2009 kx450f hard to start cold or hot - Motorcycles

That is an EGR valve or EGR temp sensor code or a secondary air injection code. Do u have hard starting hot or cold? Get that system checked its rough to do from here. Good luck

Start by checking your engine coolant. If the level is good, let it warm up and feel the heater hoses. They might be hard to find. They look like radiator hoses, just narrower. If both hoses are hot, you may have a problem with the blend door. It controls the temperature of the air coming out of the vents. Good luck.

does the hot/cold control knob feel like it is moving something or is it very hard/easy to turn ? sounds as if the hot/cold setting is stuck at hot would need to strip back heater control panel and follow the control wire/cable to the heater box where a flap opens and shuts for hot or cold air and see what is happening ,cable may have broken , flap may have come off it's hinge won't know until you get a look at it , the engine isn't over heating is it ?

Not for normal driving, a good quality oil grade SN or better is fine. If you drive hard, tow a lot, or drive in very dusty, hot or cold climates, a synthetic oil eg Castro Edge, is a good idea.

If not leaking its the head gasket

Check and make sure your belt is not worn, if it slips under power, then your compressor will not work. Also low Coolent in your compressor will cause it to run sporadically.

Or your vacuum that runs the hot to cold air valve is leaking, check all vacuum hoses for leakage.

The serious problem would be a the plunger type vacuum actuator to have a hole in it, if so equiped, They can be hard to get too.

The engine isn't broken in yet, and will probably need to be choked to start in the cold.

There is no reason for the idle to take 10-15 seconds to slow to normal. perhaps you have a vacume leak. check all your seal and gaskets between the engine and the carb.also when it is running spray gummout spray or equivilent around the gasket edges between the engine and the carb, if the idle increases when you spray then you have a vacume leak. (intake leak). It may be that this is causing it to be hard to start when it is hot.(not getting enough fuel)
