hmm, the tappets, I don't know (I will stop by his workshop tomorrow) --- I can only feel it around 2200 rpm (on roads) -- also when the car is idle (at home) and I rev it up, I can clearly hear the noise @2200-2500 rpm. ---- it feels continuous around the rpm I mentioned, below 2000 I don't feel or maybe the noise is too low to be felt.
one gentleman (mechanic) @montgomery road told me that it's sound of crunk (I think he meant crankshaft) --- (I was like, Lo G band baj Gai) -- but I will visit this Honda mechanic to get the clear picture -- I always try to get valuable input from here b4 visiting the mechanic.
You think it's to do with tappet adjustment?
