i have recently bought a cobra exhaust system for my sons 300ex
im cheap so i also went without a "jet kit"

theres a K&N filter with the lid still on

i bought keihin jets instead

i have a 128 main
needle is postion on slot 4
also have made changes with the pilot jet
i have a 42 pilot, and i started with a 40

the whole project seems to be smoothly done

only problem is a decel problem i get a little bit of a pop

tried messing with the mixture screw pleanty of times with 1/4 increments


the spark plug looks great, i think im just going to have to deal with a little bit of a pop,

was wondering if anyone else has had the same problem
