Hey Fellas, I am looking to POSSIBLY swap out my CDI, I think mine may be bad. I see the Vortex being used, but does anyone have anything on FMF's AOF ignition? They are on sale @ www.fmfracing.com for ~$220.00, normally $500.00. Since I went to YZ timing (exhaust valve), I was wondering if I should go w/ the YZ400 ignition or the WR ignition? I e-mailed FMF Tech twice w/ zero response. Any ideas on this matter as well? Thanks Guys!! Kevin BTW, I DID race MX for many years, AMA Dist 23 (MN) 'A' Class - 250/Open, AMA Dist 6 (Eastern PA)'A' Class - Veteran and Ocala, FL once. I had to quit because I was beating the crap out of my knees!
