On changing the spark plugs I found the front two to be sooted up therefore running rich and the rear two to show signs of running lean i.e sandy coloured electrodes.
So what's the problem and where's the fix?
Think I know the answer but you lot can get yer post counts up by confirming what I probably already know.

Erm... throttle body synch ??
That's more of a guess than an expert opinion - unless it's right of course

You could try putting one of the plugs that's running lean in with one that's running rich and they will ballance each other out

Don't worry, now you've got the Rene air box on, you'll blow off all the soot.
