I ride an 03 anniversary lowrider, stock carbureted TC88, has about 65k on her. Suddenly developed a ticking or tapping noise that sounds like it's coming from the rear cylinder. Also at the same time the bike got louder and again it sounds like it's in the rear cylinder. It sounds as if someone had taken the baffle out of that pipe. That's the only way I can describe it. And also she's running like shit now. Does anyone have any ideas or suggestions or has experienced this before? I would really appreciate any input.

Check to see of pushrods are loose when at TDC.

If so, you may have a bad lifter roller bearing. Would cause same sound you describe.

Welcome from PA!

As stated above ... Lifters and, tensioners especially, have been a problem with the earlier twin cam motors.

"Rocker-Lockers" are a good add-on too.

Cheers,

If the tensioners were replaced 3 years ago the lifters should also have been replaced too. OP should check his receipts.

Rear exhaust gasket blew out maybe, problem matches the symptom.

Why should the lifters have been changed along with the chain tensioners? Never heard that one before. Am I missing something???
I just changed both exhaust seals yesterday. Sounds and runs the same.....

Standard procedure when servicing the cam chest and plate assembly. All parts that come in the service kit are supposed to be installed.
Now you've heard it !

That sounds like you got a different service kit than the ones I was getting. I was ordering the cam service install kits that didn't include the tensioners, they had to be purchased separate.
The cam install kits include everything: gaskets, lifters, bearings, gears, chains, etc., just no tensioners.
FYI, the MoCo made these kits available for warranty back in '99 - '00 when the cam bearings were failing.
