If it didnt start again, take the plug back out and warm it up until it dries off, then try it. (This worked on my bike once)

well theres a ngk 4122br7hs one in there now the one i took out was put in but the people at the two wheel centre, which was a denso w22fsr. what does "running rich" mean and how do i fix it?

Doddmaster · World Chat Champion Joined: 02 Feb 2002 Karma :

Running rich means you have too much oil (or not enough petrol) going into the engine

Doddmaster · World Chat Champion Joined: 02 Feb 2002 Karma :

To fix it you have to play around with the carb - you need to find a manual on the net for that

hopoffbaby · Spanner Monkey Joined: 16 Mar 2002 Karma :

does this affect proformance?

probably does- could make it slightly slower

Scotty · Scooter Boi Joined: 31 Jul 2002 Karma :

wouldnt imagine the compression would be as good as it should be.
As fuel / air mix would be slightly off.
But then again scoots have variators to make up for it i supose. lol

Hi

Wet plug is a sign of running rich, which means too much fuel for the amount of air. Also a sign of too much oil. However, can also be caused by a plug of the wrong grade (plugs work over a narrow temp range, and outside that range they either fowl up if too cold or start to break down if too hot)

First thing to do is check the plug you have is the correct one for your bike

All the best

Before you alter things how long had you been running before taking the plug out. Run the bike normaly until fully warmed up, do this by riding it, when you get back from the ride just turn the engine off don't rev it.

Then let it cool a little remove the plug and examine it, it is black and oily you have a mixture problem.

Just running the engine without properly running under load will give you a wet plug as the carb settings are optmised for normal running under load.
