I am currently shopping for a tachometer for my 2005 Fat Boy. The tach manufactures state different things for single fire ignitions and dual fire ignitions. What do I have? Its a 2005 FLSTFI Fuel Injected Anniversary Fat Boy with the Factory 95 inch upgrade. Please help so I can get the right tach.

Thanks.

 

Dual fire is default firing.

 

Great, that was fast.
Thanks.

 

No problem. A buddy went with a single fire setup on his carb'd 1999 FXST.
Schools of thought on both. Snake oil vs. best thing since sliced bread.

 

I got this one from J&P and didn't require an adapter that the description says is needed for single fire.

NOT ON A TWIN CAM.

Evo's yes, but Twin Cams utilize single fire ignition straight from the Factory.

 

Thanks for catching that Stiggy. I had tunnel vision thinking about EVOs.

 

No problem!

 

OK, so lets be clear.... I need a tach that is EITHER for a single fire ignition OR has and adapter to convert a dual fire tach to a single fire? Is this correct???

Scroll down and they list the differences between the EVO and TC.
