Super duke high idle

Post by Roy » Fri May 31, 2019 3:23 am

Hi everyone,first time ktm owner and v twin owner,do all of these sdr’s idle to the moon? Mine seems to idle from 1900 rpm to 1500 rpm.never idles below 1900 in cold weather and very seldom at 1500 or below.very annoying in town sounding like its running away at a redlight.

Finally got to the bottom of this for anyone with the same problem.turns out it was the micro switch under the clutch lever.mine for whatever reason looked like it had been hot and deformed,and the button was locked up.replaced with a new one and all is good.

Cheers Roy,

Well spotted!

Had a similar issue on my 14 caponord 1200...... and learned to be very careful when cleaning/working on these fancy electro-technical wizbang bikes, keeping cloths/hands away from under the levers so as not to accidentally dislodge any micro switches .... the KTM ones are different to the Aprilia ones, but I guess could be affected the same way. An owner once fitted accessory levers and installed the switch incorrectly. He had the same issue as your's and he posted the solution once he asked the forum for a photo.....

Just for info..... note the gap for lever out position... the hooked tip looks like it was designed to be holding the pin, but it must not make contact until the lever is squeezed.

PS Approx 1500 rpms is the proper idle for these engines...... super light internals and 13.6:1 race compression engines etc etc. The bonus is that the battery is being charged while idling at traffic lights, unlike older bikes losing charge at their 900-1000rpm idle settings :) .
