the plug leads I have on at the moment have a copper core

 

running the bp7es any problems with this as far as engine wise,

 

module, etc

[jaydee]

Use the R type.

The difference is only about 1kohm extra resistance and its enough to suppress unwanted interferencies thay may effect the module.

just ordered some ta will try

Also, by adding some resistance to the HT Circuit, the Spark will Spark for a longer period.

is that right so its best to use the bp7Res no matter what leads you use

 

it gets a bit confusing for me in my old age

 

don't the BP7es have a R on the plug haven't got a plug with me

 

but looking at photos on ebay theres a R on the plug even tho says BP7es

Too much Resistance isn't a good thing either, around 12k to 16k ohms as a guide would be fine.

 

If using Copper, like yours, then yes, the BP7RES would be the go, however with most Silicon Insulated leads (which usually have a Carbon Core), then the straight BP7ES's.

 

The photos that are often used on ebay are 'indicitive only', however, I'd suggest buying them over the counter.

ok ta

Iuse BPR6ES on a standard 1275 sprite

[Guess-Works.com]

In general, use "R"s, resistive plugs on those equipped with electronic ignition systems and the non resistive on those using points..

 

Also 6's are pretty much the defacto standard for plugs, only go up to 7's if you start burning out electrodes.... you may end up with a weaker spark using the wrong temperature plug.

reason got 7's is got high compression must be 11.1

see if I can get touch out the chambers when head comes off

let me get this right

 

if I am running copper leads I need to use bp7res plugs

 

if other leads can use bp7es

 

this is on my 65d dizzy

 

as copper leads and bp7es plugs may damage module ??

[Spider]

Bob,  I've filled in some answers in Red

 

 

let me get this right

 

if I am running copper leads I need to use bp7res plugs               Yes

 

if other leads can use bp7es                                                                Yes

 

this is on my 65d dizzy                                                                            Don't see an issue

 

as copper leads and bp7es plugs may damage module ??         No, they won't damage the Module. About the only things that will damage the Module is a Shorted Coil (on the LT Side),

                                                                                                                             High Temps and excessive Voltage (from memory, they were tested to 17.5 Volts)

what if I used those historic type plug caps from ngk that srcew into the lead they say supressed

http://www.moss-euro...teIndexID=12564

 

moss bros sell them about £3 each, can I use the bp7es then

Yes, no issues there.

Rather than start yet another thread on plugs I thought refer to this one and have a look on my favourite plug site.  They threw up 8 different BPR6ES!

 http://gsparkplug.com/catalogsearch/result/?q=BPR6ES 

 

Which one for a no-name electronic ignition on a fairly standard 1293?
