I have a 2006 YZ450f and am looking some feedback from anyone who has any experience with this brand ignition. Results and reliability. It is a lot like the Vortex X10 ignition with 10 presets and is capable of doing your own custom programming. Sounds pretty good and is some what more affordable for me. I hear good things about the results from this type mod and the capability of adjusting on the fly based on track conditions. http://www.msdpowersports.com/Products/Motorcycle/Motocross/4218---Programmable-CDI-for-2006-09-Yamaha-YZ450F/ Thanks.
