Hi all
here are some photos of my modified twin nostril. I have streamlined the exit vents and extended it down to abut the ducting behind the radiator. In addition to the ducting I have installed an aluminium radiator custom made by Docking Engineering that only has a single wide core. This aids cooling by allowing the air to smoothly pass through the radiator without turbulence thus reducing the pressure build up in front of the radiator.
I would say that your spring rates are about right however your tire pressure is 5lbs to high.
Regards
Chris
