[QUOTE="cp380sx, post: 112416, member: 21323"] The pipe should not affect your jetting too much if it was good before the FMF pipe. To get it just right you will need to get the bike warmed up then do some full speed plug checks. Run the bike up the longest slight uphill you can find in 4th or 5th gear then kill the engine at speed. Pull the spark plug and it should be light tan on the ceramic. Go up or down on the main jet and retest until you see a light tan ceramic. Do the same thing at half throttle to set your needle height. Cameron [/QUOTE]
