Bike still dies during idle. I have changed, plugs, FPR, battery, fuel rail, all 4 injectors, and map sensor. I still havent changed the throttle bodies, but i dont believe those will make it die during idle like it does. Bike runs great as long as im giving it throttle. Pull clutch in and slow down to stop sign, and bike dies........Bike cranks and instantly idles at about 3k rpm. Gradually it idles down to normal. But not long after it slowly drops under 1K rpm and kills itself......Im loosing my fuxin mind.....Any more ideas!!!!!!!....=-)

 

you check all your vacuum hoses yet?

 

I have checked all the ones that come 2 mind and have changed just about every little thing i can think of....Whatever it is, its really pizzin me off....Is it possible that fuel pump or fuel filter can make the bike act the way it does?...=-)

 

based on what you've provided, there seems to be a vacuum hose that's disconnected somewhere.
i know it's tedious, but you need to check all of them.

if you think it's the fuel pump, then you should try and do a pressure test.

 

This is crazy.... I am having the exact same problem on my 2001F4i.I just replaced the battery and I get the same problem. Bike starts fine.... runs fine up until 110 degrees then it will not hold idle without cutting off. If you hold the throttle runs fine. Let it go and it dies. I am interested to know if you find it to bea loosevaccum hose. If not what other options would you recommend?

Got her fixed, w00t!!!...it would help if i remember to tighten the #1 plug all the way down tight and also snap the coil pack down onto the plug, LMAO......My original problem was, plugs were fouled and there was about 1gt too much oil in it. Thus putting excess pressure on the crankshaft and kill the bike at idle....anyways, i changed the plugs first, but i forgot to tighten #1 and push the coil pack all the way down........So i originally fixed the problem with new plugs and an oil changed....I just fuxed myself the 2nd go around, LMAO.......=-)
