cylinder honing
my girlfriend just pulled apart her B20a, and i was talking to a friend of mine and he was saying to give it a bead hone while the pistons were out
so, i think its an 81mm bore, but i'm not sure where to get one, the only place i found has an 83mm bead attachment, but had like 6 different abrasives on them, i'm pretty lost here, anyone shed some light on this?
this is all i could find
GB and GBD from Brush Research Manufacturing
thanks

Some new OEM (factory honda) rings would be a good idea too.
If the motor was burning oil or smoking & has a lot of wear, I would inspect the cylinders to see if the setup needs to be bored .25 over per the helms manual specifications.

Yeah use the 83mm hone. I've used an 89mm ball hone on an 81mm setup and that worked ok too.
Just remember to oil the hone with 30wt oil and move quickly. Don't stay in a cylinder for more than 10 seconds. After 10 seconds remove the hone and check the finish on the walls. If it is good then move to the next cylinder.

its a JDM B20a out of a 3g prelude
she got the motor in and is rebuilding it, new rings, new seals, all that good shiz
complete rebuild, but as we have never had it running, i'l burning is unknown, but everything looks good in it on visual inspection
and is that a good hone?
what abrasive?
or what do y'all use, or is it really necessary to even do it at all
