I am new to the savage and I have a question on a oil leak. When i first got the bike it never leaked oil. I changed the oil and since then it has developed a slow leak. Its not the drain bolt or the oil filter cover. Is there a known spot for these savages to develop a leak? Any help is appreciated.

If the leak is from the bottom.....make sure the footpeg bolts are tight.  The bolts go clear though the front of the engine, and if they get loose the middle seam of the engine can leak.

Also if your sprocket nut is loose, oil can leak from that shaft....be sure to check that as the shaft can be damaged if the pulley is wobbling around loose.

Then it's the footpeg bolts... It'll seal back up when you reinstall the engine...

Why is the motor not in it?

There are a coupla good questions..

Drain the oil, you can close the gap with a piece of all thread and some nuts and washers.
