I am developing a pretty good top end knock/rattle on my 17.2K mile '03 Deuce. Oil is 1 month old 2000 miles Mobil1 v-twin 20-50. I just put new quieter baffles on around a month ago, and I realize i may be hearing some things I didn't here before, but this has definitely become more pronounced over the last couple weeks, and I'll there's been some pretty rough high rpm and high speed riding involved in those couple weeks, but mine is far louder than most others I hear at that milage, and about as loud as a buddy's 50K mile Roadglide. I plan to change the oil again in a couple days, but what should I be planning in the near or far future as far as internal repairs? SE stage 3? S&amp\\;S 110 inch motor?

 

Is the motor stock ?? Have you checked your primary chain ?? If thats to loose it will sound like a knock... If its not that i would drop the pushrod covers and see if there is any play in the rods ...

 

You might want to also check your spark plugs, I had a loose one that sounded just like lifter noise chatter.

 

Its from all those wheelies in the parking lot.

Cant help you. My 04 deuce seems to be getting noisier too. I might be amagining things too.
&nbsp\\;
My motor seems to be shaking more these days. I might check out this winter.
&nbsp\\;
Hope you figure it out.

It ain't from wheelies. I'm sure it's from too many high rpm's.
