Honing bores on a GL 1000 with pistons in place

[pablo2020]

I have had to remove the cylinder heads from my 1976 Honda Gold Wing Ltd due to a leaking head gasket .The bike has 28,000 miles ,the cylinders look ok with no sign of scouring and can just barely make out the original honing marks ,I was wandering if it's possible or advisable to re-hone the bores with the pistons in place and has anyone done this .

Main purpose of honing cylinders is to help new piston rings seat. Yours should be already seated, I wouldn't worry about it.

Actually a former neighbor rebuilt the engine on his old Volvo P1800 with nearly 160 thousand on it. Still had scuff marks from the hone from when it was built!

just put it back together, and drive it like you stole it.

it is fine.

Unless you have it apart and are putting new rings in, leave it alone. The rings in it are seated to the bores. Honing now again will just lead to more wear of ring surfaces as they have to wear to seal to the new roughened surfaces. No good comes of it.

Well as the saying goes "if it ain't broke leave it" , so thx for the replies and have been convinced re-honing not recommended or necessary unless putting in new rings etc.
