Needed new valves and springs for for my engine with putting a 440 big bore kit on kfx 400 have it in the shop right now getting all the engine work done so it is ready for the races hope she runs good with these valves that are said to be better than the titanium ones thank you motorsport team
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.
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.
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
Next time you rebuild your top end make sure to use kibblewhite.Do it right the 1st time.
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.
