Just bought a new 2008 M1000

[Jeff 2010]

I just bought a m1000. it has 490 miles on it and bunch of add ons including a DD can and pipe with a boondocker fuel controller. It tops out at 50miles an hour on hard compact snow. From 0 to 40 miles/hr it has no problem but after that its seems to just rev up and pick up no speed. any ideas as to what might be wrong??
