In summary, my concern was unfounded and the service dept learned something about modern, air-cooled motors. What I don't understand is when they first contacted Honda, it wasn't identified as being normal. But now that I've heard the same rattling noise coming from three bikes all at the same time, I feel more at ease with getting back to "riding like I stole it".

I hope my experience can help others avoid what I've gone through. Now it's time to ride!


Geezalou... I sure don't hear a rattle in mine..not that I notice anyway. On a good note, you got your bike back, your fears have been calmed, and you can now ride with peace of mind.

I'd say there is no bad news.

One contributing factor might have to do with the fact that some of us are far more sensitive to different sound/noises than others. I drive my wife crazy whenever we are in a vehicle together because without fail I notice all kinds of rattles, squeaks and other noises that she doesn't. That kind of stuff drives me nuts if I'm unable to find the source of the noise.

When it comes to guitars or stereo equipment, I'm a total pain in the butt with my pickiness. I can sympathize with jodyz when it comes to a bike like the CB. Sure, the engine is sewing machine smooth, but my ears hear a symphony of various mechanical noises instead of simply a fantastically engineered motor. We each have to live within our own reality — for better or worse. Cool

My last bike was a modified H-D with high lift cams. This thing sounds like a Singer sewing machine to me.Cool

I'm happy for you, however the oil 10w30 honda sh puts this engine is too thin on my bike will put the 15w40 or 10W50 which is more dense and helps to reduce the interior noise of the engine.

Not going to tell you what to do with your bike because ultimately in the end it is yours after all, but it never ceases to amaze me that people think they know better than the engineers that designed the engine what oil is better for it.
In extreme cases like Phoenix in july, then yeah, I can see using a thicker oil, but in a normal climate I just can't concur.


RE: Engine trouble... awaiting diagnosis - Deanohh_imp - 06-27-2013

To me there's no point in trying to reduce engine noise by using thicker oil. With the number of moving parts in there, you're going to hear them. I like hearing them as the song of a well running engine. Ever hear a built mill in a car? a lot of clickety clacks but it goes like hell.

I'm more than willing to trade some engine noises for an oil that flows and circulates freely, doing its job of lubricating AND COOLING.


RE: Engine trouble... awaiting diagnosis - jodyz_imp - 06-27-2013

I keep forgetting to check with my service dept about what oil was put in at the 600 mile service. Summer temps here average 95+, with plenty of 100+ days.
