oil build up in crankcase on commando 850 bleeding through cylinder barrel gasket

When putting barrels over piston/rings is 4 hands is better than 2, I have VW ring compressors but sometimes just as easy to have someone hold and lower the barrels and the other person closing/pushing the rings into the right position as I found using the ring compressor the bottom ring pops out before going into the bores then after fitting have to remove the ring compressors so find it easier to use my fingers and a small screw driver and a friend, even using ring compressors is still good to have extra hands to help.

My friend Julia helped hold up the Barrels staddling the bike reaching down to hold them whilst I slackened off the 2 clamps , she / dropped /pushed down as instructed perfectly and I removed the compressor clamps. She was 62 , now 65.

Looks like a good tool and I want one! But you still have to deal with the back-side circlip when removing it with the barrel still attached. I suppose with right-angle pliers one could possibly extract the dirclip(s) but the risk of dropping one into the case is ever present. How long would it take to fish that out again? Even a case stuffed with rags.

Ok, I have a few minutes to explain.
Step 1 Remove the cylinder, up off the pistons.
(Perform your gasket remediation)
Step 2 Remove the wrist pins however you like. Remove one or both circlips, your choice. Remove the pistons. Re-install the INBOARD circlips.
Step 3 Install the pistons in the bores by compressing the rings with your fingers. (Been doing it since I was 7yo, not difficult)
Step 4 Put the cylinder in place, temporarily supported at an appropriate height. Line up rods, slids em in, circlip in.
Drink beer, and reseal your gasket.
