    Go this Yamaha Parts Web Site:
    http://www.yamaha-motor.com/sport/parts/home.aspx

    Look closely at all the parts that are used to attach the Rear Wheel to the Final Drive.
    Match all the Parts in the drawing to what you have on your Bike.

    This could be a number of things. A missing Spacer. Parts out of order.
    The Wheel incompletely seated to the Drive Unit.

    You should take a photograph of the problem and Post it so we can get a good look at whats going on there.

    In the mean time. You go to the Yamaha Site. Plug-in your Bike and pull-up the schematic for that Rear Wheel.

    To throw in my 2 cents since you are new to shafts. The tire always runs close to the shaft even when the wheel is centered but close is a relative term. You should check the parts as Rick suggests to be sure your wheel is centered.

    I have owned a couple of shaft bikes - usually I get someone to hold a light above the shaft and look at the gap as I rotate the rear tire. Helps me see if it is rubbing or wobbling any.

    On my XJ the wheel is VERY close to the shaft but does not rub.

    This is the normal condition on my XJ650 as well as on my 84 V45 Magna (shaft drive as well). Not a problem unless for some reason you are inclined to want to put a larger wider tire on the rear rim, at which time you'll find this will be a problem.

    I've got huge tires on my Vmax and some sizes rub until they get clearance. We even have aftermarket wheels that shift the centerline over to the right more to allow for larger tires. This does make it off center but they ride ok. It's harder to lean to the right and easy to the left. Some get so large (my 1500 runs a 200/50/18 vs stock 150/90/15) that we have to notch the swingarm for more clearance.

    I think on my Turbo I ran one size over and could barely move a slip of paper between the tire and the swingarm.

    side note
    tires tend to change size!!
    They expand and contract with each revolution, temp, torque changes.
    And when you lean is when they will rub most

    edit- I happen to run a 130 on my seca's rear, 120 is stock. Have no issues yet, and I drag pegs EVERYDAY

    I think that's the size on the rear of my seca turbo. I have ran that size since I bought the bike back in 88 (of course it is just now being put back on the road since it sat since 94).
