Thanks for the info

Hi all, Just fitted a after market exhaust and Pod air filters on my Honda CB400 super four, The bike starts and runs fine, good acceleration through all the gears, only when in 6ht gear above 8,000 9,000 rpms she starts to stutter and will not pull if I drop the revs down she runs ok, I was told I need to put in bigger jets, I am no mechanic so would appreciate any advice. I looked at the plugs and they look light in colour. Mick
