Front cyclinder

[Herbert L. Williams]

Hey guys need a little help. My front cylinder quick firing out of the blue. I have changed plugs, cleaned wires and connectors. I am looking at replacing the coil. What coil do you recommend as a replacement. I ride a 2007 mastiff with 117ci S&S motor.

This is the one I am thinking about

Don't know if that's an exact fit.
Personally I go with one from Wild Steed worx

The vfactor unit is only a few dollars more and Curtis will back up that is fits the Big dogs -- just watch some coils are NOT for use with EFI if you have it.

Thanks, I will go with that.

You can switch wires around to make sure it's the coil. Thought i had a bad coil once on my AIH. Turned out to be ignition module. There should be a troubleshooting guide here somewhere particular to BDM...

Good recommendation, ChoppaNoob...one time my front cylinder quit firing, and the problem was that the dang wire had pulled out of back of the coil. Not enough to to fall out, but enough to lose connection. Had to look pretty carefully to see it. As I recall Blacktopper pushed it back in with a stick. Cheapest and easiest fix ever!

I'd check the coil wires real careful. One is not making good contact...

I have 2 red lights on, when the bike is starting and running on the rear cyclinder, I see blue and yellow flashing as well. The bike will not stay running and the front cylinder still isn't firing, any suggestions
