I have a 07 Heritage with close to 42k miles. It is stock except for Rush mufflers with 1.75" baffles and SEST. My tuning is close to stock except for the absence of deccel enleanment and slightly richer mix throughout. I run Amsoil in all 3. My engine runs much cooler than it did the first 3 years.
Lately I have noticed a loud tapping noise when I am rapidly backing off of the throttle. It only happens when the engine is well warmed up and I have been riding at extended high speed, around 55 or so. When I pull in the clutch and release the throttle to shift I hear it. I can pull in the clutch and rev the engine and the noise appears when releasing the throttle rapidly. It also happens if I am up to 65 and just release the throttle with the clutch engaged.
It sounds like four or five loud taps as engine rpm DECREASES coming from the top of the engine, possibly the front. The dealer thought it was the cam chain tensioners so they changed inner and outer. (~800 bones!). The noise was gone for a while and I thought that they had it but it started coming back around 500 miles later. Put an oil gauge on and my oil pressure stays up around 40 at highway speeds and never lower than 12 at idle.
After I have been riding in town or close to home at lower speeds it goes away. I can't reproduce it in my garage by revving up and releasing the throttle.
Any ideas?
Thanks,
Tom
