I am helping a friend from Sweden that is not too good with his English. So I am helping him out. I am pretty much a carb guy, so I need some help.
He has a 2003 RK with FI and a stage one set up (SE muffs and intake). When he starts his bike up the engine light will come on for a minute or so. During that time the bike coughs feels like it is going to die at slower speeds/RPM, but it never quite does. The light will go off after a minute or so, but it never really want to run well at lower speeds/RPMs.
The bike will runs okay at higher speeds/RPM.
He does not know if the bike got a "flash" with the stage one (he bought used) and it does not have a "Power Commander" or equivelent.
I also asked him to check the plugs to see if it could be determined if it is running lean or rich...but I do not yet know that information.
Can someone give me some assistance on what to check for? or what this possibly could be?
