Free mods but no jetting ?

I have a 03 WR450 and live in Ohio. I've taken out the plug in the pipe, cut the throttle stop, and removed the snorkel for the air box. I haven't re-jetted but it's running great! My question is am I hurting anything by not re-jetting ? And if I do re-jet will it be worth all the hassle. I just like to ride and have little time to tinker with the bike. I don’t want to be down a week trying to get running right. By the way thanks to everyone for all the help so far

You should be OK with stock jetting down to about 40 degrees. Colder and you will be too lean. :thumbsup:
