I'm still somewhat indifferent about my 2.5 duke, but I want to take care of it until I decide which direction I want to go.
I did a basic tune-up about 4 months ago and she was running a lot better.
Rebuild the 700 throttle body.
New plugs and wires.
Replaced the timing gear cover gasket
Replaced the harmonic balancer seal and did the repair sleeve.
New belt and tensioner pulley. (the tensioner lines are lined right up to where they should be)
Now I've noticed that when you have the engine under load, it makes a sound sort of like what you would hear from a diesel engine head.
Is that pinging or just lifter clatter?
