Re: 42 miles of He.....
Here is some of the work I did. The engine was broken in when this was done. It ran much better after this work. I think I am expecting to much in terms of engine noise. I wear a half helmet, and it scoops the sounds from the engine in ways that allow you to hear things in a more amplified way. If I turn my head the sound changes and is more tolerable.
I will keep working on it.
