I love it when someone posts, gets us answering, throwing out suggestions fighting amongst ourselves and never returns.

The management here invents these one post characters to up the post count.
In turn, this invites more advertisers, intern, this place charges more money.
I guess there might not be anything wrong with it..perhaps a little devious.

Harley identifies the cam sensor as a CPS and the crank sensor as a CKS. Max is accurate.
That said, I never knew that it was the piston that fired. I guess the front cylinder is not firing?

As mentioned the part is the CKS. Also another thing to note would be that if CKS had issues both cylinders would likely have issues. The safe method for firing cylinders on an HD is to fire the front if there is a doubt as to which cylinder on the compression stoke.. Firing front cylinder on rear cylinder timing would be the same as advancing the timing 45 degrees.

I hate it when pistons don’t fire.

Sorry, Not trying to be a smart as but it sounds like the spark didn't follow the wire, it stayed with the same location on the coil.

Add:
Don't know what bike you have so don't know is the wires are different or not.
I assumed the that bike wasn't single fire.

Thanks for all the info. I'll try switching the wires at the coil. Then switching the injectors. I'll post results

On a tc you can't switch the wires at the coil unless you switch the primary wires. The coil is single fire (2 separate coils).

Why all the talk about spark. I thought the initial post by the OP said he had spark. I’m confused.
