    The flywheel is mounted on a taper on the end of the crank. I take it you have removed the securing bolt or nut on the end of the crank?

    The tool you are after is a special puller. It looks like a cross, made of heavy rod, with threaded ends of different sizes for different engines. The one in the first picture is 07733-020001, it's a generic honda flywheel puller for heaps of models. (check your part number, you seem to have too many digits)

    You can make one with a large bolt threaded to the same size as the fitting on your flywheel, like in the other pic 3. You will need to bevel the threaded end a little.


    Don't have a big bolt?
    In that case you can try positioning two tyre levers or big screwdrivers under the edge of the flywheel and levering it out, evenly, while using your third hand to give the flywheel a couple of solid taps with a softface hammer.

    Be very careful doing this, as you will be levering against the soft cast Ali of your engine case with hard steel tools.

    You may need someone to give you the extra hand.

    Just do what I do. Rock into your local Honda servicing shop, and ask to borrow their flywheel puller overnight. Pickup at the end of the day, drop off first thing in the morning. no skin off their nose, and they won't have a problem if they are good guys.

    If required mention something about getting some new riding gears soon or something to indicate that if they help you, you will be more inclined to spend a bit of cash at their store.

    From memory your rear axle will wind into you flywheel........screw it in and tweek it with a spanner, give the head of the axle a "tap" to shock the flywheel free........or borrow the proper tool.


    Its harder to lose weight than gain horsepower.

    My Haynes manual for the RS suggests using the proper tool; which is unusual, as normally they give you a sneaky way to get around using special tools (e.g. clutch removal, you can get around it by refitting a couple of springs and locking the crankshaft).

    I'll have to pull mine off at some point, so I'll be interested to see how to do this.
