Description Item #KIB000A

Kibblewhite takes a scientific "system" approach when designing their valve spring kits. Each component is designed to work with the others as part of the complete system. Kibblewhite's engineers use a proprietary design and simulation software, and draw on their 70+ years of design experience to create these systems. Kibblewhite's design, simulation, and manufacturing processes insure compatibility of the valve spring's force and natural frequency with the cam profile, valvetrain mass, system harmonics, and the engine RPM. Kibblewhite spring manufacturing partners are U.S.-based companies that are ISO certified. The Super-Clean Chrome Silicon valve spring wire they use is traceable back to Kobe, Japan, where some of the best spring wire in the world is manufactured. Combining the design and simulation protocols with this premium quality valve spring wire, and manufacturing processes including, heat treatment, stress relief, and shot peening, allow Kibblewhite to supply you with the best valve springs in the world.

Kibblewhite valve springs come complete with lightweight racing titanium retainers, chrome silicon springs, and lower steel collars as required for ONE engine. The Kibblewhite valve spring kit is easy to install and helps reduces valve float in the high revving engines, adding durability and reliability to the engine.

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.

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.

Q: Does the bigger ( larger diameter, heavier spring) go on the exhaust valve?
1 year 4 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:

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: Can i just replace intake springs&valves?
Over 6 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.

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)
