I bought a JD jetting kit for my 2004 crf250r a while back. I just got a 2007 crf250r and the jetting is a little lean. Would I be able to still use the jd kit from the 04 with the 07. My other question is can I use valve shims that are from hot cams that were for the 2004 crf250r on my 07?

Best to ask Mr Dean about his products and what they fit.

The valve shims will be the same diameter and can be used if they are of the thickness that allows you to stay within the specs in the manual.
You must use what the feeler gauge says you need. Valve lash is an evolving thing, and is always changing. The manual gives you the range of thickness it must remain to be correct.
