Hey guys, i just picked up a new drz400sm from my dealer, and was wondering if dealers would usually do things like re-jet a bike for you if you brought the part. I have never had a bike like this, or had to do anything like this to a bike, and would rather not mess it up. I figured i would ask around before going to my dealer. I've done everything i can do to the bike, and the only other thing i've seen that i haven't done yet is a 3x3/re-jet. I have an exhaust from MRD Racing on the way, but figured i would look into doing the 3X3 and re-jet first, i would just rather have someone else do that as i couldn't really find a great, in depth tutorial online. Any help would be great.
