    15,000 mile service

    I did the service today at 15,300 miles.

    Just a couple of 7500 mile service vs 15000 mile service photo's.

    7500 mile Intake #3 --- Very minor pitting this was the only problem on the 7500 mile service.



    15000 mile Intake #3 --- Full Blow Aids--- look at the comparison.



    New cam problems that didn't exist on the 7500 mile service. See pics below.
    Intake #4

    Exhaust #3

    Intake #2



    One more picture, if you stand far enough away they look perfect.

    Sorry to see the damage. What is your game plan now??Does anybody in the aftermarket make cams for ZED?? Do you get new factory cams?? Or do you listen to your wallet and say Fook It? I would be interested in view points. I am about to pop the top on my motor (7400 ish miles)

    Thanks for the input

    Do you have the extended warrenty?? Get your dealer on your side and go for new cams under warrenty.

    If not, do like others have, run 'em like they are. From what I've read they tend to go a long long way after developing full blown aids.

    Right now, I have the full extended warranty which expires on January 2010. I've only had the bike for 9 months and bought it new, I plan on racking up 100,000 before the warranty expires 20,000 a year X 5 years. What am I going to do? Ride the thing. I let Kawasaki know about the problem, they want pictures to send in for warranty approval. For the time being I don't really care, I'll just keep on riding until the thing blows up, then they can buy me a new one. I've done my part in letting them know about the problem.

    For those who don't know, I'm riding a 2004,..... ZZ-R1200 of course.

    And for inquiring minds.............

    This was the valve clearances at 7500 miles.

    3. 0.18mm
    4. 0.20mm
    5. 0.20mm
    6. 0.24mm (may need a 2.85mm valve shim next valve adjustment well see, currently has a 2.80mm shim).
    7. 0.20mm
    8. 0.20mm

    Intake Valve Check (standard 0.13~0.19mm)

    1. 0.13
    2. 0.15
    3. 0.18
    4. 0.15
    5. 0.18
    6. 0.13
    7. 0.15
    8. 0.10 ( changed from a 2.80 to a 2.75mm shim currently at 0.18)

    Carb sync and pilot adjust check.

    1. 1 ¾ turns
    2. 1 1/8

    One other comment, pitted cams can usually go another 60,000-80,000 miles+ and you won't notice any difference in performance. If you took apart 100 cars, trucks, bikes of all different makes and models 85%+ (from what I understand) would have some kind of pitting. Not something to lose any sleep over.

    I have just had my 12000km service done, and I have a similar result to yours at 7500mls. I also needed to have 3 shims replaced that were too tight.

    Some of the ZRX guys have installed ZX11 and ZZR cams into their bikes. I'm wondering if those are prone to pitting?


    Bill.

    I suffer from kleptomania. When it gets bad, I take something for it.

    My cams looked identical at 15,000 miles to the way they were at 8K. No change. No pitting.

    I'll probably check them again at 22K'ish just to see what's happening. Not too worried either way as I also have the extended warranty.

    I just wish I knew what that grinding noise is when I first take off from a stand still. The chain is fine, and when I kill the engine and coast I hear nothing, it's just when I'm engaging the engine and letting the clutch out that I hear it. The clutch holds just fine when sitting at a red light. Hmmmmm.

    Hey all,
    I'm still relatively new here. I'm seriously looking at getting a ZZR in the next month or 2 so I've been doing my homework.

    I keep hearing about the pitting of the cams. Is this common on the '05 as well?

    Also, is there any correlation discussions about different oils or oil change intervals in relation to the pitting cams?

    Thanks.

    Buckeye, welcome to the forum!
    Pitting only seems to appear after the first 7,500 miles and I've not heard any '05 owners make the complaint yet. Several members here have been riding with pitted cams and have no problems and the whole thing may in fact be blown out of proportion. If you are concerned about it, get an extended warranty but check around for the best price. I got an extended warranty for only $350 when the dealership was quoting me $800. You have until the 1 year factory runs out to get the extended one.

    There have been many discussions and debates on oil around here but everything I've read from members with pitted cams does not point to any specific trend in oil. Both conventional users and synthetic users have suffered the pitting so there seems to make little difference (except for how much you spend when you change your oil).

    Cam pitting in Kawasaki's is not new, if you check with the Concourse owners you'll find plenty of them that dealt with it for years. I believe some of the early ZX-11's had this same problem so maybe it's not a problem. Maybe their cam shafts just deteriorate over time and it's up to us to replace them when the time comes.

    I blame it on the "Thermodynamic Principle of Entropy".

    I got a bit lucky (so far ...). For the possible new ZZR buyer, I am a 2005 owner, new, and no pitting at 7,500. now I have 10K on her with no issues Very smooth bike, very little vibration (my hits at 4-4,500 rpms but its really minor) and so far runs buttery smooth. Engine Mods = Holeshots + carb adjustment, K&N filter. Also recommend Corbin seat, Givi screen and I forgot .... I did put on gel grips on, which help a bit but before I just didn't have much vibration on mine. Once Holeshots went on the 5-5000rpm vibes came down to 4-4500 (interesting, but literarly no exageration true). good luck.
