I have making a search and I'm not founded the information about this question.

it is possible to oversized ( 0.25 mm ) the stock h22a4 cylinder?

and what is the reliability?

 

itd be risky, you would be getting very close to the frm sleeve. you would have to sleeve the block

negitive

yes it can be done... safly with the right machine. look into Jim Justice if you want it to be done correctly.

and you are right it dose get close to the end of the FRM liner but there is still some there.

i have mine bore out .25mm been running strong for 5k miles so far no problems.

 

yes you can. they have an oversized Type S piston for this reason.

 

thanks for the quick reply!!!

 

.25 mm over is the service limit for the FRM sleeves, iirc.
