Here goes..... I have a 04 E Glide, 95in Bigbore, Weisco 10.5:1 pistons, Tman gear drive 590 Cams, Adjustable P- rods, Tman stage 3 ported heads, S&S roller rockers, Mikuni 45, Daytona Ignition, and running rinehart true duals. I"m getting a good bit of ping when pulling any load or a hill until I hit 3,000rpm then it goes away, the bike runs great. I have been trying to get that ping out and just went and had it dynoed thinking maybe it was a little lean?? Numbers were 110hp and 110tq. The mechanic said it wasn't lean and was running as good as it was gonna get. I would like to here some opinions on what I could do to get rid of the ping if anything??? Maybe run some race gas???? Or just try to ignore it when it happens? Oh Yeah---- timing is set at 2 and adv. curve at 2 which shouldn't be causing a problem there.
