Boring chainsaw one piece cylinders is not very common and it
rather expensive ($500)
Larger chainsaws, for race saw applications, sometimes have the
head machined off and a new head made. They are sometimes bored
and or sleeved.

yah I have had a lot over bore by u.s chrome and millieum and
max power. I have bored the 166 sachs and put a 3120 big bore
62mm in it and it was a two piece herb gingras got it now I got
some 272 pistons 54mm getting made too at the same time as my
the big 70mm 090 pistons getting done. m.v used too put 288
cylinders on the 272 bottom and ran real strong I thought it
would be easier to just bore the 272 cylinder instead and make
it a 5 cube saw
