Took clutch out I held against it using actionmans rag trick! How do you hold against the centre bit to get the big nut off without breaking the fingers of the basket
The camshaft and rockers look ok to me
What are all these wee holes? The piston looks brand new
How do I tell if it's a standard piston
The bore feels ok with no scores should I get it honed and fit new rings. What should I check while its apart how do you see 5th gear what about updated oil pump fuckin hell sorry that's enough questions!
Pitting is normally a sign of detonation, id like to have seen the old piston.
May as well pop out the valves & check the seats, and fit a 3AJ oil pump 1988 & newer (don't limit your search to Tenere`s) all XT`s from 88 onwards all used the 3AJ pump.
Mezo.

Googled the part no. on your piston, looks like you have a wiseco forged piston.
The 09700 part of the number is the bore, 97mm, so it's had a +2mm rebore.
Your next question should be why was it detonating (pinking)?
It might be worth checking the squish clearance (the distance between the top of the piston & the cylinder head) when you rebuild it.
They are from a foreign object bouncing up and down at 5000 rpm. Could be a small screw or something.
Would have also damaged the piston, hence the new Wiseco and rebore.

So I stopped worrying and lo and behold, things did get worse!
i know Eric does, here it is.
