i am using a kent cam uprated valve springs and its had a full rebuild 700 miles ago. well i drove it hard last night felt okay
untill the morning when i tried starting it up and BANG BANG!!

i did have an adjustable revlimter but i was pissed off so i turned it off. I
have'nt taken the head off yet, so not shore if i've smash a piston
WHAT COULD THE CAUSES BE OF THIS HAVE BEEN
ANOTHER PROBLEM. It starts up very lumpy from cold then clears, but then it drives fine, but when idling it still sounds a bit lumpy also i'm using loads of fuel,and there is'nt a cracked fuel pipe anywhere, i been told it could be the air intake switch that controls fuel timing .WELL CAN ANYONE HELP I'D BE A HAPPY BUNNY THEN
