Piston knock


My 500 (with 43,000 miles on the second speedo, so total mileage is unknown) is down on power and has recently started the get a bit of piston knock/rattle. I have a new oversize piston ready to fit but am wondering (dumb question alert) if it is possible to lift off the head and barrel with engine in frame? Has any body done this? Thanks.

Nope, haven't done it. I imagine it might be hard to get to all the bolts.
