I just got my new 06 YZ450F and everyone was right, the jetting is way to lean. I installed the 170 main but when I removed the old pilot jet I noticed that it is about .187" longer then the new 45 pilot jet, is this normal or did they give me the wrong jet?. I checked all the bearings for grease and everything was fine. The only problem I found with the bike was that the filter had zero oil. I plan on heading to the indoor track Tuesday to break her in so any info is welcome.
