I have recently started running a go 7 port and its running strong on a dyn 053.. great motor smooth with long legs and a stout bottom!
I remember a while back reading that people were dropping a head shim after break in at about 1.5 gallons.. I am almost too that point and the motor is starting to come alive. was wondering if any one has any pointers on how much to take out. sorry I dont have more time to re read a couple hundred posts.
I am running 30% on Od 99t or 97t plugs, thanks in advance
