I have a 2003 883r.I was out riding today and the bike started backfiring and sputtering.I got it home and pulled in the garage.It was dark in there&nbsp\\; and I look at the motor and the plug wire for the rear cylinder is arcing.It is doing this right at the coil.From the rubber boot to the top of the motor.Do i need new wires?Or coil?Any help would be great

 

I'd be tempted to replace both if that happened to me.&nbsp\\; Or, replace the wires first to see if that solves it (the cheapest way).&nbsp\\; If it still does it, replace the coil.&nbsp\\; If still doing it, drop back 10 and punt.&nbsp\\; Of course this is just my uneducated, non-mechanic opinion.&nbsp\\; Hopefully someone will come along that actually knows what they are talking about.

 

What chefe said.... you may have a bad wire, but if there is a crack in the coil case, you will need to replace the coil.

 

+1, replace the coil wire first, then if it still arcs, replace the coil.

 

Well I got a set of Accel wires and that did the trick.Thanks for the help

 

Good to hear you got it sorted out.
