Yeah, I got a comment... several, in fact.
The first is that TYPING EVERYTHING IN CAPS IS THE INTERNET EQUIVALENT OF SHOUTING AND IS VERY FUCKING RUDE!!!!!
Don't do it.
Second - a 2007 Classic 650 Dragstar, which is still brand new??!!
Are you sure it's new? If not, then there is no breaking-in period and you should be able to get a good 48MPG easy enough, unless you live in one of those countries/states where they must have restriction devices by law.
If all is well and you're still getting low MPG, check your idle and fuel mixtures are set correctly, the barbs and cylinders are balanced, spark plugs are in good nick etc.
