What would cause inconsistent spark?
I seem to have an inconsistent spark in the front cylinder.
I checked timing the other night and it was sparking and making the light work fine.
Tonight, it's making the timing light flash intermittently, and the miss I've been fighting goes along with the flash.
I have a new coil, wires, plugs, ignition. What else could it be?

Question....why are checking the timing every night , does it not run right, is it missing ?
If it runs okay just ride it.....I checked my timing once after the top end rebuild, set it and have been riding since....no problems.
If it is running okay then it could be your timing light that is the problem.

that's just it. It seems ok on the highway, but at low speeds, it still has this annoying miss. I know its not supposed to be there.

I'd also be checking all the grounds. As much as you wash your bike, you probably have corroded them to the point they are not making full contact...

Swap the plug wires and see if it moves. New plugs? Swap the plugs. When the motor is running, grab the front plug wire with your bare hand. Does it throw you across the garage? Same test but with the coil?
