Sounds…
« on: August 06, 2019, 10:06:26 am »
Okay, I may be just a worry-wart and I don’t have enough miles on my new-to-me C10 to know what “normal” sounds like, but – in the 3000-3600 RPM range I have a (it sounds to me) slight chain rattle/noise (like a lose chain may make when not under load) on the overrun just o the edge of my hearing, apparently down in the Tupperware on the left side… I don’t hear it, or at least not as much when on the throttle, but when trying to hold a steady 60mph or so going downhill there is a slight sound niggling at me…

The bike has about 51K on it – approx. when do the cam-chain adjusters became a factor (or run out of adjustment).  The Vulcans had a similar adjuster (a mechanically noisy engine), but on them there was a little aftermarket gizmo we got to slide over the end of the adjuster and give another .2” travel or so… anyway, no grinding oe anything like that -- and I am not sure why a cam-chain should care whether the engin is under load, but that's the best I can explain...

Am not at all sure that is what (I think) I hear – but that’s the closest I can describe – running at 65mph and up it is not apparent (stock exhaust).  Otherwise a sweet bike – has the nose dive so forks will be a project eventually, but rode about 100 miles in the rain yesterday and I don’t think I’ve ever been on a more firmly planted bike – lot to learn about it yet – one thing at a time…

Anyway, any advice – cautions or thoughts would be great…

Thanks…

I bought my 06 / 18k miles last year.
I thought the engine was noisy... so.....
I posed the same concern on here.
 I got several responses from saying " just the nature of the beast, but check the valve clearance"

So,  I went to the national rally last month,  and listened to some other C10s.
Some were a little noisier than mine, but all in all it just seems the nature of the beast....
  I felt much better about it.

A valve clearnance check is on the winter maintenance plan..... just to be on the safe side.

Super -- thanks... mine certainly doesn't sound like it is any distress, so I expect that is the answer -- My Nomad was a mechanically noisy critter (compared to the Evo HD I had at the same time), but ran over 100K, so maybe that is the nature of Kawasaki in general...

Same noise on mine, from info on this site I felt it was normal cam chain noise, some say the manual chain tensioners are a bit quieter.

One forum member described it a while back as a "box of rocks."  :)

In my case a small box of pebbles... but I didn't know what I was hearing...

Thanks all...

The camchain tensioner uses a ratchet mechanism. Over time it gets noisier and noisier until one day it ratchets forward and goes DEAD QUIET and you s*** yourself thinking it's going to explode. 😨😁😎

What do you do when it gets dead quiet? Replace?

I think he meant it goes quiet after it finally clicks to the next notch on the adjuster.

don't scare the guy... it'll be another 20k miles before it comes back.. and I've never seen an OEM tensioner run out of "travel"... if he has 50k on it, he's good for a lonnnnnng time. :motonoises:
