Is it possible to recover plugs that have been oiled?

Hello,

I've got a small issue with my KE100. I used a small amount of choke and oiled another plug. This is the second time it has happened in as many weeks.

This means that I have two plugs which no longer spark.

Is there any way I can fix 'em? otherwise this bike's running costs may be rather high, and I might have to carry the worlds supply of B8ES 's.

Thanks,

Mark.

Cook 'em on the gas stove. Line them up on the centre so that the earth-strap is poking out above one of the flames and get ot glowing a dull red. Might make the kitchen smell funny Smile

Using choke shouldn't cause plug-oiling though. You should try to cure the problem rather than the symptom.

Well if you're oiling the plug it's either getting too much 2-stroke oil in the mix or drawing gearbox oil in through the main bearing seal. Is it run on pre-mix fuel or oiled by the autolube pump?

In that case you should notice it using a lot of 2-stroke oil.

Most autolube systems have a mark that you line up on full throttle. Look at the cable quadrant on the autolube pump, there should be a line or a notch. Open the throttle fully and watch the quadrant turn - you'll most likely see the mark on the quadrant go past another mark on the pump housing on full throttle. You must adjust the oil-pump cable until the marks line up.

If you're not sure post a photo of the oil pump.

Also check the cable for perfectly free operation especially if it has a splitter device half way down. If the cable-end has got caught-up inside the splitter, it might not be sitting down in the locating hole, and that could be opening the pump too much. If you adjust it to turn the oil supply down and it goes back how it was you'll starve your engine of oil. Check it carefully.

It would take very little gearbox oil getting past to cause a massive amount of smoke. If the pump is set right, you're gonna have to split the cases and fit new main bearings and seals. Not as daunting as it sounds but will cost around 50-quid or so all-up.

Use a hotter plug. Chuck the oiled ones in the bin Smile

I think that bike has a really primitive diaphragm pump which squirts oil in when you twist the throttle: i.e. not the more clever kind which run constantly (pump off the engine) and then the throttle position meters how much oil gets through.

Its only done 5,000 miles (according to the speedo)

So should the crank seals need replacing?

The gearbox is one of the smoothest I've used on any bike... I'm not certain that it is burning gearbox oil.

I'll check the pump tomorrow, and buy a hotter plug. Smile

Does the gearbox oil smell at all of petrol? That's the best way to detect a knackered primary drive crank seal (along with the oil level dropping). At 5000 miles it's unlikely to of failed, but if the bike has been stood they can fail on startup. As above a fresh plug and decent run will do it the world of good too.

No a 9 is cooler, a BR7ES would be hotter.

I have also given them a good wire brush then a scoosh of carb cleaner which seems to get them back.

Make sure you have set the plug gap correctly.

It is quite possible there is a load of ming* hanging about in the bottom of the crankcases which is what is oiling up your plugs. Once it gets a good, flat-oot run it'll burn it all off and sort itself out.

What you'll probably find is when you first take it out on the road it'll stutter, bog and refuse to rev over a certain point when you first try to open the throttle. Hold the throttle at the position where it does this (so you aren't over-oiling it). It will eventually go stutter, stutter, cough, stutter, cough, COUGH! Then it will squat down and take-off. If you look behind you at this point you'll see a pall of blue smoke, on a still day it may even be swirling round in a perfect spiral in your wake. This is your engine expelling the ming.

* A technical term for the sludge of unbruned 2-stroke oil and coke to be found in the crankcases and exhausts of air cooled 2-strokes that have been sat for a while.

I happen to have a couple of plugs lying about which were for my Mazda MX3.

Due to a sordid conspiracy between the Mazda car company and the spark plug manufacturers, it is impossible to buy spark plugs in packs of six, despite my old car having six cylinders.

The plugs match the pitch of thread and the depth and the diameter perfectly but they are Bosch and so do not use the same numbering scheme as NGK.

I've just looked up the NGK equivalent and its a BKR5E. Which is identical apart from the temperature and a smaller hex bit for use with a smaller plug spanner.

And of course the temperature... its a lot hotter. I'm assuming that I'll hole a piston with that plug? That is of course if the Bosch plugs are the same temp as the NGK ones...

Try www.sparkplugs.co.uk

There is a parts lookup on your car make and model, they sell all different makes.

I used them once, the plugs were good and cheap and they arrived next day.

Hmm. This site says the Motorcycle equivalent of a BKR5E is a BR8EG...

thats weird! Laughing

The gearbox oil does smell of petrol.

The Oil pump is correctly calibrated.

I'm hoping that the crankcases are just full of ming as stinkwheel suggests, else I'm going to have to fit a new crank seal. Sad

It's disc valve isn't it????....Bugger....plenty of places for oil and petrol to share the wealth other than the crank seal. Luckily you should be able to change the crankseals and and o-rings without splittling the casings. I had an old suzuki A100 and never properly cured the ingress of gearbox oil into the induction mix....what a twat that thing was.
