think the small end is called a roll pin in the Jab book. I cannot recall an actual roller bearing in it, the roll pin goes straight through the piston aluminium body

Have a perfect No 2 piston and con rod, also rings and barrel if reqd and head, will need do coking/ clean up
As apart i would fit new exhaust valve and rings


Its easier to take off the con rod from the crank rather than trying to get the piston clips out, only 2 bolts and the piston and rod is out

Got the bits from Kevin at the rally, new head, piston, rings , four exhaust valves and collets £653.20 which is less than I estimated, not back together yet as on the new head after I had lapped the exhaust valve in I found the inlet valve was not true,(probably damaged when the exhaust valve let go, it only take one hit) so a phone call to Kevin again and he is sending one out to me. I'm having to wait for an engineer at a local motorcycle shop to hone the bore to within tolerances for the new piston.
