While working on Venuris I also modified a needle and spray bar..Again no big power gains ,but it did help with making tuning easier.By Sharpening the tip, of the needle, to a longer point,The adjustment was much finer ,than the blunt tipped needle.I also, had to change, the spray bar a bit.That part was shortened for the needle to bottom out. I also opened up ,the fuel outlet.That worked well with the Needle changes..But still, not the answer. for more RPMs.
