I don't get it "pinging" is early detonation of the fuel on the compression stroke. How often does HD want you to clean the pistons off. I gunna look in their store for a dental pick to scrape the carbon. Sorry but thats such a load of buiishlt! Get access to you ecm and change the map to stop the problem.

Guess I should have said clatter. Mine does not ping just push rod clatter that they say is normal.

If you spray something in to the intake to clean the carbon off the pistons do you have to do an oil change? Would seem like solvent would contaminate the oil...just wondering.

Seafoam in the gas,nor any fuel additive will help with carbon in the combustion chamber.
Water sprayed through the intake will break out chunks of it and a piston soak will also work.
Seafoam makes a spray that you can spray in the plug holes. Stuff helps but doesn't eliminate the issue.

Haven't noticed my 103 is more noisy than any 96 that I have owned. They all sound like a can full of bolts. LOL I did get pinging on my 96's and have it sometimes during acceleration with the 103 But got rid of it with a tuner and timing retard on the others. Gonna do the same with the 103.

spraying into the intake only goes to the combution chamber. The oil is kept seperate by the rings. No oil change necessary.

I love my 103. I figured I can hear a little motor motor noise just because the of fairing blocking wind noise. I did have the 2300-3000 rpm pinging, but a Cobra PowrFlo and Power Commander V eliminated that completely and seriously boosted power..
