Valve Springs
Has anyone ever removed the cylinder head for a 15x and measured the valve spring installed height. I need this info to get a heavier set of valve springs, and i do not have a head removed. This info will save me from removing the head.
If you have a head removed let me know and i will explain the meaurement that i need.
Thanks in Advance.

shawn i will put your springs and retainers into our motor but i would like you to provide me all the necessary info relevant to you kit, eg spring pressure, weights, material that they are construced with.
I was looking at getting Kibble white to make us a set as we deal with them for other sidecar race valves,springs and retainers.
What constant rpm do you think they are good for as i need to them to be able to handle 8000rpm

They will handle a min of 10,000 RPM. .420 lift easy and are over 60% stronger spring pressure than stock. The kit is much lighter with Titanium retainers.

Nitro, how much do you charge to install your springs?
I would seriously drive there ,and leave the ski for a day to get this done!!
Slightly off topic ,but do the F15X share the same springs as the 12X models?
