Let me clarify. If you are aiming for 1200 RPMs then you are trying to set it too high. If you end up at 1200 then don't worry about it. I have no idea what my idle speed is as far as numbers go. I set it by ear. Suzuki recommends 1100 which is close enough to your 1200 spec. If it sounds too low then it probably is. You don't want a lopey Harley idle speed. It will kill the bearings.

@Batman, yep, if you used the speedo, then that would explain it. That's why I used my hand held gps. If you use a gps which is dead accurate then 6.8mph is 1200rpm. And that is likely the speed if you go by the speedo.

I checked the Savage when I got it and it's not too bad you are going a little slower maybe 55kph when speedo says 60kps, compare that to the gs500, which is out by about 12% rising to 15% in the higher ranges, which is a PITA. 70kph is 63, 80 is 70, 90 is 80 100 is 90, 112 is 100 and 125 is 110, it is most annoying.
