Is there an aftermarket ignition upgrade setup?

As I look into doing a tune-up on my bike. I gather that the coil setup is a "poor" design with the plug wires.. Is there an aftermarket replacement/upgrade!?!

Thanx,

Starring Jack Nicholson, I present you with "As Good As It Gets":


ic3) HCP245 Aftermarket DYNA HIGH-OUTPUT IGNITION COILS, a pair of high-output (40kV) replacement coils. 3.0 ohms primary resistance means you won't be burning up your TCI box; 14.4K ohms secondary resistance means you get a much more serious spark than a stock factory coil will ever produce. Both the primary and high-voltage (output) terminals are brass, which means they'll never corrode; no exposed laminations to rust or degrade over time; and each coil is fully and completely ultrasonically welded shut and encased in a tough thermoplastic shell to prevent any problems with moisture intrusion (a real problem with older factory coils). Output terminals accept either 7mm or 8mm wires (note that wires, output boots, and spark plug caps are NOT included).

NOTE: for most XJ model bikes, these coils will require you to fabricate special mounting "U"-brackets to properly mount them into the stock locations, as well as an assortment of different length bolts, washers, spacers, etc. You want to end up with the coil output terminals facing "down" (towards the engine) rather than "out" (towards the horizontal) and that is why you need to fabricate brackets. Not hard to do, but rather time-consuming.....it's cramped under there! You may also have to re-route some wiring harnesses and/or relocate some relay holders. Plan on spending 4 hours planning your install and then a couple of dollars in small parts!.

Models that mount the coils up on the steering neck (some 700 models) will also have to fabricate brackets.

Spark Plug Wires:


spw1) Aftermarket SPARK PLUG WIRE SETS feature a solid copper-core, non-suppression (zero ohms resistance) and are needed when using aftermarket Dyna coils. Each set contains two 4-foot length of 7mm wires with a tall, molded rubber 135-degree angle plug boot on both ends. Cut each wire in half, and now you have four (4) two-foot long wire segments, each with a molded 135-degree angled rubber boot on one end (and a bare wire on the other end, which become the coil end of the wire). Kits come with four coil-end brass crimp-on terminals, a straight rubber coil cap, and installation instructions.

NOTE: you can, of course, cut the wires down to any needed length (two feet is actually too much for most XJ models), and, if you wish, you can cut off the molded rubber plug boot and use the original style NGK resistance caps for a "factory" type appearance. These copper-core wires, boots, and terminals are zero-resistance throughout, which is the ideal situation for situations where electrical RFI interference isn't an issue (like on older motorcycles!).



HCP4014 Aftermarket 7mm cooper-core, non-suppression (zero ohms resistance) BLACK Spark Plug Wire Set, more than enough to do one bike.
$ 18.00


HCP4015 Aftermarket 7mm cooper-core, non-suppression (zero ohms resistance) RED Spark Plug Wire Set, more than enough to do one bike.

But before you order, you really owe it to yourself to read this:


Coils and Related:


ic1) OEM and aftermarket IGNITION COILS replace damaged, cracked, or out-of-spec originals to help "light that XJ fire" under your...well, you know. Twenty-plus year old original coils can suffer from a variety of ailments that prevent them from doing their job, including burned or shorted internal windings, hairline cracks in the outer cases, or damaged and destroyed plug wire leads.

NOTE: although all of the following is repeated below under the spark plug Caps section, it would be good to review it here, also. ALWAYS TEST YOUR COILS (as described below) BEFORE ASSUMING THEY ARE THE PROBLEM. AND ALWAYS TEST YOUR COILS IF YOU ARE HAVING MIS-FIRING, FOULED PLUGS, OR OTHER (POSSIBLY) IGNITION-RELATED ENGINE PERFORMANCE PROBLEMS.

This will save you an incredible amount of time, effort, and $$$ and give you more quality riding time as opposed to a greater quantity of diagnostic time!

If you would like to have a childish, hand-drawn diagram e-mailed to you of "how to test your coils", please e-mail me (info@xj4ever.com) your real e-mail address, and request the "Coil Testing Diagram", and I'll provide it to you for free.

And a final note: using hi-performance, aftermarket coils (like Dyna or Accel brand) will generally NOT "improve the performance" of your bike in any measurable, meaningful way if your factory coils are performing okay. If your factory coils are not up to snuff, then certainly ANY replacement (stock or aftermarket) coils are going to eliminate such problems and "improve performance". Be aware, though, that aftermarket coils can take quite a bit of mounting bracket fabrication efforts to make them fit properly into these cramped XJ frames, and you will have to purchase the plug wires, boots, and caps separately also.
