    I am having trouble getting to the filter without taking the bike down. This is routine replacement item it can't be that difficult to get too what am I missing.

    On my blue K1 I have 126K on it and the Red K1 has only 51K. The red one is having the sticky problem, the ble never has had that trouble. Thanks, I'll check that out.

When my car warms up it will not stay started it will die unless i keep my foot on the gas petal to prevent it from dying

Change the sir-filter and fuel-filter. Also clean out the air-filter box the filter sits in. If the problem persists, remove the air-intake duct that goes to the throttle body for obstructions. Also look at the air-horn and throttle-plate. Is there carbon in the air-horn and throttle-plate? If so, carefully clean the airhorn and throttle-plate with a clean, dust-free rag sprayed with automotive solvent.

If you still have the pronlem, you might consider the engine temperature-senser.

Clean your Throttle body with throttle body cleaner or Deep Creep made by Seafoam. When the carbon and varnish build up in your throttle body get's hot, it gums up the IAC (Idle air control) valve which help moderate your engine's rpm to keep it from stalling.
If the IAC is stuck due to the gum of the carbon and varnish in your throttle body, you have stalling issues which you have described. Start with that and replace your air cleaner filter since your going to clean your throttle body.
Good luck and be safe, thank you for using fixya and post us back.

Replace engine air filter

Hi pastore -

Changing an air filter is generally an easy task to perform. Pop your hood and look for the air intake tube. This tube (sometimes more of a labrynth) runs from your throttle body to the "air-box". You can locate the throttle body by having an assistant push and release the gas pedal (while car is off) while you look for moving parts under the hood. The mechanism that moves when the pedal is depressed is the throttle body. Now trace the intake tube (large tube/hose) from the throttle body down to the air-box. The air filter will be located within the air-box. The box usually has a series of clamps that hold a cover in place. Release all of the clamps and lift open the cover to expose the air filter. The air filter should just be sitting in the air box - should be easily removed by lifting the filter element upwards. The new filter should simply drop in place of the old one. Reclamp the cover and you're good to go!.

Please let me know if you need more clarification!

Sounds like idle air control valve sticking. If i remember correctly, the idle air control valve is built into the throttle body. This is the part that connects between the air filter and inlet manifold. take this off and clean thoroughly with carb cleaner. if this does not work, then renew part.
