Noisy Crank Bearings?

I just got my 86 Spree running. It seems to run pretty good. Starts well, and runs up to 25 MPH pretty well. However, the engine seems to be making some pretty loud bearing noise. I removed everything from the end of the crankshaft so I was sure I was not hearing any bad bearings in the drive line, but the crank is still noisy. The engine has good compression, but the crank bearings are definitely making noise.
Is it tough to replace these?
Do I need to replace the crank, or can the bearings be removed from the crank for service?
Are the parts hard to find?
Any ideas would be helpful.
Thanks,
Scotty

OK, here is what I found out so far. I split the case this weekend, and found that the crank bearings were definitely the problem. The rod end bearings look to be in fine shape, just the main crank bearings.
The cylinder, piston, and rings look like they are in great shape. I guess that explains the good compression.
Where is a good place to get these bearings?
Any ideas?

Local bearing shop could probably match em up.

Update:
Local bearing shop was able to match up the small bearing $6.25. Large bearing is non-standard. Ordered from local Honda dealership for $20.
Will arrive in a couple of days.
Should be reassembled a day of so after that.
Will send results at that time.

Those bearings are standard as follows:
Big #6004 (20mm/42mm/12mm)
Small #6203 (17mm/40mm/12mm)
(ID/OD/thickness)
Honda charges 1 arm and 1 leg per bearing, I can't understand why such the markup on some parts while others are almost free. I mean, a $2 petcock costs $50, while a piston only costs about $30? Come on.
