Ignition Modules

Ignition Modules for Harley Davidson Sportsters

HAMMER PERFORMANCE offers quality ignition modules for carbureted Sportsters and Buells. The Dyna products are well proven, reliable, and attractively priced. They meet the needs of the majority of street performance engines. The Twin Tec products are full-featured and have more adjustments and more resolution. Programming kits are available for most modules, or you can use the preprogrammed curves and settings using the controls on the modules themselves.

Ignition Modules for Sportsters & Buells
12-Pin Ignition Modules
Note: 12-Pin modules were stock in 04-06 XL's.
Note 2: The Dyna 2000 TC-3 will work in 2006 models, however the speedometer & odometer will be off with no way to correct it. Speedo/odo correction can be accomplished with the DTT TC88A using the programming kit available below.
Nose Cone Ignition Modules
Note: Nose cone modules were stock in 98-03 XL's. However, they can be installed in any 1986-2003 model. Wiring is required with all of the nose cone ignitions we offer, none are plug-and-play.

Use high Hg versions to reduce
detonation on high compression

Spark Plugs

Denso Iridium Spark Plugs IXU24 for Harley Davidson Sportsters

The stock 6R12 spark plugs are generally too hot for a high performance engine build, which puts your pistons at risk of detonation damage. To keep your engine kit safe, change to a colder spark plug.

The HD 10R12X Gold is a high quality, long life spark plug with a special electrode design that resists fouling. This plug was original equipment in XR1200 models and is two steps colder than the factory 6R12.

The Denso Iridium IXU24 is a high quality plug with a tiny .4mm electrode to fire in even the most extreme conditions, and the iridium material resists temperatures as high as 4000 degrees F. This plug is one step colder than the factory 6R12.

Note 1: the plugs offered here all have 12 x 1.25mm threads, for all Twin Cam and Evolution Sportster applications.
Note 2: ALWAYS make sure you put anti-seize on the threads before inserting a spark plug into an aluminum head! The 10R12X comes out of the box with anti-seize already on it, good for the first time you install the plug only. Apply some more on every installation thereafter. The IXU24 does not already have anti-seize on it, so apply some before the first installation and every time thereafter.

HD 10R12X Gold Spark Plugs - $6.95 (sold each)
Denso Iridium IXU24 Spark Plugs - $10.95 (sold each) Out of Stock
Spark Plug Index Washers - $24.95/package
Five each of three different thicknesses

Timing Rotors

Machined Steel Timing Cup Rotor for Harley Davidson Sportsters

The stock stamped steel timing rotor in a carbureted Evolution XL is unfortunately a high failure item in a performance motor. The hubs like to fracture and separate and this has left many riders stranded by the side of the road. Head off this problem with one of our CNC machined steel timing rotors. These won't break and leave you stranded!
