Re: 2007 VTEC with knock
Well, before I bought the bike, the previous owner took the bike to a dealer for a total inspection simply because it had sat so much during it's life. It passed with a clean bill of health.
2 days after I got it home we headed out on a nearly 1000 mile trip to some southern states, and half-way along on this trip is where I first heard it. It was very intermittent at that point. So when we got back home the FIRST thing I did was change the oil and filter. I used good Honda Pro GN4 per the manual, and a factory Honda filter. It made no difference. If anything, at this time the knock is much more consistent than it was, and at times very loud.....I am talking embarrassingly loud because I know others can hear it.
This isn't some VTEC normal noise, this is something wrong in the engine. I have done search after search after search on the web about this, and my problem just doesn't exist. The only thing I found is a claim that throttle bodies out of synch will cause a knock. This may be true, but the knock I hear sounds more severe and detrimental than some fueling issue could cause.
Love the bike though, I mean I absolutely adore this machine. I just don't want to have to spend a fortune to diagnose and fix this thing. I mean, I will obviously if I must, but on a 3100 mile machine should I really be having a problem like this?? I'd say not. This bike was hardly ridden during it's life, and it was garaged, covered, and the minimal service done by the previous owner (which amounts to the inspection I spoke of and 1 oil change) was always done by the local dealer, I called the dealer to verify this. It's a pristine bike and thus the reason I bought it. Like I said, since 2007 he only put 1900 miles on it.
