Thanks for your comments Bob and Grzegorz. You know, when I think about it both my A/F ratio charts have been in the rich which is why I need to now experiment a bit more with my settings.
Bob, the only jets smaller that I have at the moment which I could use are 135 which for me might be just a little too small for my liking.
I think now that I have already gone down from 150 to 145 since my last dyno, the next step I'll try is going down to 42 pilots and see how it feels then.
Regarding your comments Grzegorz, like Bob has said already, it appears it is hard to compare settings of those who still have the stock air box compared to pod filters but I think the sentiment is much the same.
cheers
