I have hc pistons and am running premium gas in my 03 Roas Star with the Dyna 3000 at a setting of 30B. I thought I was getting the Road Star Knock but the dealership mechanic says I have some pinging and recommended I use some octane booster. I am a bit skeptical but will go with his comments.

Before I jump into the octane booster, I thought I would try to make a couple of other changes.

First, I am focusing on retarding the Dyna 300 setting. To do that, should I be going to 28B or 32B?

Second, I have the bike set pretty lean - 67.5 main, 4th clip from the point on the needle with donut and 1 washer below, Mixmax screw about 2 turns out, enrichener screw turned all the way in, with BAK and Roadhouse Classics. I am going to move to the 3rd clip on the needle with 2 washers to get to about a 3 1/2 position.

Are these steps going in the right direction to eliminate the pinging?<br><br>Post edited by: RSMGreg, at: 2005/08/26 15:53
