G'day Owain.
Good to hear your going for new pistons. What oversize are they? The old ones would take a lot of work to make trophy's let alone make good for re-use in your motor.
Minto. First you'd need to ship the bike over for the Berry Bike Show https://tinyurl.com/y3jd7spq I'll take good care of it, promise.
Cheers

Cheers again for the advice everyone. I left the cylinder and new pistons (+0.060") with the machinist today (SEP in Derbyshire...Not the one who did the orignal tight bore). It'll be honed to 0.0045"ish piston clearence, hopefully will pick it up and reassemble this weekend. Hopefully the next time these pistons will off will be when the cylinder will be lined and taken back to std bore!

I think I'll leave the old pistons in a box in the garage instead of on my wall. I don't want to be reminded of my appaulling running in procedure  *lol*

Don't be hard on yourself - seems to me to be more a conflation of other issues than purely a running in matter.
