If you're only looking for OEM performance (no special applications) your best bet would be to go with OEM parts.
As with any OEM parts, check bikebandit. Honda East Toledo, etc.
A full transmission will run you about $900 new. That includes main shaft, counter shaft, all your sprockets, washers, clips and rings.
OR Check out EBAY. People sell parted motors all the time. You can likely get a whole transmission for around $200. There's a little bit of risk in this. Make sure you get extremely high quality photos and check all contact surfaces for any wear and tear.
Or you can just replace the gears that are grinding. Most likely two sprockets and a few washers/spacers and possibly a selector. Run you about $350 total in parts.
I would go the ebay route.
