Its easy just get the proper grit consult the helms manual for oem rings or call the ring mfg for aftermarket.

I've personally honed quite a few Honda and BMW blocks myself and never had a problem with ring seal. The only ones I would not attempt to do myself are the FRM sleeves. If you got a junk block or know someone who does then just give a try on that one try to get a feel for the speed (up and down) needed to get the right 60 degree angle crosshatch. 10 seconds should be all the time you need per bore. After hone wipe cylinder walls down with rag and water, then rag and soapy water and then finally dry and oil the walls to prevent rusting. Do not use a solvent (brake parts cleaner) to clean the walls after a hone.
