Questions & Answers
Was wondering if these would work on my 2004 fxd with fueling 543 cam chest kit with one piece push rods
By Todd C.
Yes, this kit would be a most excellent match for your bike's setup. Just choose the .600" valve lift with steel collars since there's no need for heavier valve springs (unless you're planning that upgrade down the road) than that. These components are more than up to the task of working with your engine as you have it set up.
Can I run these with a stage 2 hot cams in my 2004 Ltz400
By Gunner M.
Yes, this particular valve spring kit would be an ideal match for a high-performance engine build in your LT-Z. Every component in the kit is engineered for better durability and long-term reliability when compared to the stock component you'd be replacing.
What is the rated rpm these valves are made for and would these work well with stage 2 cams on my kx250f?
By Nolan
There's no published RPM limit noted anywhere in Kibblewhite's data. I can tell you that these kits are designed to withstand performance engine builds of any kind. And yes, they will certainly work well with stage 2 cams. Buy with confidence!
Does this come with all the valve springs for 2006 kx450f
By Jwinger92
Yes, all the valve springs needed would be included.
Do I use both springs supplied with kit for each valve? Only had a single spring on each valve prior.
By Kenneth
2008 Polaris 800 Ranger RZR.
Yes, you are to use the inner and outer springs for each valve included in the kit.
For my 85 ATC200X, do these come with retainers?
By yury
In the case of the ATC200X, the kit comes with 2 valve springs, 2 titanium retainers and 2 steel base washers.
