i also have a question, i NEED more power for hills!!! i all ready have a big gun slip on, it runs fine with the stock jetting, but what will a rev box do to my recon? will a cam for a 250 fit mine? port and poils? bore? tell me all!!
I'm not sure on the '05 and up recons, but I BELIEVE that the only difference between the '04 and below model recons engine wise with the 250ex is the valve setup. The valves on the older recons and 250's are different. I'm not sure if that's all thats different though. Do you have an aftermarket air filter? A filter plus jetting along with your pipe should give you a considerable increase. Also I don't know if it's an option, but from what I remember you have some pretty beasty tires on your recon. Try a lighter tire such as Maxxis Razr's or Kenda Klaws. Huge mud tires really rob your power.
