I currently own a 2000 380 exc which I bought new in March. I have only been able to ride it a few times due to an injury but am ready to go now. We ride tight woods in the summer and desert in the winter. I am currently running a 45 pilot and a 168 main. The dealer I purchased the bike from recommended a R1468J needle which I have installed. The needle made a great deal of difference. I have been reading as well as been told that a #7 slide is the way to go on the 300s is this also true on the 380s? I also have V Force reeds and a Pro Circuit silencer. I have not been able to ride it since installing these items and am looking for a good starting point.
