Here is Bike and engine info:

Now a 103 (pistons and jugs) with SE 255 cams. About 10000 miles since build
Harley SERT Tuner. Dynoed at 1000 miles after build

CVO mufflers with 2 inch Fulsac cores
SE stage 1 Air cleaner.

Recently I have noticed a slight intermittent knock after about 2 to 3 minutes of warm up at idle speed, can actually feel it as I roll bike out of the garage. Never hear it under power or engine rev. It doesnt happen while sitting at stop lights either.
Bike seems to run great and I have not noticed any pinging,

Thoughts??

 

Only in neutral? Clutch pulled in or out? Could be the infamous neutral rattle coming from trans possibly

 

Only in neutral. Clutch out. just a slight thump with no real rythm and no change in idle when it occurs

 

The Verdict: Not a timing knock. It was the Compensator, which has now caused a chain reaction on damage. Thank goodness for ESP
