RicKsTa Posted July 4, 2015 Share Posted July 4, 2015 Hi all,Fitted a m4 gp exhaust not too long ago and pulled my plugs to check how lean it is running.. it's popping quite a lot on deceleration which I expected but I thought with it being such a short can it would almost definitely be running leanA pic of one of the plugs.. am I right in thinking this just looks normal.. it isn't white or soiled heavily so seems to be running fine.. just wanted to double check as last thing I want is a hole in my valves etc http://i1240.photobucket.com/albums/gg483/rickstaa/Mobile%20Uploads/phpYs9RdPAM_zpsatks4fok.jpgCheers!
