I’ll take them Ash if that’s ok, just add them to the cover for when I pop over. Not knowing what state my barrel liners are after 30 years I was thinking it may finally need a rebore, either that or fit some 550 barrels but that involves widening the crankcase opening IIRC
Ken, if yours is a later 500 the 550 cylinders may go straight on, or cheat and bore the 500 to 550 pistons
I don't like the 550 engine in a 500 frame Graham. The bigger clutch housing interfered with the rear brake lever, tried it before, didn't like it so went back to the 500. It's far away from standard yes but it's all that era Honda parts, I just prefer to upgrade the stuff Honda should have got right in the beginning Always thought the 500 liners wouldn't bore out to a 550 piston Bryan. Well not safely anyway. My engine number begins 20249** not exactly sure how that sits in the engine number range.Not sure if first over will be enough Ash, most likely would be before buying I'd prefer to see and check first, at 3rd over your pretty safe it will clear at that.
