I lost my license ages ago and so I haven't been riding my bike, however I wanted to start it/drive it down the road and back just to get the engine turning over. It hadn't been ridden in about 3 weeks.
Well, it turned over, but wouldn't start. So I thought, pfffft no problem, I'll push start it. Now you must realise, I live on the side of a valley, so there's a brilliant hill right outside my house. So I get going down this hill, drop clutch, engine turns over but just engine breaks and stops the bike. Try again.
Did that for a while. Didn't get anything out of it.
Anyway that was on Saturday. Today I had some time and 2 friends over, we moved all my tools down to the side of the road where I'd just pushed my bike onto and set up shop.
We checked everything, fuses, coils, carbs, fuel lines, finally spark plugs.
Holy crap were the spark plugs oil fouled. Majorly oil fouled.
So, not having any transport to the nearest auto-shop, we decided we'd clean them.
about half a can of degreaser and a lot of wire brush scrubbing later we had some damn nice looking spark plugs. Doused them in petrol and chucked them back in the bike.
So I ride it back up the hill, my friends and I go an eat celebratory pizza and play celebratory EUFA =D
So then about 30 mins ago I decide I'd take her for that ride up and down the road.
Try starting. Nothing.
Oh I'll just push start it down the hill.
Exactly the same problem!!
How could the plugs have fouled so quickly!?
Zion Motorcycles on Oil fouled spark plugs:
"A spark plug shorted by excessive oil entering the combustion chamber is shown below. This is often caused by piston rings or cylinder walls that are badly worn. Oil may also be pulled into the chamber because of excessive clearance in the valve stem guides, or badly worn valve stem seals. If the PCV valve is plugged or inoperative, it can cause a buildup of crankcase pressure. This condition can force oil and oil vapors past the rings and valve guides into the combustion chamber."
sounds like pretty serious stuff.
so now I'm wondering how screwed am I?
I'm planning on putting new plugs in tomorrow, but after reading the zion thing, it sounds like I've got other things I should be worried about.
