dont be afraid to give it a try on your own. if you have a service manual, it pretty much explains everything. if you dont have a service manual, find one. it will be your best friend. i just this year started getting into doing my own work on my 03 wr and i am by no means a knowledgable mechanic but it has instilled a lot of confidence in my abilities. now as far as jetting goes, you dont have to search very hard to figure out that every bike is different when it comes to jetting. so you cant really ask someone what they run for jetting and expect to have it be perfect with your bike. but, it should give you a decent starting point. a lot of people on here have had really good luck(from what i can tell) with the jd jetting
kits. they come with pretty detailed instructions and recommended starting points along with a large assortment of jets. worst case scenario you do it on your own you fire it up and realize that what you did was wrong. so you figure out what part you did wrong and change it in small increments. do some research about jetting on here and get a good understanding of what jets do what in the carb and apply that to where in the throttle position the bike is having issues. there are plenty of good people on here that have a crap load of knowledge and good info. search around, dig into it, learn a little about your bike, and feel really good about the work you have done when you hop on your bike and smile away at the good job you have done knowing you did it yourself.
