    Sick of doing valve adjustments yet? You’re not alone. Pick up a Steel Intake Valve Kit from Pro X for some valves that will last a seriously long time without giving up any performance.

    Pro X manufactures these exhaust valves so close to OEM specs you can reuse the same retainers, bases, and seals without any modifications. It all begins with a 21-4N stainless steel valve that is black nitrided for an unprecedented combination of core strength and surface friction reduction. Then comes the chrome vanadium, heavy duty springs built specifically to handle the extra weight of steel valves. Even at high rpms these springs hold a tight seal so your valves won’t flutter or float even after seasons of being heavy on the throttle.

    Experience what it’s like to spend your time riding instead of checking clearances with a premium set of components in the Pro X Steel Intake Valve and Spring Kit.

    Specs:
  • More durable than OEM
  • Reduced clearance adjustment
  • Pro X tappet sets available
  • 21-4N stainless steel valves
  • Kit comes with all valves and valve springs
  • Valves have black nitride coating
  • Heavy duty chrome vanadium valve springs
  • Fully compatible with OEM retainers, bases, and seals

must have for crf's

Comments On Oct 23, 2013:I have a 2005 crf 250x. I race harescrambles. I used to have to adjust my valves every three races or so. I installed these at the beginning of the season and my last race was about a week ago. I have had zero problems with my valves since installing these.

Fixes Honda Valve Problem

Comments On Sep 29, 2013:Been over a year and only had to adjust these valves once because when there brand new they need to be worn in and then they go forever. I was adjusting my oem valves every 10 hours but if you buy these there is no problem. I also noticed a little more low end power because these weigh a little more but I love them

Great Valves

Comments On Jun 11, 2013:These valves are great. When I rebuilt my bike I redid my head (cut the valve seat) and then installed these Pro-X steel exhaust and intake valve kits with new seals. Bike started in 2 kicks and has been going strong since. It's been about 3 months and I've been racing nonstop since then with no problems. Still starts in about 2 kicks, and I haven't even had to re-shim them.
