i had to ride my uncles bike home.
he has a 2000 road king classic.
it has a 95" stage2 with the power commander.
it has the older ecm. magnetti marelli.
the bike will NOT hold an idle. talk about dangerous.
someone mentioned to me it may be the et sensor.
has anyone ever experienced this problem??
i don't want to ride it 2 hours to his house like this.
also, besides having to have Popeye forarms to pull his scorpion clutch, it doesn't always disengage. to many springs?? not enough oil??
any help will be greatly appreciated.
thanks in advance.

King,

On the scorpion what you can do is put in the alternate springs you must find out which combination or which set he has in there red, green, gold or a combo of them.   You can help it with an easy clutch install its a pretty easy job and it will make the pull a lot easier, but my guess is that it is over springed which is not hard to do.

2 things you can check on the idle is with a feeler gauge you can check and see if you have 25 to 32 thousands clearance under the butterfly or whether the butterfly is closing to tight.   There is a set screw you can adjust with regards to find tuning the MM system, but unless you know what your doing I would have a dealer do it or someone that understands it.   I have not had a sensor do that on my earlier bikes, but maybe someone else has.   I have seen several bikes with issues idling because of the intake / butterfly.

On the MM systems they can be a pain but once you go through the hot and cold idle set up along with the tps adjustment in that process they will run better. As make sure if you do that , the t/b has the red injectors in it if not upgrade as the black injectors are way too small they did not even work well in a 80 evo. That system was dropped as it was extremely problematic for HD.

not really to sure what you mean about the butterfly.

the bike has a bigger throttle body on it.
i think it's a 43mm or something like that.
i don't want to go crazy, but i guess i will have to take it to the dealer.
my uncle has always been good to me. time to return the favor.

as far as the clutch goes. i'll let him deal with it when he gets better.
i have no idea what he has in it.
i just need to get the bike to idle so i can bring it back to him.
thanks.

King,

If you take off the air cleaner and your looking at where the air goes into the throttlebody if you turn the throttle a little bit you will see the flap open up allowing you to see into the throttlebody.   That flap that opens and closes is the butterfly.

got it.
does that effect the idle even when the bike is wamed up??

[GMR-PERFORMANCE]

If it is a bigger t/b it was more than likely bore at BC. If you move the idle screw you really need to go through and set hot and cold idle. as moving the screw is going to skew the TPS sensor as well. Plus the MM system needs to be powered down to be able to correctly under stand that you made a adjustment. It is covered in the service manual. i will see if I can scan it and upload it.

Thanks.
the bike is a twin cam not an evo.
does it make a difference??

[GMR-PERFORMANCE]

No it does not the same set up is used. The system was not changed much at all from evo to T/C hence the amount of problems it has. It did not take hd long to know that it was a problem child and they went to Delphi, the softails was switched first then two years later the baggers. 2000 was the first year for it , then the baggers went to it in 02. It i recall correctly.
