I recently chucked a set of 57-H cams in my 06 street bob. Now i have a fairly good crasp on the AFR stuff. But what i am wondering is should i screw around with the spark advance on my Power Vision tuner. I wish there was a  better way to show them. But any how  any one have advice on if or where i should make any changes. Thanks Folk's Oh it is a stock 88" with  Andrews 57H cams Rush 2.25 in baffles on factory head pipes. and Screaming eagle A/C

Well i guess it does help to show both  :smilep: But i am still wondering if i need to or should tweak them any? I have no sign of pinging in the motor and it runs strong till around 5K where i wish it had some more umph. The afr tables are 13.8 down to 12.6 of course i realize that's a moot point with out the graph. But suffice to say i feel i have them all set nice from the way bike responds. Maybe it all i can expect from my set up but i am hoping i can squeeze some more out of it some place. and no can not afford dyno time although i really love it.

if it isn't pinging ,you did good . it has plenty of timing already .
