Didn't know where else to post this, so if needs moved no prob. Posted before, but starting to lean towards detonation, ignition module going bad, or something occurring when engine oil temp gets to 200 degrees, so not a real specific place that would work the best.
As some might have seen some of my posts before... after my engine gets to 200 degrees, especially on a hot day, all of a sudden the engine makes a very loud mechanical noise while riding. The idle will change while riding also, and will notice when stop at light, because will have to re-adjust my mukini idle at stop lights and signs etc, one time idle might be low, next time, will be high, and will re-adjust.
After replacing lifters (could have been collapsing, valves slapping back), thinking they went bad which didn't solve any issues. I read an article somewhere to try and turn the ignition module counter clockwise to retard my screaming eagle ignition module. I did that and the noise went way down.
When touching the ignition housing, it feels rubbery, pliable, and soft, when engine is really HOT.
1. Does this sound like a detonation or pinging symptom? Can't remember the difference between the two.
2. Could ignition module be going bad? Have been using it for several years. Or is the screaming eagle module not the ideal cone module to use for my setup as shown in my signature.
3. Checked my voes and it engages/works at 5.5 inches of vacuum.
Hot 0.590" prowler cams, ported 883 heads from branch, 10.1 compression, and 30 degree domes pistons, vance and hines straight shot exhaust, screaming eagle hi performance coil, screaming eagle wires, and regular stock spark plugs.
EVERYTHING is fine before engine warms up to 200 farenhite, measured via engine oil dipstick. Using Amsoil synthetic also, which when is hot, would be even thinner that petri oil maybe, reducing oil pressure. Because I seen the oil pressure light come on a few times at idle after riding, but idle was kinda low.
Thanks for any feedback or similar issues you have heard, or encountered.
I noticed when I was turning module to adjust, and then re-ride around the block, that around the tops of the heads was a little smoke, immediately went for a ride to cool down, then re-adjusted, went for ride, then turned off. Rocker covers feel as hot as exhaust, it gets that HOT.
I'm starting to think I might have an oil line plugged/restricted or something.
Dumb question... what happens if oil lines becomes restrictive? or even blocked? What should one notice to look out for? I have noticed that I do NOT burn as much oil, and that the oil tank stays consistantly at same level, but did change rocker gaskets.
Has anyone had an ignition module not work properly when got toooo HOT?
So hear is a pict of my plugs...

I just bought some NGK DCPR8E plugs today, but not sure that will help, I can't read plugs, and these in pict have been in for about a year.
Thanks!
