PJPR01 Posted November 19, 2019 Posted November 19, 2019 Has anyone found a good source (link?) for high quality spark plug wires that will work on the 2002 Scura? The MG sites I've looked at do not specify anything for the Scura, only earlier models. The "generic" build them yourself seem to leave doubt about the resistance in the cap...bit of a guessing game. Nothing reliable on Ebay either other than used stuff, would prefer new. Thanks in advance!
po18guy Posted November 19, 2019 Posted November 19, 2019 Try a pair of these: NGK CR6 individual wires. About $18/per. 5K resistance cap. Other specs are on the eBay listing. https://www.ebay.com/itm/NGK-Racing-Wire-90deg-Solid-Resistor-Cover-100cm-90-100cm-8736-N-CR6/333270758936?epid=171310303&hash=item4d987c3618:g:kyQAAOSwv7BdMMC8 1 2
MartyNZ Posted November 20, 2019 Posted November 20, 2019 Yep, they are good. The white writing can be wiped off with isopropyl alcohol if you think it looks pretentious (although the words "racing cable" does add 2hp ). The sleeve can be slid along the cable to protect against chaffing on the frame and cylinder heads. 1
po18guy Posted November 20, 2019 Posted November 20, 2019 It almost seems like Guzzi designed the entire bike and then thought, "Oh crap! We forgot the coils! Well, the only space left is up front, so we'll just use 1 meter cables." Scenario: Officer: "I was going to let you off with a warning, but I see you're using RACING plug wires!"
PJPR01 Posted November 21, 2019 Author Posted November 21, 2019 Racing Red no less! 2 hp increase...sign me up! You're right...these cables are long, and my current ones don't have anything to protect them from the cylinder heads....so a good option here. After this great option above, I also got a lead from Curtis at Harper's...recommending the following wires as well, when I read the description at first I didn't think they'd work, so will have a backup set. http://www.harpermoto.com/twin-coil-spark-plug-wire-set-t-and-newer.html

Someone correct me if I'm wrong here.

PJPR01 Posted November 21, 2019 Author Posted November 21, 2019 My current ones are red, not sure how to tell if they are OEM since I'm not the original owner. Either way, one of them needs replacing, so a new pair will be going on as soon as these replacement ones arrive. Thanks all!
docc Posted November 22, 2019 Posted November 22, 2019 Not sure about the wires, but early 5000 Ohm resistor caps were Champion while later V11 were NGK . . .
PJPR01 Posted December 23, 2019 Author Posted December 23, 2019 Well...I got both sets of wires as suggested above and the Harper's set, but the plug ends I tried to use for the red NGK's were the wrong ones, so I decided to use the set I received from Harpers. Basically you cut the wire in half, thread on the end caps and voila, you have a pair of plug wires in 2 minutes flat. They made an amazing difference, bike runs noticeably smoother...I'm guessing that my old plug wires may have been either originals or quite old, but happy to have a new set on...black, rather than red, but functioning perfectly! Still hunting for where I can find the right size metal end caps (the part that fits into the distributor end) for the NGK's so I can keep those as a backup...
footgoose Posted December 23, 2019 Posted December 23, 2019 I'm not sure I understand why they won't work. They won't attach to the spark plug? or the other end at the coil
PJPR01 Posted December 23, 2019 Author Posted December 23, 2019 Well...the red NGK's didn't come with the metal end that gets inserted into the coil, so I had to buy some after market ones by guessing looking at my originals. Unfortunately the ones I bought were the wrong size and I could not get them to insert...in the meantime, the set from Harpers had arrived and they came already prepped with the coil end on the wires, and all I had to do was attach the plug end.

I have some end caps you can have for nix. They are made for 6mm cable, so you would need to trim 8mm cable a little. PM me your address. 1
