Hi fellow R1s rider, just to know what actually is a advancer? what it actually help when you change it?

Im riding a 2001 R1 with minor modifications like K&N filter and FACTORY jettings.:cool:

the device itself is called an ignition trigger.

what it does is that it retards or advance the firing event of the coils according to crank rotations.

there are fixed and adjustable ones on the market.

And for us not mechanics that accomplishes what???? What does it do or help in non-technical terms????:iamwithst

er...it start hte ignition point earlier/later in the combustion chamber?

earlier/later depends on what setup you"re running;nitrous would need 0 degree or retard,high-compression motors would need advance,etc)

on a motor with stock compression,an aftermarket trigger may correct manufacturing differences between 15000 triggers made by the same dye.(spchk)they are basically more precise doing their jobs.

on a motor with high-compression(read modified)the combustion process(read: time it take for one charge to burn completely before the next cycle)is slower,so if you keep the same trigger point for the spark plugs to ignite,some of the fuel will go out of the exhaust unburned;"advancing" that trigger point will start the ignition cycle earlier,thus giving time for the charge to burn more completely giving more hp.

...or something like that....lol
