u forgot to mention that you can sell your old fi parts to make up some of the money and help save.They use PSI springs. (as of last year anyway)I use a duel valve spring kit from walsh, Witch i believe is just a kibblewhite kit.
As far as the $300 goes, totally brain farted on the valve springs. But, that is not req'd, but suggested!
Rowe...if you need any more help, you can PM any of us. Walsh YFZ helped me out a ton when I was doing my swap. I did have the quirky ON then OFF then ON to start issue when I was e-start, but a TOS elim from KMS solved that issue for me. I gutted my harness myself to save some money...but all other prices listed above are about spot on. My set up all-in-all was about $550 with the valve springs. I would NEVER go back...this set up is much cleaner, and the quad is much more responsive, hands down! I am also running close build to yours and Blue Ranger's...14:1, P&P, ATP int cam, 08 exh cam.
You will love it...start saving
