Replaced my 08 YZ450 with an 11 a couple of weeks ago. Loving the bike so far, I loved my 08 but the 11 is way better in lots of ways. I also got the programing computer and did the MXA soft map. Makes the power way more usable. The one problem I'm having is starting is not as good as I had hoped for. I'm at 5500 feet and was wondering if changing any of the mapping would help with this. Low rpm fuel maybe? Thanks in advance guys.
