New wires
« on: February 10, 2016, 02:15:43 PM »
As part of my winter revamp, I'm going to be replacing plugs and wires on my 1990 K75RT.  I was going to get the set offered by BeemerBoneyard, but then saw these: 

http://www.ebay.com/itm/231841098974

Does anyone see a problem with these mated with Bosch X5DC plugs?

And is there a better (or equivalent) plug that I should consider?  NGK D7EA, perhaps?

Thanks!

According to BMW experts and others the use of NGK leads will blow up your computer, and you and your bike are condemned to HELL.I have ran NGK leads for the last 17 years living in terror. NGK leads require the removal of the nut on the centre electrode I don't think you can do that on Bosch plugs. So you will need to run the NGK D7EA's which are perfectly fine. You will however join a long line of BMW owners, queuing up, to go to HELL over the use of these DAMNED leads.
See you in HELL Martin.

Well, I'm pretty sure I'm already going down, so...  But seriously, is the difference with the non-OEM wires the discontinuity gap in the OEM wires for the K75?  Or is it where the resistor lives?  Both?  I'm not sure I fully understand the whole thing, but I'm certainly not interested in paying $70+ each for the BMW wires.

NGK is the plug of Satan.  Trust me you won't be lacking companionship down there.  Check the NGK site for the correct plug for your brick.  If it has an R in the designation after the D you need plain wires.  If there is no R then you need resistor leads.  My bricks use both, and I am always confused so won't tell you which you need.

What Martin said...come join the lot of us destined for the netherworld.

Seriously,  zero issues with the NGK wires.

Due to people using NGK leads despite the ominous warnings, I have been informed by the Lord of the Netherworld that due to limited space, HELL is to be expanded. As this will take sometime, it will not be possible to house all future occupants. So BMW NGK users as the greatest sinners by using  these damned NGK leads will take preference. All Hardley  and wannabes rebel riders are to be downgraded to Limbo.
SO SAY THE LORD OF THE UNDERWORLD.

Hmmm... perhaps it would be better to just get new Bosch plugs and forget about the wires?  I have no indication they are bad; I'm just trying to do preemptive replacement of things that make sense.

The world's been going to hell in a handbasket for quite a while now...

Obviously the management of he'll ain't worth a crap. 

Perhaps this is intentional.

The sales force for it is doing a damn fine job though...

CORRECT.....if the leads ain't broke, just get new Bosch plugs. (Once the inmates start talking about hell, they quit listening.)

Marshall every time I tried to use Bosch Plugs they were not compatible with my NGK leads as the nut on the centre electrode was not removable. I have not tried to use them for quite a few years, but I have never had an issue with NGK. Can you remove this on US Bosch plugs?

Bermuda sorry if we confused you I have ran the same NGK leads for the last 17 years, and my mate has run them for 6 years. When he got his I also got a spare set which I have not used. However I have to run NGK plugs as I haven't been able to find Bosch plugs with the removable nut. I have not had any problems with the leads or the plugs and would recommend them.
Apologies for the confusion Martin.

I actually removed the nut from the bosch x5dc plugs that were in my bike and put them on the NGK plugs when I swapped plugs a few months ago.  worked fine.   I am also running the ngk wires WITH the nuts on the plugs.  no issues.

  The nuts on the Bosch Plugs I have bought were non removable, It has been quite a few years since I have tried to buy them. But I have no issues with NGK. and I have to remove the nut to use NGK plugs. I might investigate again.

The nuts on all the x5dc plugs I have used over the years have been removable.  (Bmw specs the same plug for the early M cars)

Or I could be getting senile and not remember correctly. ...

Got the new plugs in today (decided to leave the OEM wires alone) and am wondering about the amount of oil I found on the threads.  The center and ground electrodes look fine, but the threads were quite oily.  My K has 55,000 miles... so, anything to worry about here?

Marshall I think I have discovered a difference in the NGK caps, yours come out at 45 deg, mine come out at 90 deg. Mine you have to remove the nut and yours require the nut.

There are always things to worry about here, BB, but going to Hell isn't one of them, apparently. If the electrode is tan, the engine isn't blowing enough blue smoke while you're running it to hire yourself out as a mosquito fogger and the moon isn't reflecting from a pool of oil under your bike, move on.

Thanks Laitch - I feel so much better now... I think.  :-)
