You shouldn't have to fight your gas cap — or wonder if your tank is getting enough air.

On the YZ250F and YZ450F, the tight packaging around the tank and airbox forces the stock rubber vent hose into an unnatural bend. The vent hose kinks. The tank can build pressure without proper ventilation. Fuel flow can be interrupted — right when the engine needs it most.

The XPR No Kinky is the fix.

This one-piece billet aluminum elbow cleanly reroutes the vent hose with a smooth, natural bend that flows freely — no kinks, no pressure spikes, and no fuel delivery surprises. The dual O-ring seal keeps the fitment tight and leak-free, while the one-piece design makes gas cap removal faster and easier. No more twisted vent tubes when it’s time to refuel.

YZF Gas Cap Vent Elbow

The XPR YZF gas cap vent elbow eliminates kinked/torn vent tubes associated with refueling. The elbow simply pressure fits onto gas cap post for easy install.
The elbow has rubber o-ring seals & is machined to allow the gas cap post to spin freely of the XPR elbow. The XPR elbow will ensure that the gas tank is properly vented with fuel flowing freely to the fuel pump!

XPR Yamaha Gas Cap Spout

Works as should as is very nice quality.

Only thing I think would be better is a little tighter fitment for the seals over the gas cap stem. If the seat cover popped off the Spout is loose enough it may slide off the stem of the gas cap.

I would buy again and I have recommended to others. Just something I think could be better for customer long term use.

Craftsmanship spot on

Very well crafted little modification that helps tremendously

Finally no more vapor lock, yes this is an issue for the 2023 250f. Makes fillup easier too.
