Thunder heart ignition

[bdmridgeback]

ASM-5012 is correct, and easy install, and much performance increase.
About the same increase as the cam itself.

Really Jake, same increase as the cam?
Then my shit is messed up! I didn't notice much over the stock ignition.

This Blows!

Rob, I'm in the same boat as you as far as working on my bike, I had the Thunderheart ignition put on my 07 Mastiff and I could tell the difference, I recommend it

Is yours EFI? Mine is an 08 Mastiff with a 585 cam,XXX Modified Super G Carburetor, and Hooker Darkside Troublemaker Pipes. Would is be a worth while investment? What are the true benefits?

I have the super G carb, and the 600 cam, V&H big radius 2 into 2
