plugs and wires questions

[kilog55]

ok i need to replace atleast on plug cap it is cracked in a few places close to shattered actually now how do we go about getting new wires and caps?

also i have a set of BR8ES plugs here my bike calls for B8ES i know the R is for resistor can i run these plugs with any plug cap? or do i need to get a specific one?

i also would like to upgrade the wires to something more performance geared do they make better wires for us and in colors other then black?

should i use the oe style plug caps or rubber ones or what? and what part numbers how do i figure that out?

Plug caps unscrew from the wires, good idea to remove them and inspect for corrosion. Make sure you cut the wire back a bit (1/4") to expose fresh copper.

NGK replacement caps are a favorite here.

If you are running OEM coils, the plug wires don't come out of the coils...

[kilog55]

yeah OEM coils as far as i can tell they have the goop around em at the coil.

what about R vs regular plugs does it matter?

[hikermikem]

The plugs shouldn't matter, either will be fine... If you have a radio or an on-board communication system, the R plugs are preferred to minimize electrical noise...

good on the plugs but man why so many choices on the wires?

[kilog55]

the correct gap is 0.024" - 0.028" for a 850 correct?

[hikermikem]

The Suzuki service manual for my 850GLZ lists .024"-.031" gaps, same plugs.

you CAN replace wires on stock coils, i have done it. someone asked about this just a couple weeks ago, you could probably find it in a search

alrighty i had a clymer manual but it is missing mysteriously

Why replace wires? Unless they are really shot. Most of these old bikes had stranded wire ignition cables, unlike cars that had a supression wire with a fiberglass core. Your spark plug caps just screw on, with the screw in between wire and insulation to make contact. Just trim an inch or so off the end of the wire and screw on a new cap.

alrighty like i said the cap is what i am confused on, i want OE look so i guess i need the 120* long and short?

Hi Mr. kilog55,

For plug caps, you need 2 each - NGK XB05F and VB05F.


Thank you for your indulgence,
