I completed a big bore 100cc. I went for a test ride after many days and hours of endless mechanics. I get back and its leaking from my tranny compartment a dark thick fluid. Appears to be oil. From my tranny compartment. What now? Please help.

Not sure what you mean by the "tranny compartment". R U referring to the GEARBOX (where the clutch and rear axle are), or just to the area behind the CVT cover? I'll guess you mean the CVT cover.
Then pull the cover (NOT hours or days of playing mechanic) and see if the leak is from the seal in the front (crankshaft) or the seal in the back (clutch shaft) ..... or ...............
from around the new jug you just installed (I'm guessing THIS is the culprit, since that what was just fooled around with). Oil from the jug might be dripping down and appearing to come from behind the CVT cover, though usually it just drips down and appears to come from the bottom of the plastic engine shroud.
But step 1 is the easiest one - take the CVT cover off and make sure it's not one of the 2 seals. If they are OK, then remove the shroud and you will see for certain where on the new jug/head the leak is. One common source is the chain tensioner. Another the paper gasket between the jug and the crankcase. Obviously you would want it to be the tensioner before the jug, since the fix is 1,000 times easier.
And for God's sake don't go through the rest of your life sideways like that!
