  • X5 -Gen. mt. XL’s

    Similar to our H5 Big Twin magneto, this fully automatic impulse-coupled unit slips into where the generator was. You will need to remove cam cover and replace generator idler gear with magneto drive gear. Some stock removal from a cast rib in the cases above bushing will be required. Due to it's impulse-coupler, unit puts out a killer spark, at retarded start timing, no matter how slow motor cranks. Fits all generator Sportsters, K models, and 45 Flatheads. (for big twins use h-5)
