Since Harley dropped the XR1200 from their line the dealers in this area are not stocking the 10R12X plugs anymore, except the one dealer who was a Buell seller, and I don't do business with them. There are 5 cross-reference plugs listed as: Champion 1005 Champion RA4HCX Denso IXU24 Denso VXU24 Denso XU24EPR-U Are all these equivalent in performance and heat range, or are some cooler than others? Which are the most available? Any found at typical auto part stores? Any of you used these non OEM plugs in your Uly? With what kind of results? Any of you guys ever buy the long plugwire kits and clip to length for your Uly? The OEM plug wires are too short, IMHO. | ||

I've been using the EPR-U plugs for the last 40k miles. They seem fine. | ||

@Mark - Are they readily available over the counter? | ||

Another option is the NGK Iridium DCPR8EIX 6546 . Order at any auto parts store. Supposed to be their "high performance, long life" plug. They are more expensive, maybe a waiste of money (?), but it's only two plugs... | ||

...or just get Lance to send you some 10R12X's....support those who support us, and all that. | ||

Put the Harley V-Rod plug in my son's bike a couple of years ago and no problems. The 2009 V-Rod used the 10R12X plug. | ||

I've been running NGK DPR9EIX-9 Iridium plugs in my '06 Ulysses since 2007. Bought them from American Sport Bike. They should be available at any motorcycle or auto parts store. | ||

I got a couple of NGK DPR8E plugs at the autoparts store last night. hopefully they are in the right temp range for my region and the season. Next comes plug wires. Anyone have experience with those "make your own plugwire" kits where they give you one long wire and you cut to length, then crimp on the coil end caps? | ||

I usually call ahead to be sure that they are in stock. I have an O'Reilley's and an Autozone within one mile of home. I don't find it to be a problem because I only change the plugs every couple of years. Even then, the old ones always seem to look fine. Clean, with nice, sharp, edges.

Magnacore wires, https://jmautosports.com/magnecor/magnecor-kv85-co mpetition-85mm-plug-wires/2557/i-400790.aspx I use the NGKs in the 9 range. | ||
| Tempest766 |
So which is hotter for the NGSs: 8 or 9? My understanding is that the plug needs to burn hot enough to keep it clean, but not too hot, lest ye risk pre-ignition or some other such apocalyptic event. | ||

The higher the number the cooler the plug. | ||

@Ourdee - Thanks! | ||

Remember - that applies to NGK plugs (higher is colder) | ||

Tempest766 Posted I got a couple of NGK DPR8E plugs at the autoparts store last night. hopefully they are in the right temp range for my region and the season. Next comes plug wires. Anyone have experience with those "make your own plugwire" kits where they give you one long wire and you cut to length, then crimp on the coil end caps? Those plug wire kits work great for the perfect fit but I would strongly advise getting the special spark plug wire crimper for that nice secure crimp. You can do it with pliers but it never comes out as good. I use my crimper on my c3 corvette and anything that needs a spark plug wire made. | ||

I replaced the plugs but didn't do the wires: NGKs (8 range) set at 0.037ish Interestingly, with the old plugs the front cylinder was heavily sooted and the rear was cooked white. God, I hate air-cooled V-twins! Regarding plug wires: There is so little wire used anyway. Most of the distance is taken up by the caps on either end. I did clean up the insides of the caps and put some fresh dialectric grease in there. | ||

Ordered a set of those wires ourdee posted above and I got this : Manufacturer states no stock and no ETA. Order has been cancelled | ||

Wow. Glad I got them in time. Truth be known, the OEM wires work. |
