    You can buy a new / replacement one from Demon Tweaks, or if they still offer the service, QEP will lighten your current one. The latter option being much cheaper.

    What are the gains from this?

    The engine doesnt have to spin up so much weight. Lightning the fly will allow the engine to rev more freely.

    In a nut shell.

    Its all about inertia

    how much difference would fitting one make ? and a rough idea on price to have mine lightened ???

    Partly. There quite heavy.

    But as said, for the engine to rev more freely.

    To get it done your looking at around 100 notes.

    Ummm pass tbh! I done it in college ages ago. The moment of inertia is like weight going around in circles or something.

    The engine will accelerate (literally in RPM) more quicker, and of course, for all actions, there is an equal and opposite reaction. Therefore the engine will de-cellerate quicker, making it more responsive.

    They say a l and b flywheels make alot more different than an exhaust system.

    Best suited to boost applications.... apparently

    But yes, from what i've heard, worth the money.

    cheers for that info, told me somthink i didnt know

    looks like a lightened flywheels is the way forwards then

    will it affect the torqe ??

    People say that torque will be affected, and it's noticeable when going up hill. The Saxo / 106 flywheel in the grand scheme of things ins't that heavy anyway, so the gains will be small.

    Have you posted in the wrong thread mate?

    do they just skim the face of the flywheel to remove material?

    remove metal do qep.

    Ill try and dig out a pic of one done by them.

    just to comment on colins post, are you sure a lighter wheel will decelerate faster - less weight should mean that the wheel maintains momentum more and stays spinning, although it is proportional to where the weight is a guess

    It well definitely spin down faster mate.

    with more weight it will keep spinning longer, will it not have a higher centrafugal force with more weight? keeping it spinning longer?
