That looks pretty good, just maybe a tad on the lean side, hard to tell from the pic.  If your camera is like mine, use the little flower looking button for close ups in fine detail, works great!

I would say a little lean also. maybe another 2 steps up. 1 may do it but you should stay a little rich just to be safe. How did it feel?

It felt ok, but I have gone out for a ride on it again and it has seized again.will allow it to cool and take it home. I had added 100mls oil to the tank as well as using the pump. maybe get pipe next?

Just kinda an obvious question, but are you running it with the fan shrouds on?  That whole seizing scenario isn't good!  I'd hate for you to ruin your new cylinder and piston!

Yes, the shrouds are on. do you think maybe the exhaust might be too restricted for this size cylinder? Maybe not letting the gasses out causing overheating?

Good!  That could be.  It did look like it was seizing on the exhaust port side.

Yeah, I'll check ebay and see what I can find. I am a sucker for ebay. I wont ride it again until we can get it sorted out.

This is the new plug, it was in when seized.

It doesn't necessarily look lean, but the plug temp may be too hot.  Maybe try running one number higher (colder) on the next plug and see what it looks like.  What plug are you running now?

Will do, if they have them in stock. if not, what would be the next best?

Your local store should be able to cross reference that NGK number.  Your looking for the BR8HSA.  They didn't have them in stock when I got mine either.  They just cross referenced and I got some Champion plugs of the same size.  They are cheaper than the NGK so I bought all of the ones they had in stock for plug chops.  I'm still trying to exhaust that supply! ;)  There is a good explanation of what that letter/number code means on the NGK website.  It has to do with the thread size, length, temp. range., and some other things.
