies reference 16155-883-005; the replacement is sold individually and covers XR70R 1997–1998. Compare its shape and reference with the installed carburetor.
Replace the tank petcock
The XR70R replacement petcock controls fuel flow from the tank and replaces Honda reference 16950-GCF-671. The 1997 XR70R fuel-tank diagram identifies that reference as the fuel-petcock assembly; the replacement is sold individually. Check the tank and fuel-line arrangement if either has been changed.
Choosing parts for your XR70R
Keep the parts’ year ranges separate: the float-bowl gasket and replacement petcock cover XR70R 1997–2003. The float valve covers 1997–1998, so it should not be carried forward to later years without a matching part reference.
Identify where fuel is escaping: the bowl gasket seals the float chamber, while the float valve controls fuel entering it. A leaking tap is a separate repair at the tank.
Choose the right fuel-tap service: the petcock replaces Honda reference 16950-GCF-671. A separate rivet-style repair kit is for original taps with that construction; inspect the installed tap before choosing between an assembly and a repair kit.
Check any replacement components: if the carburetor or tank has been changed, compare its markings and part reference instead of relying on the frame model alone.
Honda reference: 1997–1999 XR70R Parts Catalog and 1997–1999 XR70R Shop Manual. The catalog identifies its year coverage and provides the factory diagram reference for checking individual assemblies.
Fitting universal controls?
Compare universal handlebars and grips for a custom setup. Check handlebar diameter, throttle type, grip fit, cable reach and clearance before ordering. Universal parts may need modification and are not confirmed direct fitment.

Honda XR70R Parts questions
Which XR70R years does the float-bowl gasket cover?
The bowl gasket covers XR70R 1997–2003 and replaces Honda reference 16010-141-305. The 1997 XR70R carburetor diagram shows that reference. If the carburetor has been replaced, match its assembly before ordering.
Will a float valve fix a leak at the carburetor bowl?
The float valve controls fuel entering the bowl; the gasket seals the bowl joint. The XR70R float valve covers 1997–1998, while the gasket covers 1997–2003. Identify the leak location and check the fitted carburetor before choosing.
Is a replacement petcock the same as a rivet-style repair kit?
No. The replacement petcock is for Honda reference 16950-GCF-671; the separate repair kit is for original rivet-style taps. Check the tap construction and reference on your tank before ordering.
Are the XR70R float valve and bowl gasket sold as one carburetor set?
No. They are separate components, each sold individually. The gasket seals the float bowl, and the valve controls incoming fuel; choose the part for the component you are servicing.
