Spark Plug Wires ??

I only ask because the OEM ones really suck.

It might be that they heat up and lose conductivity. When they cool down they work again until they heat up.

Of course, I could be wrong.

Is it an RT or an RS(GS)?

Are there any codes?

First bike was a 2010 RS, and when I had backfiring it turned out to be the exhaust gasket. Replace them with the Honda's, and they will last longer.

I agree, along with plugs.

I'm thinking Spark plug wires, You might even see them arcing,
Warm the engine, Remove a side panel, and in a dark garage, slowly rev the engine and look at the wires,
You might even hear them sparking. :dontknow:

:agree: Loose or lousy plug wires; they'll also screw up your plugs, so get a new set of them also...
BajaRon has what you need! :2thumbs:

I would suspect bad spark plugs...possibly installed without the necessary thermal transfer paste, and/or bad plug wires. These will not show on a diagnostic. There are other possibilities, but the plugs/wires are the most likely suspects.

Could be a relay getting hot too, might want to check those and make sure they are all seated good.
