Cementy grey stuff on inside of point covers etc

[AshimotoK0]

Had to remove the cementy grey stuff on the inside of some points covers prior to stripping the plating a week or so back. It comes off pretty easy if you immerse the cover in strong, hot caustic soda solution. I assume it's there to prevent 'ringing' of the thin metal plate when subjected to engine vibrations or possibly an insulator but I doubt it. Anyone know what it is? If not I could get it analysed to see what it consists of.

Sounds like a damping medium to me too

I found the same on the inside of mine as well Ash. It looked like someone had been using it as a mixing bowl for exhaust paste or something similar. I just soaked mine in Fairy and it came off quite easily. I have been told since then that it is something to stop arcing from the points, not sure if that's true or not but, would make sense I suppose.

I thought that too Julie but you get it on both covers on the 250K twins, not just the points one.

Well Ash, that pissed on my theory then  .

Having met you Bryan, I know you are a Gentleman. Ash, on the other hand, I have not yet met so, only time will tell

Julie, It took an act of parliament to make me an officer, it would take an act of god to make me a gentleman!!

[MCTID]

Or as the RSM said to the young Officer, 'Speaking as an outsider, Sir, what's your opinion of the human race'?

Tee hee......

Take it from me Bryan, up against most of the reprobates I know, you are definitely a Gentleman

I just got a (gentlemanly) brand new timing cover for the 750 and its got the grey cement inside it. Must be a noise thing.

That's just what I thought when I saw mine - it looks like the sort of mess I make on bits of cardboard when I'm using body filler. I didn't think for a minute that it was OEM.

[MCTID]

Jule, why would you want to use body filler?
I thought that you would have a 'perfect' body.....being a Member of this Forum........ Tee hee.
