'01 M600 when started cold, fires straight up, and seem's to rev hard when on choke, try to back the choke off, the engine then struggles to idle till warm, or rev's high with choke.
Before fully warm the bike has a low speed 'stumble' when pulling away, this is noticable, to a lesser degree when fully warm too.
The bike is totally standard.
Is there any way to fine tune the jetting to eliminate this? I'm thinking maybe pilot screw's, how many turns out are they as st'd? Are they a bit rich or lean as st'd?
I was figuring it may be a tad lean by the temperemental cold running.
Do you know how many turns out the pilot screws are as standard? Just so I have a base to work from (tried one screw, think it was about 3 turns to fully seated)
