Just finished a ride the other day when on the next morning I saw a small puddle of antifreze under the bike. Upon closer inspection, it seems its coming from around the #2 cylinder exhaust studs that bolt the exhaust pipes to the block. The bolts/ nuts were a little loose, so I gave them about a 3/4 turn. Hopefully that was it, but any suggestions would be appreciated! By the way, its not blowing any white smoke/ steam and the oil doesnt seem to have any water mixed in

It may be dripping from the exhaust studs, but is probably coming from elsewhere.  Check the water pump, thermostat housing and radiator hoses for the leak.
The most expensive things you will purchase, are those things you would not have needed if you had listened and obeyed.

Most likely o-ring leakage on the metal tubes. If you look down in the valley of the engine you'll probably see a little anti freeze puddled there also.

I had the same thing happen and was worried I may have cracked a head. Looking higher up, I saw it dripping from around the hose at the thermostat housing on top of the engine behind the radiator. I snugged that clamp up and no more leak! I had to drain the coolant and slip the hose off the upper right hand radiator extension. That was a bitch. Then I loosened the top mount and rotated the radiator enough forward that I was able to get a long quarter inch extension with a universal swivel and socket and tighten the clamp up.

Tight hose clamps are good. 

But a lot of times, after a bike sits in the cold for awhile, it will leak from a hose a bit on startup/heatup, but then everything expands back to normal and no more leak.  Until the next time it gets frozen.

You check your reservoir, that may not look like you lost much or any coolant.

Top radiator hose clamp tighten it and your leak will disappear.

"Hopefully that was it" really?

If coolant is in the combustion chamber you would have much more serious problems.

As was said it's leaking up higher and dripping down.

I must have misspoke. That was my fear! But there's no water in crankcase and no oil in cooling system.  No steam blowing out of exhaust. Will be tightening hoses later today

Had this same issue last year check the thermostat hose clamp
