I changed my spark plugs about a month ago. When I pulled the wire off one of the plugs the boot ripped in half. It ran just fine like that but the plug/electrode was exposed so I ordered new aftermarket wires. I installed new wire set and now the bike is hard to start, really hard to start when its hot. I have put the old wires back on and it starts fine. I have repeated this process several times thinking I didn't have a wire seated correctly on the coil or plug. I even had a new set sent to me by the company but every time its the same thing - starts fine with stock wires(missing plug boot) and hard to start with new wire set. New wires seem top quality - Ironmachine. |

I guess my best option would be to order a new OEM plug wire if they are available. It just kind of has me baffled as to why my bike doesn't want to start with the new wires. It starts pretty well when cold, but not immediately like with stock wires. Once the bike warms up it gets real hard to start like I'm going to drain the battery. |

That is an interesting issue, I wonder if the aftermarket wires have a higher resistance or are passing less current into the plugs |

I have to say the guy I dealt with at Ironmachine was great. He says he stands behind his product and sent me new wires priority mail. So now I have two new sets of wires and same issue. I am going to put the plug end boots from the new wires on my stock wires and run like that. Would love to figure this out though. The new wires do have a larger O.D. if that matters. Also wondering if all years of XB's have the same plug wires ??????? |

Yep all XBs use the same plug wires
Just be careful routing them, if you don't get it perfect it is common for them to rub on the cylinder head, the vibrations will eventually damage the insulation causing running issues when it gets wet. At least that is with the stock wires, if these guys are thicker it might be more of an issue.
Good Luck! |

The wires may be resistor wires. They were/are used to suppress RF interference. I've used both in tubers with no issues.
It may be that your coil is getting weak. Doesn't happen often but I've seen it before. A weak coil won't have enough "oomph" to get over a resistor wire. |

Thanks for the help guys. I did put the new plug boots on my stock wires and it starts and runs perfect. Has anyone else used these wires from ironmachine? Seems like a good product. Interesting thought about the coil, but the bike only has 1900 miles on it. |

If the Iron machine plug wires do have higher resistance that could over work the buell oem coil |

The guy from ironmachine said these wires actually have less resistance than stock wires. He thinks there must be some other issue - I think I need to find a
buell mechanic in the Detroit area. Any body know of one? |

You said the bike is now running good with the new boots on the old wires.Leave it alone and stick to what works. Use the OEM wires.If you have to do your own resistance check using an auto ranging ohm meter.your service manual will give you the correct reading of what your looking for.GO Ride !! Don't try to make the shoe fit. |
