I have recently acquired a 2004 950 Adventure with a little over 25,000 miles, she has recently had a full KTM service including the valves, prior to this she was not used for about a year. Sometimes when I start her from cold I can hear a loud clacking noise from the right hand side of the engine, this does not go away until she has been ridden for a while, sometimes when starting from cold there is no clacking noise? Any ideas? The other issue I have come across is that when I am trying to hold a steady speed of say 60, 70 or 80mph I can feel a very slight lurching back and forward? Thanks for your help.
