I have a 1983 V65 Magna with 20,000 original miles. It runs smoothly and seems fine. A person who is unfamiliar with these very agile bikes would not realize that there is a problem. It simply lacks the quickness that it should have. The compression checks out fine. The carbs have been adjusted and synced. Ignition timing is fixed and cannot be changed. Any ideas?

Is it fully stock - air cleaners, exhaust, etc.? If not, list any mods.

Have the air cleaners been replaced? Dirty filters will limit power.
Are the valves adjusted to the correct gaps?
What color are the spark plugs?

This may sound funny but was it sitting around for a while. . I had a similar problem turned out that mice made a nest in my pipes once I cleaned out the nuts sticks

Dirty carbs can cause an engine to run "fine" but have loss of power
Agreed. One thing to check is pull out your jets, check all the little side-holes along their length. Use a small fine wire to ream them out. I've often found that a bike runs "fine" with all but 1-2 of these holes plugged up, but lacks correct power. Just guessing, but given all what you've eliminated, might be worth a try.
