Hi all,

My GRiSO 1100 has 42.000 km on the clock and I have never changed the so called "internal" spark plugs (or even checked if they were tight...).
How bad can this be? How hard is it to get to these things?

Thanks, Matias.

You need a thin walled socket to get them out as they are in very close proximity to the fins. Before attempting to remove them make sure you blow out the area around them vigorously with compressed air as all sorts of rubbish gets stuck around them, gravel, insect corpses etc. all of which will take the opportunity to drop down the plug hole into the cylinder if they aren't evicted before the plug is removed.

Having been left in for so long they are likely to be seized in pretty tight. When trying to remove them make sure you apply as little sideways force as possible try and keep the extension to the socket as close as coaxial to the plug. If the plug does snap chances are you'll need to take the head off to extract the threads from the head itself.

Apply "Kroil" or your favorite penetrating oil after blowing out the well
Let it sit before applying wrench JMO

I did this for a few days, riding in between to get the engine hot for more possible penetration. The exterior of the plugs was severely rusted.

I'm glad I didn't read Pete's warning about them snapping before I took them out. I have enough anxiety in my life!

On a somewhat related note, ordered NGK`s from Summit Racing back in April when I bought the bike
They arrived TODAY !

Very Happy
