Need starting point for jets - modified 98 XR600


What would be good starting points for jetting on this bike?

98 XR600 – California (lean) model


[*]FMF muffler

[*]Snorkel out

[*]Early needle

[*]97 intake manifold

Any suggestions based on your experienced would be appreciated.

If I remember right I had a 68 primary and a 158 main jet.

I had to raise the needle on the FMF pipe. The primary jet was 1 over stock but the needle was the key on my FMF. When I went to the White Bros. I had the needle in the stock position.
