Cam chain stretch?
« on: October 11, 2020, 04:14:37 PM »
Re done my bearings and pads with cyco pads. Getting a lot of noise from the cam area. Pretty quite 2,000 rpms and under. Really starts screaming like lifters but I can hear in the cam cover are with  my sethescope. I asked a HD tech and he said the chains will stretch. Any one have any input? only 3,000 miles since all new bearings and pads.

I don't know how much the roller chains stretch but those old silent type (99-06) stretch big time from personal experience.  Glad I went with conversion cams.

Hi Dresserdan,
Did you shim the sprockets so they line up well? That can cause some noise and itís worth addressing if you didnít.
Thanks

The noise didnt really start to get real bad until I had about 3,000 miles on it. It sounds just like all the lifters are bad when ever the motor gets over 2,000 RPM's. I put a Stethoscope on it and the cam cover is where the noise is coming from. I will get into it this winter and will go with the 07 set up.

I had a similar experience on my 05 RK with the hybrid set up. It turned out to be the secondary chain.  I replaced the original no name chain with a Morse branded one I found on E-bay, no more noise.
