Thundervolt 50 Spark Plug Wires...Simply Amazing.

Silicone

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.

Nice tip about the silicone. I was having a tough time moving the chrome fitting. Sprayed it, rotated several times, it lifted up and the hose just about fell off!

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.

Thanks guys. Will try that once I get back in town! Am out of town for the next week.

On the 2015 Freewheeler, does the tank need to be removed or is there enough room to change front wire by loosening the front and rear mounting bolts

No removal needed on my 15 Freewheeler

The 17 M8 it is a must

Jack, your are fountain of knowledge! Now one more question. You said you used hd plugs. Regular 6r12 or did you go with the screaming eagle 6r12g

Stick with stock plugs

The reason I say this is

1. your TC engine has Delphi Ion Sensing designed into the ECM

2. changing to a plug with a different resistance will cause the ECM to read this signal as much as being out of spec, this could cause timing issues and up to including a trouble code

3. stock plugs are cheaper and your engine was designed to run with them

I have tested and run many plugs on many HD engines, I always come back to stock

Completely mind boggling. I'm coming from the stage coach era into total computerized, concerning engines. Without someone with your experience on this site i could very well see a massive amount of money being wasted on repairs/shop hours on simple things like this(spark plugs etc)

Tucci, I stayed with the stock plugs on my M8(6R10) After 2 years, they looked very good and all 4 were identical.

With my 10% Veterans discount at my dealer, they were $19 & change for 4. I can handle that every few years.

I was gonna try NGK, but I ended up getting the wrong tip & it was a big hassle that was not worth it to save $8.

The site Jack referenced was an eye opener in that ,one "small" variable in the electrical/ignition system on the newer engines can cause an untold amount of problems. And i'm sure you know, when it comes to electrical gremlins you're in limbo
