I'm wondering about the setting on the cobra needles that were installed with the pipes. Is there a "stock" setting on these needles? Also what do the needles do? what does changing the position of those TINY jesus clips do to the whole arrangment?
When I bought my 2002 it had Cobra pipes and needles. I installed new take-off Interstate exhaust and didn't touch the needles. The clips are installed in the second from top groove. I'm pleased with the performance and mileage.
The needles are tapered and meter the flow of fuel through the main jets. Moving the clips up lowers the needles restricting the fuel flow.
