Kibblewhite Valve Spring Kit

Fit:
-14-18 Yamaha YZ250F / WR250F

Kit includes: Dual Springs, Titanium Retainers, and Steel Base Washers

These kits are only recommended and designed for stainless valves.

These valve springs are good to .395" of valve lift on the intake valves and .370" valve lift on the exhaust valves. These springs also include titanium retainers for the lightest retainer possible, allowing for increase RPM and lighter spring forces. Sunk or Shortened Guides may be required for to clear higher than stock valve lift.

*The inner valve spring registers on the O.D. of the valve guide. If shimming is required be sure that the inner spring can still register on the valve guide*
