I had a set of barrels sleeved a few years back and they sat on the shelf with new JSM pistons for maybe 5 years until I decided to use them.
They have only run for 2 or 3 race meetings, the last one being Pau Arnos in Sept 2019, I got helicoptered out of there so it has taken a while to get back to doing things.
Recently, I pulled the motor to refresh it before my hoped for return to the track.
I am planning to use another set of barrels anyway, but I reckon the sleeve rotated. Only one of the two by the looks. My first reaction was that I was lucky not to have shrapnel everywhere, but comparing with other barrels I don't think the correct location of the cut out section is critical for the combination of my JSM Carillo long rods and 80.4mm short stroke crank.
But I can't think a rotating cylinder sleeve has no consequences.
I am wondering what I should do with them, if anything. Anybody experienced this before on iron barrels?
