Must Have!!

I did a complete rebuild, bought kibblewhite valves so these springs were a no brainer. Dont put money into a motor and reuse old springs, buy a quaility built spring and get the performance you need at full throttle.

Best valves out there

I put the kibblewhite valves, and valve kit in my 05 rmz450, and 05crf250. they are the most durable and reliable parts out there, I ride the dunes a lot and never had an issue with anything so far.

Great Product but costly

I got a Honda CRF 250r 05 model which love to eat the valves up, and with that and not enough oil I blew up the whole motor, so I rebuilt her all the way and added a nice addon the valves, they bring alot more power and hold alot longer and dont have to be adjusted like the dumm old oem ones do.


dose this come with springs too

Great springs

Everything you need to replace your springs is included and it is all really high quality stuff. Its really easy to install and prevents valve float. I installed mine on a 06 kx250f with kibblewhite valves and stage 2 Hotcams. Very good combo and adds a little durability to your top end along with the power increase.


Excellent product, good replacement for stock components strong and durable and have had many hours of trouble free riding comes with bottoms seats and retainers.

I don't see the valve seals in the description, I was wondering if the Oem valve seals will work on these valves?

Q: Does the bigger ( larger diameter, heavier spring) go on the exhaust valve?
2 years 6 months ago
It's a 2010 crf450r putting my head back together and the springs got messed up . I need to know where the different springs go. Or if you could measure the outside diameter of the spring on the intake kit that would also tell me. Thank you

A: No. The stock intake and exhaust springs from Honda are different sized. You may need to measure the springs to determine the differences if they are not marked. Also you can contact Kibble White direct as they can answer more technical questions better:
Q: Can I use Wiseco titanium? As long as they're one piece valves I figured its fine but it's best to ask?

Q: Would these springs be strong enough for stage 2 hot cams or are they designed for stock cams?

Over 3 years ago Location: Portland, OR, USA
A: You should not have any issues running Kibblewhite Valves Springs with your Stage 2 Hot Cams. This is a Racing valve spring kit so it would be an upgrade over the OEM valve spring set up.
Q: Does the compressed coils face the head? or does it matter?

Q: Can i just replace intake springs&valves?
Over 8 years ago
My exhaust vales r fine,can i just replace intake valves&springs?Or should i replace exhaust springs too,and use stovk valves?Or do i replace exhaust vales,springs ,along with intake?

A: If you are wanting to run kibblewhite valve springs you will need to run their valves along with them so I would recommend replacing both the intake springs and valves and the exhaust springs and valves at the same time.
Over 7 years ago Location: bozeman, mt
A: depends on how you ride.. if you like to bounce your bike off the limiter, which is probably part of the reason your intake valves are fried to begin with, then DO NOT run kibblewhite springs with OEM honda valves.. if you are repairing a hammered bike that won't be abused, you could probably get away with using an oem valve with a kibblewhite spring and/or using a kibblewhite setup on intake side and leaving oem on exhaust.. the stiffer kibblewhite springs are made for the heavier and more durable stainless one-peice kibblewhite valves, you will rip your stock 2-peice friction welded titanium valve in half, i know because it happened to me.. destroyed my entire motor, spend the money on the entire kibblewhite spring and valve kit and not worry about your valves for a long, long time. (after break in/ valve seating period and re-shimming, of course)
