Hey guys, I have a 04 YZ450F and upon my last ride this past fall, I go to start it one last time and I grab the decompression lever and its stuck? We were riding on a fairly muddy trail system all day and I just figured it had some gravel in the lever hinge area. After a thorough pressure wash it appears to be still stuck and I cannot depress the lever at all? Any ideas? Been riding for many years, but pretty green to the 4 stroke world. Thanks for any help or suggestions.
