Stock Ignition

[COVSpringer08]

Should the stock coil and wires but upgraded on 2007 FLHX 103 build? What plugs should be ran in this build? A 103 with Zipper's 575 cams

Thanks!

Actually the stock stuff will work best with the ION sensing coil and electronic ignition. You may want to try Buell 10R12 plugs with higher compression (10.5+). Just be sure everything is in like new condition.

I'm only looking at 10:2:1 so stock plugs also?

Stock plugs unless you're experiancing a lot of ping, or find yourself in really hot climates like Arizona. The 10R12's are less tolerant to fouling on cold starts.
