Hi Guys, new to this but love my agility so much I needed help.  I just moved and the elevation difference is drastic. Ever since getting here my scoots has ran really flat.  What I mean by 'flat' is its acceleration is noticeably slower, it struggled to maintain speed up hills that didn't give it problems before, and for the first time since I've owned it (4 years) it gave me a back fire pop the other day. I do all maintenance myself and just before the move changed the transmission oil and engine oil. Any help would be great. Thanks guys.
