Having problems starting my 2004 CRF 250. I need someone's help.?

XR is correct, the 2004 CRF250R is notorious for valve adjustment issues. This was corrected in '05. One of the biggest signs of valve adjustment issues is a bike being very hard to start. Whether that is the issue or not, if you haven't had the valves checked you need to do so right away. If they get ruined you are looking at serious money. Titanium valves are expensive as is the labor to install them.
