The wires were just ordered about 5min. ago. I never thought I would get "MORE HP". I was simply looking for better transfer of power for the spark. I use NGK Iridium plugs and, have been very with the results. So, why not add these new wires? The wires were only $39.95 (not an issue) and, if I dont like them I simply send them back and get a refund..........Spark plug wires do not increase performance or Hp, there is no magic there. However the factory wires do degrade over time which can cause performance related issues due to spark transfer, knock retard, etc.. something we have seen for years on the dyno, day in day out. Having the right wires and spark plugs is also essential for the adaptive knock retard to work correctly. We were approached by Moroso several years ago to help develop a line of wires for HD models, we spent a season testing various products and applications specifically with the HD-Delphi ECM & ignition components. The FM RaceWires are a great choice if you are looking for a high quality wire to replace your factory wires. They are 100% compatible with HD adaptive knock retard, they carry a lifetime warranty, and we offer a 100% satisfaction guarantee. Not alot of question there, if there is ever an issue we replace, or if you are simply not satisfied send them back for a refund.
I read the article and actually learned something. I don't want to hi-jack this thread, but how would you know if you had incompatible wires. On my other bikes I have only had to deal with knocking if I was at altitude, hot, too high gear, and on an incline. (so I drop a gear or 2 and give it some RPM) Almost like the engine is not making enough power and usually when riding 2 up. And all my previous motors were at least 10:1 compression.
This is something new to me - Compatible and Non-Compatible plug wires, beside the usual solid copper or carbon wiring.
In the schematic, it just basically shows the charge going through the biased zener voltage regulation diodes and the discharge going through the load resistors for the ION sensing signal.
Are compatible wires impedance matched or mis-matched to create some sort of resistance load for ION sensing??
