    Is there an easy way to check the steering head bearings? (without disassembling the bike)

    Whether you employ ball or taper bearings the first sign that your
    steering head bearings are loose will be felt through the bars as a
    pronounce clunk during hard braking...

     

    Then again if your steering head bearings are too tight the bike will
    weave and not seek it own center...

     

    To achieve perfect torque first raise the front wheel off the
    ground... next tighten the steering head bearings until the bars
    lock... and finally back off the nut until the bars free wheel with a
    slight drag... with this method you find that sweat spot and avoid
    over tightening and under tightening even if you upgrade to taper
    roller bearings...

    I put the tire on already, I can weight both and start a new thread. With the Aussie convert kit it's just mechanical bolt on of bits, nothing too technical. This is a 6" Duc wheel, so a 190 tire.

     

     

     

    Mike... Mr.RC45's 6" Marchesini is shod with a 180/55... the difference is illustrate in the drawing...

  3. Your removal would be much easier after a long ride when all the parts are at operating temps...

    Your axle is probably frozen at the wheel bearings due to corrosion
    from either rain riding or washing your bike with a garden hose... if
    the rubber hammer fails then you need more force like a large steel
    hammer... to protect the axle and threads source a hard wood block or
    plastic... installed the nut backwards so the flange faces you...
    strike the wood / plastic against the nut... the force to budge the
    axle maybe extreme so be prepared for the bike to move about... also
    be prepared for the axle to propel free in a shot... having a second
    body helps to control the reaction to the hammer force... after the
    axle is out check to make sure the wheel bearings are still seated in
    their place... a little grease will prevent this from happening
    again...

  4.  Motorcycle horns in good working order have a distinctive sound
    all there own... when people here that little beep beep... they have
    been trained over the years to think motorcycle... but if you replace
    the beep beep with a car... truck or train horn... guess what???
    confused people will charge right into your path thinking a car... truck
    or train has blown it's horn for them to get out their way... It's only
    natural for cagers to equate sounds to the first thing that pops into
    their heads in a panic situation...
    Like when you hear beep beep you think Road Runner... not Wiley E
    Coyote...

  5. I installed a Yamaha R1 Rec/Reg instead of the uniquely RC45 high
    dollar Rec/Reg... this was after I went through 2 stock R/Rs at $227
    each and 1 $300 stator and still I suffered the problem of low volts
    to the point where the engine would hesitate and quit... only after I
    give up on Honda's stuff and tried Yamaha's stuff did I have the joy
    of finishing my ride...

     After reassembly the yellow stator wires get really hot .

     

    Really hot is a wildly subjective term on the human scale... it would help if we had some C or F numbers to judge by...

  7. We are in the age of the Electronic Bike... fuel delivery and spark
    timing and instruments and everything else operate within millionths
    of a volt (milli-volts) and for some reason a component doesn't
    receive its allotted share of volts the system starts to prioritized
    which components are powered and which components are cut so you can
    ultimately return home...


    Trouble Shooting begins with the battery for it's the weakest link in the whole

    system... To determine the condition of an Maintenance Free battery give it a
    refreshing charge... wait 30 minutes... measure terminal voltage...

    12.8 or higher is a good battery...
    12.0 to 12.8 is a insufficient charge... recharge...
    12.0 or lower... battery unserviceable...

     

    Hard to start problems is mostly a problem of not enough fuel is being sucked into the combustion chamber...

    Generic things to check for that would effect cold starting are:

    1) enriching cable adjustment if you have one... too loose or too tight effects range...

    2) unobstructed idle air tubes... pinched rubber tubes from the air box restrict
    idle air... the result is a lean mixture that doesn't support 100% combustion...

    3) throttle body butterflies are 100% closed... any air that bleeds past the
    butterflies kills vacuum needed to draw in the correct rate of fuel... the result
    is a lean mixture that doesn't support combustion...

     

    Download a PDF file of an offical VFR Honda shop manual...

