I have a 1999 XX with 6500 miles. I've only had it for 4 months. It seems to have a rough idle. When cold it fires, and will run real rough for a few seconds before clearing up, or stall. After a few seconds will idle upto 2000 rpms, then slow back down to a normal idle when warmed up. Even when warmed up the idle is a bit rough. I run the idle at about 1200 RPM's just to smooth it out a bit. The bike runs great otherwise, and has plenty of power and normal MPG's. I changed the plugs and airfilter, as well as added injector cleaner to a tank of gas. Is this normal for an XX to idle rough, and stall once or twice when started cold. I expected a fuel injected bike to be smooth?
