advanced ignition timing with coil help

[theconister]

hi im after a performance coil for 12volt system with 2 pin that would onley make the spark stronger i dont want one that increase the igniton timing becaust iv already got a cdi that does that and i know with some these performance coils it increase the ignition timing and makes strong spark but dont want to increase ignition timing any more as my cdi has alread done that so it there any that just makes the spark stronger ? any links will help thanks

because i need one that will just make the spark better as i have a cdi that already increase the ignition timing and dont want a coil that increase the ignition timing because with the cdi and the coil on the bike both increasing the ignition timing it will increase it too much and run poor

iv looked on ebay but cant tell if they onley make spark stronger or if they do both and advance the ignition timing aswell ?
