Gs1085 plugs

[Guest]

Just wondering wot plugs you guys with wiseco 1085 kits are using, as i have a slight
misfire at low revs using Ngkb8es now i changed to me iridiums it stopped.

B8EV's on mine. runs perfect

U might have another issue. What is the voltage to your coils? It might be lower voltage at lower RPM with a big voltage drop to the coils has you mis firing.

Is it hard to start cold?

Coil relay Mod might be the answer and is normally highly recommended and almost madatory for high performance to insure good spark.

BTW I use the Irridums as well, but don't want that to mask another issue.

plugs

plugs

got a Dyna S ignition and green Dyna coils with Taylor ,leads it maybe the leads
but it sounds alot better with Iridium plugs fitted.
thankyou keepem coming.
got a new set of Dyna leads orderd so will try them.
someone told me to fit B9es plugs but havent gone that route yet.
it starts at a touch of the button it bumps start at half a bike length.

So what is the voltage at the (+) side of the coils? It is voltage drop due to connections and switch contacts

• from battery
• to ignition switch
• back to fuse box
• and then to right hand switch

that are the primary cause for voltage drop to the coils.

So how would I check that m8
dont fancey sticking me finger in Ht cap to find out, please excuse me ignorance,but
trying to get a local bikeshop checkin it for me at ?50 a hour is exspencive.
second problem is they only like scooters these days.

Different ways to do it but try it this way.

We are going to measure the total volatge drop from the + side of the battery to the plus side of the coil. This way we are not measuring how well your battery is charged but rather only how good the connections are.

find the plus side of the coils. Usually orange/white side. Put the + side of your volt meter to any bare metal of the contact on the coil + side (do not remove the harness connection). You probably have to remove the tank but not always.

Put the negative side of the volt meter to the PLUS (+) side of the battery. You should see no more than about 1 volt (it will register as a negative number). If you do (-) will be measuring battery condition and voltage drop together.

Turn key on but dont crank voltage should be over 11V preferable

If it says -2V for example you would only have 10 volts to coil is there was 12V at the battery.

lose the taylors!!!!!!!!!!!!!!! NO RESISTOR CAPS EITHER

get a set of dyna wires you WILL HAVE PROBLEMS

SEEN IT SO MANY TIMES

I've just got poxy B8ES's in mine and she runs just fine . Dyna S and standard coils .

Cheers , Simon .

B8EV plugs, dyna ignition, dyna coils,dyna leads, no 12v coil mod, no probs

Actually, the 8's are colder plugs than most people realise. My 850 misses intermittently on cold mornings for a couple of minutes until the plugs warm up enough. It's not through poor tuning. It's done it under several different states of carb tuning and when the PO owned it as well.

Just putting this out there.

Most of the better, more expensive spark plugs usually list pros like "hotter spark", or more "complete combustion". It's been my understanding that the REAL benefit to the fancy plugs is better anode material, and hence longer plug life. There are some different anode shapes (u-channels, those fancy dual and quad anode kinds), but I don't think those really generate any extra combustion by themselves, and are probably overkill for a stock or lightly modified GS.

Might it be the best practice to use standard NGK plugs to tune with. Like Pos said, you don't want fancy plugs to mask any underlying problems you might have. Tuning with the NGKs would also be cheaper, since you'll be doing lots of plugs chops with periodical plug changes once they get too colored. Once it's dialed, and you've insured there are no problems in the ignition system, you could then switch to the fancy pants plugs for the longer maintance interval. Sorta like using dino oil right after major engine work, since you'll be changing the oil relatively quickly. Any thoughts?

Plug chops ? What means this thing ? I like lamb chops and pork chops , but plug chops ?

Once I've run my "new" engine in , I'll put my Iridiums back in . I find the old girl is a bit more "spirited" with them .

Cheers , Simon .

a plug chop is what you put in your oven when cooking to see if it is running to rich!

Plugs chops, combined with plug reading are a method used to test the fuel ratio of each circuit in the carbs.

Any dyno figures? I'm sure there's at least some benefit other than longer life, but I'm not sure it's due to a better spark, or a better heat range than the stockers. To be fair, the first thing I reinforce on any vehicle I own is the ignition system, with the intent of eliminating any low voltage problems at the coils (can you tell I've had lots of problems in this area?). The iridiums may be able to provide better spark with sub-spec voltage at the coils. Dang, now I want to buy a bunch of test equipment so I can test all these ideas.

This is from the Factory Pro site. There used to be more detail but cant find it at the moment. They do sell them for $15 a pop, but I don’t think that undermines their credibility to much.

The Denso Iridiums, time after time, will improve fuel burn consistency, delivering less handlebar buzz (when tuned properly) -

I also found this old post where the data suggested more consistent firing to support the FP claims of better consistency.

One interesting thing about the data is that the NGK Iridium plugs have the most consistent set of runs. I'm not sure we can infer anything from this as I mentioned before, we dont know what the test conditions are. I guess I might be disappointed, but I am expecting an improved drivability for my stock 750 from a set of NGK Iridiums.

The data is from the previous post.

Interesting stuff. We all know torque is the number that directly correlates to fun, and the NGKs take that category along with the whole consistency bit. Good stuff to know, considering I'm in the market for a few sets of plugs in order to set up my carbs once the correct pilot jets show up. NGK shows them for about 8 bucks a pop, which makes them the clear winner in my book. Top torque number, consistent, and reasonably priced.

So , I've got to drill and tap holes in the oven door ?
How many do I need for bangers and mash ?
Mumma bear is gunna get pi$$ed . :lol: (again) .

I'm only just getting over the flogging I got for cooking my steering head bearings .

Cheers , Simon .

me too for dropping a gsxr swing arm in the bath and putting a nice big hole in it!
