xr 400 hard starting shenangins

hey guys im looking for some direction on my bike


recently over the past year ive had tons of problems with starting my bike

sometimes it takes forever and my legs almost so dead i cant even ride hard for about 20 minutes

usually i start with tipping the bike on its side letting some fuel leak out , full choke 3-4 decompression kicks then a regular kick in the past its done fine and started great lately no dice .

just this past thursday i rode for about 2 hours not only did it not start till about 10 -15 kicks it wouldnt run off of choke half choke only no choke = sputtering

then about 2 hours after i rode i tried to start it again after i washed it ( kicked it about 7 times and it was still not starting )

ive tried everything in the past new plugs air filter etc.

this weekend im going to do a new filter and try to fully clean my carb and start with a new plug im also thinking i might need to adjust the valves ( some help here would be great as well. i think a clymer manual is in my future )

help anyone ???? :bang: :bang:

thats what i figured

thanks for your input

anyone else ??

thanks for the reply

hopefully theres no worn rings this bikes only an 04 and its not raced trail ridden only


thanks for the help guys its much apreciated

bikes never been touched internally or externally next to oil changes and filter changes


if your speaking of the decompression system its activated by a lever on the bars ???
