I have an 02 EGC with 95" engine, 203 cams, Reinhardt true duals & 2007 SE mufflers (quiet!) & 45,000 miles. I use Amsoil lubricants.
One of the things I wanted checked out at the 45,000 service was a knocking that is loudest on start-up then quiets down, like a dry lifter (but, it's not). What is odd is that, as engine speed increases, the knocking continues at the same speed [i.e., does not increase in speed as engine speed increases], but it gets louder.
My mechanic does not want to do a blind tearing into my engine, nor do I. So, do any of you have an idea where I should look?
Any help is appreciated!

 

How can it not follow the engine speed or at least half engine speed? Sounds like piston slap, but don't rule out a noisy compensator too. Lots of things can make noise in these engines so a stethoscope will help you zero in on where it comes from the quickest. Check rocker areas, cylinders, front of primary for comp as well. Don't rule out the lifters or possibly of an inner cam bearing as well as cam chain tensioners.

Is the noise in neutral? Or, are you in gear and the bike is moving while it makes this noise. The only thing that wouldn't increase with engine revs would be from the tranny back... that might slowly increase with speed of the bike?

Let us know so we can all ponder this further...
