motor knocking----need serious opinion
Here is what I have. About a year and a half ago, I sold my 07 zx14 with 5k miles on it. Recently, I purchased another 07 with about the same amount of miles on it. Issue is once I got it home and cleaned up, I noticed a slight knocking from the bottom end which raises with RPM. The knocking is heard with the clutch held in to cancel out he clutch basket noise. The other 14 I sold had the exact some knocking sound and the dealer techs and some other folks told me it was normal.
A friend of mine had his one knock that way and the bearing soon went out.
How worried should I be? Note I also had a 06 zx14 which was my first zx14 and #3 bearing went out after 2 wks. 12k miles on it. I love Kawasaki and the 14 but how in the hell is my luck that bad!!!!
Any advice on a possible fix or what u think may be going on?

Well we can't hear your knock so it hard to tell if it is normal or not .. I can tell you both my 06 engines had knocks and so did Jesses 06 and we never had a problem .. My 09 has NO knock ..08 they changed the pistons for some reason , it may have been piston slap in the 06 and 07 bikes that caused Kawi to change the pistons and add padding to the inside of the valve cover ..I don't know what to tell you ..

Well I appreciate your response Smokin. I remembered you commented on my post from the knocking on the 06 I had. Since I posted, I found out the guy who I sold the other 07 two had the motor go out not too long after. Exact same knocking I'm hearing. Bottom end rod type knock that increases and slows with rpms. Its constant and sounds like it coming from one cylinder--not random also not a rambling sound like the clutch. I can hear it more on the left side of the bike. Took a stethescope and you can definitely hear a knocking when placed on the oil pan. Dont know if you ever did that with your 06 but sounds like a rod.
Must say i was skeptical about buying an 06-07. I knew a few people have had #3 bearing problems with them.

Stop riding it. Drop the sump pan see if you can see bearing debris. A knock is present with clutch in, left side lower sounds like... Says enough tear it down!

Wow think its time to start going back to church. I love Kaw but if this turns out to be the case, thats my last straw. Gonna have to convert to Zuk. I will drop the pan and check it out soon as I get a chance.

Smokin would you also say the knock on the lower left side with the clutch in sounds like a rod knock?

On the last rebuild on my 07 I installed the 08 pistons that had a different material. Quiet as a mouse now along with the Ape manual adjuster for the camchain. Almost 38k miles now and runs and sounds sweet. There is a hesitation at 3.5k rpms if full throttle is applied. Then is has another hesitation problem from 6k-11k rpms. It doesn't hesitate, feels like a pissed off 2 stroke that wants to wheelie at 5" extension on the arm.

LOL Had another 1k spin a rod bearing last Wednesday night at the track. That makes at least 2 that threw rods and another 2 or 3 that were caught in time in just the last 2 years.

I have a 2007 and it did that and ended up being a spun rod bearing. 3000 to fix and now it is showing signs of it again. when i start the bike after it has been off for a few hours it knocks real loud and then goes away after about 10 seconds. A couple of friends had the same problem with 07's haven't heard on any other years. my advice i would sell it fast. I have 3,000 in the motor and 2,000 in the transmission just keeping it running and i don't even race.

That knock on startup is just the cam chain tensioner, nothing to worry about really.

The high horse Busas run tight on the main tolerance and loose on the rods for oil. Don't have a knock problem because of the manual cam adjuster..

Thinking of getting rid of it since I haven;t even put 5 miles on it since i got it. sucks the way my luck works. no more 06-07 if I do another zx14 yet I love the bikes. 08 on up from now on. I joke about busas but everyone and their mom has one. i hate that.
maybe its a sign from above. Stay off bikes

Being that most 06-07 zx14s with motor issues are the big end of the #3 Connecting rod, has anyone figured out if oiling is the issue. To many having the same thing go out to not have a certified fix or certain issue. How much to stroke the damn thing 2mm? different pistons, worked crank, and new bearings?

A bud's got a 07' doing this (listen to video), is that a rod knock? He ran the engine w/o the clutch assembly to check, & it's still there....

That sounds awful. Sounds like a heavy knock, cam chain is lighter and more tinny.

Im going back to busa after I get mine back from the dealer.
I had the same thing happen with less than 2k miles.
When I talked to my dealer he said that Kawaski knows they have a problem and are sending new updated different parts to remedy the issue. I have buddy's whith 14s that race them and none have had issues other than bad cam chains and guides. But after visiting so many 14 sites and hearing all the bearing failure rates Id rather go slower and race all year that to keep rebulding. I love the way my 14 just runs off and leaves the busa but reading about this issue from 06 to the present is very disturbing to me. I hear the problem is so bad you need a Muzzy oil pump .
what scared me the most is some guy on another site said this and I qoute"
"tuningfoRk wrote:
Every single 14R motor I have had apart, the cam chains have looked that bad or worse. From 1800 miles to one with 9500 on it. Some slightly kinked, some with broken links. I have also seen terrible bearing wear in all of them. Mains and rods. Wrist pin gulling in the pistons and rod...Lots of issues. A couple things I have found that massively helps the bearings.
1, I put a restrictor in the case in the oil supply galley for the head. .120" hole in a 1/8 npt plug. A 1/8-27 npt tap will cut threads perfect in that galley with out drilling it first. Just make sure to run the tap deep enough to screw the plug in bellow the deck surface. This will help keep oil in the #5 main.
2, I remove the plug (stator squirter) in the end of the galley for #1 and 2 mains, then drill that galley to 11/32 (tap drill size for 1/8-27npt tap) CAREFULLY. The tap the end of galley for 1/8 npt plug. You will also notice the the supply galleys to all the main bearings are all different sizes...I have 3/8 tapered reamer that fits the biggest one (#3) perfect. I set it in the galley, mark the reamer for depth. And ream all the other to match.
I change the cam chain in my blower motor every 20-25 passes now...I am working on a roller chain conversion right now.
Since doing those oiling mods, with a Muzzy pump cover, HV gear, stock by pass valve shimmed. After warm up (130°) my bike idles at 140+ psi oil pressure and have not hurt a bearing in 180 passes. I tear down and inspect every 45-50 passes.
Hope this is useful.

what scare me is he said every one not some but every one.
good luck but Im going to go slow again and have some fun.

I am a lit.tle confused
You talk about your 2007 14 as having rod issues.
Then you post something from tuningfoRk that's talks about camchain and bearings issued with the 14R.
That seems to be two different engines and 2 separate problems. I had a zx11 which threw the #3 rod after 40000+ miles but it was MY fault. I ran it when i was low on oiI. I have a zx12 with 31000 miles with no problems. I learnt my lesson and always check the sight glass.
So ultimately you need to keep your oil ALWAYS topped off and to the top of the sight glass.
But that's just my 2 cents and won't fix you current problem.
