Motorcycle Repair: loss of power, vt500c, honda shadow

Question
i have a 1985 honda shadow vt500c with 10,000 miles.  a few days ago i passed a car going up hill at 60 mph, and about 3 minutes later i lost power.  i was lucky enough to live at the bottom of the hill, because the bike wouldn't go over 20 mph.  ran perfect since i bought it a year ago.  one exhaust feels fine, but the other (front) does not get hot and it alternates between blowing out and sucking in at idle.
thanks in advance-

Answer
Hi Barrett,

The problem may be ignition or fuel related. I cannot tell from the information provided. I would need to perform a few checks to accurately diagnose the problem.

Check the air intake for obstructions. Check fuel level.

I recommend having a local tech check your VT.
