Yeah, it could certainly contribute to those problems, as well as the valve guide dropping out of the head. Ask me how I know.

You can check it by having the bike running and CAREFULLY putting your hand down there around the exhaust and feeling for hot exhaust coming out, without touching the metal bits. Best to do it when the bike is cold. You also might try blowing some smoke in that area and seeing if it gets blown away from the exhaust. This is not to be construed as a recommendation to smoke.

I have only heard of doing this.

Take a deoderant spray (Ban brand, something white when it sprays)

Spray in on the bike in the area that you think you might have a leak.

Start the bike and let it run a little the area will turn BLACK where there is a leak

Just spray wash off the the rest of the white deoderant, comes off easy!!!

I guess I ought to act quickly when i'm testing for it... the engine tends to warm-up quick, especially here in FL

Well, it shouldn't take much time to feel the pulses if it is a significant leak. They tend to warm up quickely everywhere. I dunno about causing the vibration, though. More likely the vibration caused the exhaust leak. You might want to look to other causes for that.
