yz450f jettin in australian conditions

I am running a 2006 450f in hot conditions in central Australia, its usually about 30 - 35c and low humidityI will be running a FMF q4 slipon, gytr filter and 13-1 compression with a fresh top end, does anyone have a solid jetting set up for these conditions?

It backfires terribly during decel and starts like a bitch at the moment and most of my riding is hard pack trail riding.

Any help is appreciated
