I had the 510 S&S kit installed in my twin cam 88 2002 Deuce with 30000 miles a couple of months ago. I also have a 07 Ultra. I like the performance of the cams but I hate the noise. It is fine when cold but once it is warmed up it sounds like a diesel when at idol, have put on 2000 miles since the install. Took it back to the indy that did the install and he said he adjusted the push rods but it still sounds bad runs good but hate the sound. I am thinking of changing out the lifters to see if that helps. Has anyone else had this problem.

 

I put the same cams in my 00EGC, cut the push rods. I don't notice any noise in mine cold or hot.

 

I went thru the same thing with my 26G's. I tried adjusting pushrods this way and that way, changing lifters, and adding a Baisley spring. Nothing quietened down the noise.....That was about 5 years ago. It's still noisy, but doesn't bother me anymore.
