oil on spark plug :-s

[sticlistul]

Today I've changed the original spark plug  (at 14150km) with an NGK C7HSA and i've start the engine ,run it for about 4 min and when I've taked it out I find oil on thread the top of the spark it wasn't wet ( but it was black I think is beacouse of airfilter ,I didn't change yet and it could run rich) or it can be from the oil ? so do you have oil on spark plug ?

...sounds like a rich condition....

..did you just run it at idle??

..if so, you can adjust your idle screw clockwise slightly to reduce the amount of petrol in the fuel mix...

yes it was at idle I've cleaned the air filter with a vacum (until I change the air filter with a free flow one and a 88main jet )And with that I hope I will do 80 km/h on flat , but for next plug chop reading I will cleen the spark I have now with a wire brush ....I don't want to buy an other one

[wordslinger]

...probably gonna be more like 72-75 kmh on th flats...

I already have 70-72km/h on flat ( and I didn't get the new rollers yet ,this one are prety damaged ,I just hope the 5 g rollers don't cut my speed)

Even tho you have a stock paper element you can still use gasoline to clean it. A small pan will work to sort of shake it around in. It will work much better when it cleaned out. Just be sure to dry it well before using.
