Hyosung GT 650 s sætter ud efter høje omdregninger

[Johnny Rasmussen]

Min Hoysung GT650 sætter ud og køre ujævnt og med for mange omdrejninger i tomgang når jeg har været over 5000 omdrejninger og stoppere først når maskinen slukkes.
Kan du hjælpe mig kan ikke finde åprsagen.

Hey, Sorry I could not fully understand what you were saying, the translator i use is very rubbish. Is it possible to send a reply in English and upload a video   (youtube, instagram , dropbox etc)  copy the link here.

Maybe we can see what the issue is with our eyes too.  We have a few 650 owners on this forum and one of them did a good ECU Diagram in tutorials section.

There is also the service manual in this forum,  find one that matches your ECU / Year of bike = > Get error code and tell us.

Too high idle-RPM… check first; throttle-wire, condition & adjustment…:

• does the throttle feel smooth, does the throttle go to its (low)end-point when dropping the handle? Wire adjusted too tight?
• check for any vacuum-leaks…
