RK 2001, MM EFI, all cables checked. this happened during my ride yesterday.

At a x-ssing light, my bike stopped running at idle. I had to try almost 10 times before the bike started again. It run Ok untill i stopped at a friends place and since then the bike did not want to start again. I went to a dealer and bought a new battery and sparkplugs. It did not help.
The fuelpump is working ok but the idle speed control actuator seems not to set itself, even when you force it into any position. Strange ? Normally it sets itself to a position.
My friend had some starting gas/fluid and sprayed it into the thruttle body when starting. It did help and the bike started.
When keeping the RPM at +- 2000 it stays running. but dropping the RPM to idle speed the bike stops running. Restarting without the starting gas/fluid is not working.
It is as if the ECM is not sparking or giving enough fuel. When cheching the sparkplugs it shows enough sparks...

The engine check lights stays on when the engine is running...
Not enough volts? Some sensors gone banana's ?

All EFI specialists, please advice...

Check the hot and cold idle settings. You will need the shop manual for this.

About once a year I have to adjust mine a little because they are adjusted by turning little screws (the manual wil explain).

Is the engine light flashing? Again you will need the manual to decipher the flash pattern.

Keep us posted.

Problem is solved

despite that a visual inspection showed all fuses ok, by using a ohm meter, we found one 5 amp fuse that was giving intermittent contact/no contact. After replacement the bike started immediately. The bike was already towed to an indy and he tuned the MM to run perfect ( it took a while since the engine had to be hot and cold )....

check your crank position sensor the one on my 1999 ultra failed this year. It is not uncommon for them to fail.
