Bought an 03 firecat 700 efi, just wondering what are some good mods. Looking bang for buck.

Get an inline fuel reducer, check your heads for squish, some 03's were right out to lunch, you need .058" of squish when finished. Try a 2.5 timing key, all for under 100.00 bucks.
If you wanna spend more there is a lot to cut in the ports on the 03 and a clutch kit will help considerably.

Not to sound like a smart ### but how about riding it for a while stock. That way you get a feel for what that particular sled might need as far as mods. Each sled is different.
