I'm sort of a noob when it comes to wrenching on my bike ('06 WR250F) and I'd like to install a JD jetting kit. I can do basic oil changes and stuff like that. How much time should I set aside to tear open the carb and install the necessary jets and needle? I'm also planning on putting a #40 leak jet in to cure the off idle bog. Are there any special tools that I'll need? I've got the basics (screwdrivers, rachet, sockets, wrenches) but nothing fancy. Or is this something that a noob should avoid doing? Last thing I want to to is bust up my carb. Thanks all!
