    gp1200r timing advance key

    ok so ive heard you can buy some type of timing advance key for gp1200's . So what is it how does it work and wouldnt this affect acceleration from idle because the timing is too far advanced or is the timing on a stock cdi unit not advanced enough and this key just brings it to a better potential someone help ?

    offset timing keyway moves the flywheel to advance the timing

    gives it better acceleration and a few rpms on top end

    I have them in stock

    Of course the ignition system is going to be better if you have the coin. I agree with upgraded, great bang for the buck. Have to be carefull with the advance and compression together tho.

    I always run 92-93 octane fuel with the keyway

    and if the carbs havent been re-jetted, then its a good time to go thru them... stock jetting is lean with stock motor anyways

    ok why is that? could it cause bad detonation if you dont know what you are doing ? and where do you reckon the best place would be to get one from? or do you rekon unless im prepared to modify more bits and pieces to my ski than there is no point and i should just buy the keyway instead ? and 93 octane is low octane in aus i usually run 98 octane is that bad for my ski cause i thought the higher the octane the better since im running more compression with the riva heads

    93 Octane USA is just about 98 Octane in Australia. They use the AKI (RON+MON) standard as opposed to RON for us. I only run 98 Octane on my skis, only because I'm running around 155 comp.

    how much do they advance the timing and what is required for installation? do you have to cut a slot out of the crank or are they made to just slip in and away you go ?
