RR370 Posted October 24, 2008 Share Posted October 24, 2008 Well I finally fitted those hedman headers, got a new 2.5" system made and got the RR through the Costa Rica MOT type test. I had the screw up the mixture screws so the engine was running on vapours to pass! but once it did I backed off the mixture. I have now the headers and K+N cone airfilters on each carb. What I notice is good bottom end power until around 4000rpm when the engine starts the split and cough, pulling the choke out seems to help so I figure I need to change the needles in the carbs. Anyone done a similar set up and can recommend which needle from standard to use? Quote Link to comment Share on other sites More sharing options...
landmannnn Posted October 24, 2008 Share Posted October 24, 2008 In the old days before fuel injection it was normally trial and error, borrowing a range of needles and jets and using the ones that worked best. A bit difficult nowadays now that carbs are out of fashion. Quote Link to comment Share on other sites More sharing options...