     

  8. To troubleshoot an internal noise the first step is to establish the
    rate at which it occurs... is the noise in time with the camshaft or
    crankshaft??? camshafts rotate 1/2 the speed of the crankshaft...
    possible source of camshaft speed noises are shim and bucket
    clearances... loose cam bearing blocks... broken valve springs...
    possible source of crankshaft speed noises are a scuffed piston...
    stuck piston ring... rod bearings...

     

    To pin point the exact location of the noise hold a long tip screw driver or a
    length of garden hose up to your ear and probe the suspected area...

  9. It goes without saying add fresh oil and filter but then activate the
    kill switch and then hit the starter until the red low oil pressure
    light extinguishes... this will ensure fresh oil flows between the
    crankshaft and journals... this action is prudent in order to prevent
    any metal to metal wear on start up... because after 4 years the risk
    is that the oil separating these critical parts is inadequate...

    A blocked breather on these bikes can mean not being able to open the fuel cap, AND enough vacuum can build up to severely deform and damage the tank.

     

    Like Grum said: Make sure the tank vent is clear and remains open or the fuel pump
    will create enough vacuum to collapse the tank... I've witnessed a
    Honda tank collapse because the dealer installed a California tank on
    a 49 state bike and the cap wasn't vented like this Ducati example...

  11. Always begin with the battery for it's the weakest link in the whole system... To determine the condition of an Maintenance Free battery give it a
    refreshing charge... wait 30 minutes... measure terminal voltage...

     

    12.8 or higher is a good battery...
    12.0 to 12.8 is a insufficient charge... recharge...
    12.0 or lower... battery unserviceable...

     

    The key to understanding a motorcycle charging system is RPMs... below
    5000 and the bike consumes more than the system can replenish... above
    5000 and the battery stores more than the system can use...

     

    We are in the age of the Electronic Bike... fuel delivery and spark
    timing and instruments and everything else operate within millionths
    of a volt (milli-volts) and for some reason a component doesn't

  12. The main difference between a 180/55 and a 190/50 is profile and
    diameter... the 180 is bigger in diameter and sharper in profile...
    the change in geometry is as follows... going from a 190 to a 180
    means rake is steepen and trail is shorten which lowers the steering
    effort... whereas going from a 180 to a 190 means rake is extended and
    trail is added which adds to the steering effort...

     

    Diameter...

    190/50/17=24.480 621mm

    180/55/17=24.795 629mm

  13. If you wish high mileage clutch life then you have to invest in some
    good old sweat equity... because at the first sign of slip it doesn't
    automatically mean your clutch is tired and worn out or that your
    clutch plates are wore too thin because you can Mic them to
    determine serviceability and within the factory specifications...

    Under scrutiny you'll find that your slip was due to normal
    glazing and contaminates...

     

    Deglazing clutch plates ain't nothing new... no sir... back in the 70s
    it use to be part of every savvy rider's maintenance plan... and for
    some reason that all change during the 90s...

     

    Inspect the friction plates for glazing... make sure you have plenty
    of material to work with... your shop manual states clutch thickness
    in thousands of an inch or mm...

     

    First removed the contaminants with Acetone... pick a hard surface to lay
    over a 600 grit black dry emery paper... rotate the clutch plate in a
    circle... you're just busting the glaze... don't get carried away
    remove too much material... You should end up with a friction plate
    looks dull like a new one as opposed to a shinny glazed one... recheck
    thickness...

    Next check the pressure plates for bluing caused by localized heat...
    make sure they are not warped... consult the manual for a thickness
    range... now removed the contaminants with Acetone and wire wheeled
    them to erased the blue and also to generally scuff up the surface...
    you should end up with a dull surface free of Blue marks...

    Bike on its side is a simple way to shift the oil level to an angle in order to remove the clutch cover without spillage...
    Have a new gasket standing by...

  15. I've been using Lithium Iron batteries since 2009... First was the
    (SpeedCell) since sold to a customer... currently Mr.RC45 is powered
    by a Shoria... I think days of the old heavy lead acid battery are
    number... smart money is on the new light weight Lithium Iron
    battery...
