hiro Posted March 23, 2017 Report Share Posted March 23, 2017 Evaluating a bike for purchase. One thing I noticed was a high pitch metallic "tinking" at idle. Anything to be concerned about? (I've been reading about cam chain tensioners.) Sounds similar to this: https://soundcloud.com/heath-taylor-4/2007-ninja-650r-odd-metallic Also, should I get new tires immediately even if they have very low miles on them if they are 5-6 years old?

flashesbuck Posted March 23, 2017 Report Share Posted March 23, 2017 Hard to tell from the audio, I have a newer ninja 650, and it sound similar I would say. I wouldn't be to concerned about it.... Check valve clearance and ride on. Quote Link to comment Share on other sites More sharing options...
hiro Posted March 23, 2017 Author Report Share Posted March 23, 2017 The tinking is steady at warm idle, unlike in the video. Same sound though. But then, the bike does have an extended warranty. Quote Link to comment Share on other sites More sharing options...
Wandering Soul Posted March 23, 2017 Report Share Posted March 23, 2017 Don't know about noise issues, but google "tire date codes". Look on your sidewalls and see when they were made. More than two years old, replace them. Any cracks in the sidewalls, replace them. Quote Link to comment Share on other sites More sharing options...

The side walls look good. Tread is good. Rear is a little flattened in the middle at 1700 miles. Always kept in garage, so maybe that helps. I've felt the loss of traction of my car tires when they had a few years on them. Don't want that to be my only front tires losing grip!

Wandering Soul Posted March 24, 2017 Report Share Posted March 24, 2017 Tread life is squat, read up on tires dry rotting. What; $350 for new rubber? What's your hide worth? 1 Quote Link to comment Share on other sites More sharing options...

I replaced tires on my Ninja 300 much sooner because I didn't like the feel. I priced out a set for $227. The rear is only a 160-60-17.

whaler Posted March 24, 2017 Report Share Posted March 24, 2017 Kawasaki air injection uses reed valves and they tick at idle, its pretty common. The sound should go away as soon as you rev the bike. Cam chain rattle usually only makes a sound when coming off a rev when the chain unloads briefly. 1 Quote Link to comment Share on other sites More sharing options...
Killer_kaw Posted March 24, 2017 Report Share Posted March 24, 2017 I would defiantly replace tires with that much age on them. There's nothing like the feel of fresh tires anyhow. In my experience with Kawasaki inline motors a little noise at idle isn't a bad thing. When they get quite its most likely in desperate need of valve adjustment. Reed valves do have a tick at idle and if it bothers you can easily be blocked off. As mentioned by Whaler cam chain noise should come in to play after spooling it up and cutting the throttle. 1 Quote Link to comment Share on other sites More sharing options...

hiro Posted March 25, 2017 Author Report Share Posted March 25, 2017 Finally found what look like date codes. 4611 rear and 4811 front, so late November 2011. 5 1/3 years old. At least the front is 2 weeks newer?? Quote Link to comment Share on other sites More sharing options...
hiro Posted March 25, 2017 Author Report Share Posted March 25, 2017 This is interesting, but the road is not a track, of course. Test results: old tyres versus new tyres The tyre manufacturer METZELER has tested a set of motorcycle tyres aged five years and a brand new set of motorcycle tyres in racing conditions and has then compared the results. The five-year-old tyres had been stored properly. The old and the new sets of tyres were driven over a distance of 200 km and tested for 5 laps with the same motorcycle on the test run Vizola. The differences between the lap times between the old and new tyres were so minimal that there was no clear winner and that the quality difference could practically not be determined.[Source: METZELER technology seminar 2004] Quote Link to comment Share on other sites More sharing options...
Wandering Soul Posted March 25, 2017 Report Share Posted March 25, 2017 Lap times are secondary to the rate bones heal and skin grows back for my money. Rubber ages; over time it dries out, and will fail. But it's your bike and hide. 5 plus years will never be on my bikes. 1 Quote Link to comment Share on other sites More sharing options...
motocat12 Posted March 25, 2017 Report Share Posted March 25, 2017 That test was 5 year old/stock new un-heat cycled tires. Almost as good as new, better than old used. Different compounds would shelf age differently. When were zzr tires first mounted on the bike. Quote Link to comment Share on other sites More sharing options...
Fin Posted March 27, 2017 Report Share Posted March 27, 2017 The "tink" sound sounds like something is cracked or loose, not a valve clearance issue. At different vibration frequencies you'll notice different sounds. As for tires, personally, I never risk it. Tire pressure, tread, and fluids, three things I never take for granted. I've heard of too many people taking a high end or low end on a corner because they didn't check pressure and tread. And with Spring rain on built up oil and gravel from the Winter is a bitch on bad tires. Quote Link to comment Share on other sites More sharing options...
Fin Posted March 27, 2017 Report Share Posted March 27, 2017 (edited) Revzilla is running some deals on tires and shipping for what you'll be spending is free. I went from Metzeler to Shinko on my bike.

JustinNck1 Posted March 27, 2017 Report Share Posted March 27, 2017 If you get the bike, I would ride it with those tires and see how they feel. If they stick and feel great, try to get some miles out of them. I just wouldn't push them first time out. Quote Link to comment Share on other sites More sharing options...

JustinNck1 Posted March 27, 2017 Report Share Posted March 27, 2017 (edited) I wouldn't own a Shinko for any kind of riding above cruiser pace on pavement. Maybe for a dual sport or something of that nature. I've seen enough of their street tires to know their junk. Just to save 50 or 60 bucks? No thanks, I'll take a Bridgestone, Dunlop, Pirelli, or Michelin. I have also seen enough delaminating Metzlers to stay away.
