Thundervolt 50 Spark Plug Wires...Simply Amazing.

[MDO]

I just today completed installing Thundervolt 50 spark plug wires, as well as new HD OEM plugs & DK Customs cooling deflector wings.

I have not got to hit the road yet for a test ride, but I fired it up & it was like a different animal.

The old plugs were not bad, so the new beefy wires get the praise.

I measured the resistance on the longest old wire & it was 14,000 ohms. This wire was a lìttle over 30" long. The new Thundervolt 50 wire of the same length was 90 ohms. That is amazing & my Freewheeler was a different beast & I can't wait for a test ride.

Thanks to DK Customs for selling a great product at a fantastic price.

Here is a picture comparing the OEM wire to the new Thundervolt 50

How was it different? Look forward to your ride report.

Thanks,

It felt like it was on steroids!

Good deal, less resistance = more fire to light the fuel

Back in the Shovel days, I got in a argument with a guy I worked with when I put a Super coil and big wires on mine. He said It was a waste of money. It didnt make any difference... Well his bike had a Super coil on it... It went bad and I gave him my old coil to use till he could get a new one... He was getting a stock coil... He couldn't believe how bad his bike ran with my coil.... He replaced his with a Super coil, and got big wires.... I won the argument :laugh:

Night and day difference

When racing we could run a bigger gap on the spark plugs using supper coils and Accel wires

Apples to Oranges .....:Shrug:...

Back in my drag racing days [early 60's] i ran packed 440 wires with raja clips...I got the clips and spools of wire from the local speed shops...And made them to fit though the spaghetti headers... The right wires do make a difference ....And the orange color was also cool looking......

Fuzzy, I'm a shopper & DK Customs has the best price on the web. That coupled with some fresh plugs was amazing to me.

I am also looking forward to testing the cooling wing deflectors, but we currently have some severe storms moving through.

The specs on the M8 plugs stated .031-.035"...I went with .032

The gap on the old ones was about .033

I got a 35 mile ride in in between storms & my Freewheeler is running great.

UPDATE:

I got a 90 mile ride in today and my Freewheeler is running great.

It's simply amazing to me that plug wires could do this. I highly recommend these plug wires from DK Custom Products.

Did your new plugs come in a box made in India?

Mine did, so far so good

Good on you for getting a better than stock wire set:clapping:

IMO, we cannot have a hot enuff spark especially with 4 plug heads

I believe HD got the combustion chamber right on the M8 engines, something the after market worked on for the shovels and evo engines

I agree about the M8 for now, I'm loving it.

I remember you mentioned the India thing with the plugs before & I used my GOOGLE machine.

Federal Moguls parent company is Tenneco & FM has facilities all over the world, including India.

Apparently, Bosch plugs are made there also. I thought they were German made.

Good to read you are enjoying the benefits of a great plug wire.

Here's the LINK to them for others wanting more details.

Over the years we've done a lot of testing on plug wires and we've learned a few important things-

1. Good Plug Wires make a difference you can feel.

2. Plug wires wear out (get weathered, crack, etc.)

3. Many plug wires, including OEM and Screamin' Eagle are NOT that great, and many times not to HD minimum Specs when brand new out of the box.

Thanks for a great product Kevin.

I found out Taylor was a Missouri company.

In my older cars, new plug wires would test at 7-8,000 ohms.

On my long test ride, I would estimate these to provide a 5% performance boost, judged by my seat of the pants dyno.orag:

The specs on the M8 plugs stated .031-.035"...I went with .032

The gap on the old ones was about .033

I forgot to mention, I torqued the new plugs to 100 inch/pounds. That is inbetween the specs in the service manual & I have always used it because it's easy to remember.

Just bought a set for my science project.... a very big THANKS Michael! Can't wait to actually hear the motor run and ride the trike to check them out....

I am going to the chalkboard now and write 50 times "I must remember patience is a virtue" orag:

Dual plug 2015

Does the tank need to be raised to change front plug wire

 

[Jack Klarich]

Does the tank need to be raised to change front plug wire

To make changing the wires easier pulling the tank is a plus, at least on my Freewheeler it made it easier

Not a hard job to pull the tank

 

[MDO]

Tucci, I've never changed plug wires on a twin cam. On the M8, the 4 wires are tie wrapped to the frame at various locations.

You have to remove the tank to do it properly.

Jack/Michael thanks. On the 15 fw, is changing out the wires worth the hassle. I was only going to do plugs. 26,000 on odom

What is the trick on detaching the gas line. I push up on the collar and the gas line will not come loose. Do I rotate the collar until it clicks than push or what?

I had this tank off before but I be damn if I remember how removed the gas line!

Lift up on the collar and pull down on the plastic line, they are a tight fit

 

[MDO]

I put a rag behind the fuel line quick disconnect & spayed a shot of silicone on it. They can get a little crusty after sitting a few years.

After what I learned recently, I would. You have 26,000 miles on wires that were most likely out of spec. in the 1st. place.

Joe, if you buy good wires and route them good you will be money ahead

Tried that. Didn't want to budge. If tried it on a friends bike and had the same problem. Has to be something I am doing wrong. Scratching my head on this one and frustrated.

Try a shot of silicone lube, rotate the plastic line a bit while pulling down

 

[DK Custom Products]

Try a shot of silicone lube, rotate the plastic line a bit while pulling down

And pull straight down from the quick release. Even a bit of an angle on the pulling down will bind it up.
