Moose 0926-3192 Intake Valve Spring Kit 19-26 Yamaha YZ250F YZ250FX WR250F

Stop chasing valve clearances and constant shimming. The Moose Offroad 0926-3192 Intake Valve and Spring Kit is a premium Heavy Duty stainless steel conversion designed to eliminate the rapid wear issues associated with stock titanium valves. Moto-House MX understands that serious riders need reliability, and this kit delivers a valve train that stays in spec longer, allowing you to spend more time on the track and less time on the workbench.

By converting to high-performance Black Diamond™ stainless steel valves, you can extend the life of your intake components by as much as four times over OEM titanium parts. These valves aren't just durable; they are engineered using Finite Element Analysis (F.E.A.) and proprietary software to ensure they flow and perform better than stock. With titanium retainers and progressively wound springs, this kit provides a Racing Performance edge that thrives in the demanding conditions of Central Florida motocross.

Installation Note: The intake springs for this kit include a progressively wound outer spring, which should be installed with the tightly wound end seated on the H.T. steel basewasher.

Frequently Asked Questions

Why should I switch from Titanium to Stainless Steel valves?
While titanium is light, it wears quickly. This stainless steel conversion is built for longevity, significantly reducing the frequency of valve adjustments without sacrificing engine performance.

How do I identify which end of the spring goes down?
The "tightly wound" end of the progressively wound outer spring must be seated against the H.T. steel basewasher for proper performance and reliability.

Are the spring pressures safe for my stock camshafts?
Yes, these kits are specifically engineered for each application to ensure the spring seat and open pressures (69 lb seat / 187 lb open) work harmoniously with your OEM profiles.
