KTM 620Sc 1998 Running badly

Discussion in 'Bling and Appearance' at netrider.net.au started by Sas, Oct 27, 2006.

  1. Hi All,

    I have a KTM 620sc 1998 model, that has just started playin up. When it is cold it runs and revs fine but after about five mins of riding it breaks down when you open the throttle. I have cleaned out the carby (didn't help) and replaced the spark plug, which helped a heap you could ride for longer before the breaking down occured. The bike starts real easy (hot or cold) and idles perfectly it just hates getting revved. Any ideas on where I would look to fix this problem?


  2. Cmon guys, someone out there must have an idea of what I should check!
  3. Only a couple of KTM owners on this site.

    I'd suggest Google and find some KTM specifc forums or you can try this one www.thumpertalk.com
