    Alligment problem / bad handling

    I noticed my z900 is not going perfectly strait. When it is on lower speed on Neutral approaching the intersection& when taking my hands off handlebar then my bike is pulling to the right. Have to balance my body to the left to keep the ride strait. I did a wheel alligment using a string method. I found out the rear wheel was off center about 1in/2.54cm. The string method is not really accurate but helped to improve a little. I decided to give my z900 to the dealer to check this out. My bike is only 5 months old & still under warranty. They did the alligment service & I went back to the previous a bad handling condition. The service manager told me that they did the best and is nothing to improve it. I  recently tried 2 bikes GSX750s and those going perfectly strait. The question is if you have the same experience. Maybe it is a special Kawasaki irreparable issue. What is your experience? Appreciate any advices.

    String Method is perfect if you use it correctly (strings just touching front part of the rear tyre). On the front wheel, measure from the rim, not tyre and be sure that measurements on both front and rear part on the same side of wheel are identical (that proves that front wheel is pointing straight). Compare left and right side, you should have same distance from rim to the strings, if not, adjust rear wheel alignment until you do.

    Yes, rear wheel do seems to be offset when you look from behind when bike is on padock stand (same as my Z750 did), but, alignment to the front wheel is what is important. That could be your 1inch/2.54mm offset you refering to - it is normal.

    On both Z750 and Z900 i had to tense left side of the rear wheel about 0,5mm more compared to swingarm markings to be aligned to the front wheel. That is not much, but did make a difference.
    Both bikes goes straight when no hands on handlebars after alignment (when there is no side wind and road without camber)

    Are you sure you sitting in the middle? Strange question, but i did see some people sitting offset.

    Google “ why does my motorcycle pull to one side” motorcyclehabits.com I think it is, has a good article explaining different scenarios that could cause this issue. Hope it helps.

    This seems to be well liked and accurate enough for most scenarios:

    The string method worked out. The chain alligment device didn't do right work unfortunately. When no hands on handlebar the bike is still pulling but is just a little. I'd love to have it perfectly going, but it is much better than after authorized dealer service done :( What I see now is much more knowledgeable peoples on the forum. Thank you all for sharing yours experience.

    How much of a mismatch do you now have in with the chain alignment graduations?
    Tighten it 'til it strips then back it off half a turn.

    Are you taking into account the crowning of the road for drainage? Your post reminds me of an old joke: The patient says, "Doctor, it hurts when I do this." "Then don't do that!"

    It's a feature. The heavy muffler can is a part of the problem.

    The oryginal heavier exhaust could be the case. Did you exchanged yours?

    finally yes. arrow gp2 but needs do my wheels re-alignment after a chain adjustment. the string method is taking a time. the chain alignment  is not do a good work. When I'm seeing my friend on his suzuki approaching the intersection without hands on handlebars I'm suprised why I cant do the same on z900..
