Problem with 2001 RC51

Bought it 2 weeks ago and has been running fine until monday-bike does not idle unless you pull the choke out alittle. In the mornings it would start fine and now you have to pull the choke and give it some gas to get it to start. Have adjusted the idle and still having same problem so wondering if anyone has any ideas what it might be or what to start looking at. Except for this problem I am very happy with the bike and like it better than my TLR. Thank you for the help.

Try and give us a bit more problem symptom description.
A problem usually occurs either due to a failure or by being induced.
If no recent work or changes were done, then it's a failure to some degree.

I agree but I have know idea where to tell this guy to start looking.

After its warmed up alittle can you push the knob in and ride or do you have to leave it pulled out?

The bike will not idle when warm unless the choke knob is pulled out alittle bit. You have to open the throttle to get it to start both cold or warm. Nothing has been done to it and the bike ran great until last monday.

In the interest of adding more data to the problem...
Have you tried to jumper the service connector to see what possible fault codes are reported on the FI indicator?

no-where is the jumper located and which pins do I jump to get the codes. Is there a site that shows what the codes mean.

On my bike (an SP2), there is a green 2-pole connector near the ECU.
With the ignition off, jumper the two contacts, then turn the ignition switch on.
You should see the FI indicator flash in sequence of blinks if any codes are found.
There's a slight paused between sets of codes, so watch carefully.
Also, it keeps a history of codes, so you may be fooled by a past problem that wasn't cleared.
Count the blinks and let us know.

I got a honda man. with my bike. My god its like a bible! How the diag. stuff is like an older OBD on a car. And you can count the numb of flashes the FI light makes and it gives you an idea where to start the diag.

Yellow: Get the manual, it would make finding things out easier. Sub knows his stuff on these monsters! He can prob help you.

You're far too kind.
I only know what I know from having mine in pieces last year.
A lot of work, but I really enjoyed getting my hands dirty again.

Well, sub remember when I thought I had a pinhole in my left Rad? Well, come to find out it was the clamp going from head to head. SO I took all the plastic off, and tightened up ALL of the hose clamps. Found out that it took care of my leak! So that saved me alot of cash from buying a rad. So I took that money and bought an undertail kit! I will post when I get it in the mail and installed!
