nope its set to one spot only non adjustable.
But you can make off set keys to change it, its a pain to do. look at the mag rotor the key way is
even not true to the hole on the mag rotor so the key is going to be ornery to make I tried one and only one so far, total flop
. I'll try it again though I went way to far on the advance on the first try.
I've also been tinkering with an adjustable mag coil bracket. to make that work you will have to do some serious cutting on the engines cover to swing the mag coil there just isn't any room to play
with on them.
I should learn to leave things alone and just ride it. but what fun is that?
I wonder if a guy could change the timing by use of some electrical components to alter the current to the cdi?
