I am on my third valve adjustment and was wondering how soon should I be looking at a valve job? My bro's X lasted 3 years before he forked out the money. I keep them very tight and check them often, but do like to fly across them dry lakes, and have about 3500 miles on the bike as of now. I am just hopeing that all you WR owners are getting 5k out of your steed. I guess I could yank the head to check:eek: . Man do I miss 2 strokes.
