How does the JD JETTING kit perform on the 300 XC? I need to re-jet my new 2007 300 XC and all the jets I have are too large; therefore, I need to purchase all new jets for my new toy. Before I run off to my local cycle shop and place an order I am considering a JD JETTIN KIT for KTM. I purchased a JD KIT for my YAMAHA WR250F (which I traded in for my KTM) and ended up going back to the stock jetting. I could never get it to run the way I needed it to run. I am also condidering a FMF JETTING KIT but I have not seen any reviews on the FMF KIT. Jost asking for someone's 2 cents. I also posted this on the KTM 2-S thread.
