well i have a report.. i could not get the electrosport stator to run (no spark) with a stock cdi box. i did however get it to run with a procom cdi but not very well. i though it was a jetting problem for weeks chasing it around rich/lean and could not get it right. i finally bought a stock cdi and stator and now the bike runs perfect!! i am going to stay away from the aftermarket stuff....
