Hard starting WR250F

Dec 19, 2001
The last couple of rides, I have noticed that when I push the kick starter to where there is resistance and then pull the decompression lever and nudge the kickstarter down 5 degrees or so, there is no resistance to my kick after that. For the last 80 hrs. this worked great. Now, I have to nudge it a couple of degrees to get it to work. Other than the high idle required (because the jetting is a little lean down there?) it runs great. Maybe my valves out out? I haven't checked them in almost 20 hrs. In previous checks, I have never had to adjust them.
