If your not confidant in jetting it yourself and no dynos will run it then i would stick with the stock set up. No one can tell you what jets you need to run as every bike is so very different.
If you really want to fit pods, try going up some stupid amount of jet sizes and work your way down by doing plug chops. Maybe go talk to someone who races MX in SA, they will be able to give you a little advice if the dyno place wont help. You can also show them your plugs.
As with all this stuff.... dont do what i do and go weaker. Go richer!
At the end of the day if the bike feels right it normaly is. Dynos are good but what sometimes looks good on a graph can be crap on the road and the oposite counts too.
