bogging out

[khoolguy]

I got a 97 YZ 250 and when whenever i take off it kinda boggs out, it sounds like when you first start your bike and take off without warming it up, like kinda spudders. Took the carb apart and cleaned it all out and still does the same problem. Does anyone know what it might be???

check the exhaust packing for being plugged up and check that your jetting is good for the area you are ridding in.

bad gas , too much oil , fouled plug , all of the above, bad float in carb , bad float setting in carb , wrong jetting , plugged exhaust , crack in exhaust (sucking exhaust straight into intake) , dirty air fillter , did i mention fouled plug ? choke stuck closed , warped reeds , bad power valve adjustment ( not sure if your bike even has these lol) low compression , water leaking from head gasket. hmmm hope these help. http://www.race-dezert.com/vb3/attachments/old/images/graemlins/shocked.gif

I had a bike that had that same problem and it took forever to figure it out. It ended up being a clogged fuel tank vent tube.

Muffler Bearing???

Just kidding...I agree with the plug, air filter, jetting and float level. Get a manual and read about those aspects.

I got it fixed, it was bad power valve adjustment. I guess 2 screws were loose
