2004 suzuki LT-z400 problems. HELP!!!

[kkkyle]

I just bought a 2004 Suzuki Z400 from some guy in utah. i brought it all the way home in wyoming. it runs fine at first. then after awhile of riding it starts bogging down and choking up and dying. then it won't start for awhile like it's over heated. but the Temp. light and fan don't turn on. it's some kind of endurance problem. any help?

That's odd...is it getting enough fuel? Are there any modifications to it?

How long is a while, I have the same quad and my fan usually comes on within 5 to 10 minutes of riding. Also check to make sure the radiator itself actually has coolant in it Ive found mine empty before but the fill bottle on the side was full. Without fluid the sensor on the radiator wont read to turn the fan on. Im not sure this will fix your problem, but I'd check it your fan should be coming on.

being a 2004.

check your choke cable.

There are lots of LTZ400 that the choke plunger in the carbi or the cable gets rusty and when you pull the choke on, it cant turn off. Even tho you and push the thumb lever back to its starting spot, the plunger can still be out making the bike run rich with fuel and stop the bike and kill the spark plug.
