I thought this may happen, The compensator issue in this thread above was somebody elses issue. They addded on to my original thread. Having said that, I have never had a compensator issue at least as of yet. Mine is an '03 and believe that was pre comp nut issue. I do in fact have a Hayden in the primary. I couldn't classify this as anything but a knock. It is well beyond "tick". It is bad enough that if you put a stethoscope on anything, you can hear it. Probably including the rear tire. Even my wife came out of the house and said "that doesnt sound good". It is definitely heat related, I can let it sit for an hour, fire back up and once it starts up to temp. the noise comes back. Does the Bellville spring pack come from the dealer or another source? Thanks Dolt.
