i know i like to use coarse stones to get a good quick seat on my later model hondas. 120 grit.

always make sure it is lubed though, and i always hose off the cylinders with brake cleaner and wipe the cylinder walls with rubbing alcohol soaked paper towels until they dont pick up any more dirt/shavings. then wipe em down with wd40

I agree! 320 is hard to beat. Try to put a 30 degree up and down on it, then scrub it with Scotchbrite to remove the grit. Works like a champ ;)

best thing to do is get a honer....lube up your cylinder and go at it, just a few things, don't stop the hone in one place while you are honing, keep it moving. and it does not take but a minute or 2 to usually do each one, some parts stores rent them.

OEM rings are chrome top and cast on the lower. I would use 320 to help the rings to seat.

What is the proper "grit" for honing cylinders for use with "standard" rings on the E series engines? The service manual for the EF1 says to use "fine", but how does that translate to 280, 320 or 400 grit?

A generic "performance" engine building book I have recomends 400 grit for cast-iron or moly rings, and a more coarse grit if using chrome rings. What kind of material are the OEM rings made of?
