06 883>1225 17k miles, @60,65 mph when i accellerate to pass i hear some top end strange intermittent tapping, only during accellerating, after reaching 70,75 it goes away? any ideas. Is there a top end service at this milage, i always hear tapping but was told thats a sporty:33:
 
You need to identify if the sound is combustion engine knock. You did not say what fuel/octane you are running. You may want to increase your octane on a tank load to an "over the top" value just to see if the sound goes away thereby indicating it was in-fact engine knock.

Once you identify what the sound is & where it is coming from, you can fix it.
 
DZ I would also check the exhaust manifold and any other exhaust pieces for a leak. Also check your plug wires, look for any signs of arching. Hope this helps and good luck on finding your problem. :cheers
