Re: melted piston..but why?
you aught to measure the height of the cylinder head, it should be 73mm or more. Much less and there's your answer. After that you should check the operation of the AEI. the capsule may be leaky, or stuck and innefective.

Scoff,

Re: melted piston..but why?

and liner for a used item and obviously sorting out what caused it in the first place,

After the other week when I removed my head I saw traces of det and could not get my head around it, measured it after a good think and it measured 71.3mm:eek: No wonder it felt livley at low revs.

Re: melted piston..but why?
The pics were taken last night just after I removed the head.
Today I have removed the sump and popped all 4 pistons and liners out.
Obviously no.1 piston is mullered, though the liner looks in suprisingly good condition and its not split.
The other three pistons are all showing signs of detination too. They must have got pretty hot as the part of the piston that rubs up against the liner say the 6 clock position looks like its been freshly emery papered, if that makes sense! I will get a pic up tomorrow.
Re: melted piston..but why?
i would be interested to see all 4 pistons ;)

Re: melted piston..but why?
I just noticed that one of the other liners is cracked too. This probably explains the slight water loss I was getting. The level would drop from max to min over a period of 2-3 weeks. I just presumed I had a tiny leak somewhere.
Also I have a spare 209, but the module nipple is snapped off. Is there any way of replacing the module?

Re: melted piston..but why?
dunno if this could be right by saying it could have been running lean? just a thought?
