Hi I have a 97 xl1200S sportster w/DFT conversion. Had some major work done late winter carb. rebuild, new rings both piston. My question is mpg I was between 38 to 40 when I first got the bike 4 years ago. now with all I had done to the bike so it would be good for year. I'm now getting 25 to 30 What's anyone thoughts the dealer I took it to said they can put on a dyno to fine tune for an fee. Thanks in advance
