I did the throttle stop, air box & baffle modifications on my 00 WR, as described in this forum and my bike has more power and revs quicker(thanks for the posts everybody). I rode it this weekend and when I would stop hard and start from a stand still as soon as I touch the throttle the engine will stall. The jetting is still stock, I also noticed that now it would start a lot easier, in most cases in the first kick. My next mod is YZ timing but I would like to solve this problem first. Alex E.
