Have a chance to buy a vortex ignition for my 06 yz450f for a good deal. I have researched it a lil bit but want to know if anyone on here is by chance running one? What are your thoughts? Also the guy selling it doesn't sound like he knows to much about it. It does not come with a handle bar switch, do the older vortex ignitions not come with a switch? It's for a 06-09 yz450f but the seller is saying that it has mapping for an 09? He says he is not the one that installed it but it was on an intermidiate mx'r. He does not know if any of the maps have been modified or changed. If I could pick it up for 200 would it be worth it????
