You are a lucky blue owner. I would, during your off riding season, check your valve lash. They should be spot on, if not, you'll learning how to rebuild a 2000 wr400 with alittle over 600 miles on it! :cry: Just for thought, I went to a 48 tooth rear and that made 1st. gear very useable for trails and desert riding. Also gets me 100 miles on one tank. :cry:
