hi Andrew
hmmm ... I cant recall blowing a plug ... I did have a look on the liner and it seemed clean, but then again, I am no expert.
I'll try to give it a polish tonight ... is Brasso ok to use or do I have to use Autosol only ? I have a can of Brasso and plenty of super fine grit sandpaper that I used on my waterblocks and when I lapped my CPU.
if I get stuck, I'll just use the little Nova I have for the Sunday race and bring the 12TZ for you to have a look when you have a sec.

Have you ran the motor since polishing it?

Head shims wise .2mm is fine for us with 16% and you should you use 7 plug. make sure you leave bottom end needle flush with the housing TZ dont like bottom end lean at all(leave it alone) depends on what pipe you are using top end needle is about 1.75-2 turns out from fully close.
come and see me on Sunday I will try tune it for you. btw make sure clutch is set probably!

bit more information:
- have always been using plug P6 (that's what I have been told to use at my lhs when I bought it) so that's all I have at the moment, I will buy some P7 plugs before the weekend if I get a chance
- bottom end needle untouched, sems perfectly flush
- top end needle is at 2.2 turns from full close
- pipe is OS Tuned 1050 SC
- clutch ! oh gosh ... this is a whole another story, I have spent 1.5 hour on it last Sunday but not 100% sure if I got it right, I have a feeling that the black spring may be too hard (with yellow shoe) so yeah this may need more work
guys, I really appreciate all the help and advice, thank you very much.

The piston looks ok. Its not the liner that you need to check its the side of the piston for scratches. If there are no scratches you should be ok.
Looks like you will have plenty of help on Sunday.

no I have not ran the motor yet, can't really do it where I live so it will have to wait till Sunday.
yeah, the sides of the piston look ok ...
lets see how she goes on Sunday and if there is any life left in it ... dont really have spare $600 on new engine and pipe after splurging all that cash on the new NT1 and spares ..

yeah I remember now! you are right ...

thats another question I have actually about that ...
the head button is too hard to polish in the concave chamber area where the plug is sticking out.
I can polish the ring bottom surface area though ... the only question I have is I noticed it is not flat ... so when I ran it on the sandpaper, I saw the sides of the ring being polished, but not the whole surface so I was not sure if I should continue ...
thoughts ? I can post some photos tonight to illustrate what I mean if that helps ...

What i do is to rip a small piece of the wet and dry sandpaper about 1 or 2cm long and work it with your finger. I usually try and squish it into a little ball to do inside where the plug goes.
As the others have said try not to take the edge off. Dont try and sand it flat on a bench. You will stuff it.

I put an old glow in it and then chuck it in a drill; spin is slowly. I use dry wall sanding paper (looks like a sponge with fine grit sand paper on it) once it fairly smooth I then polish it.
