Do not use a torque wrench on this type of cover that will be taken on and off many times. You are just going to strip out the aluminum threads. Just use the straight handle drive like a screw driver. Run all up snug crisscrossing. Do a little more and you will fill the gasket starting to squeeze. Do not crush the gasket flat. Drive it around the block and give it another snug just to see if its loose. Keep an eye on it and check back in a week. Bet you will find it snug and once from here next time you need to open it you will need the little 1/4 breaker bar handle to get screws to pop loose

so you know, 108 in/lbs is snug then a 1/4 turn or so. Believe me it is fine to use a torque wrench set to the correct value. I do it all the time and never have a problem.

Leak
This should not make any difference since if you get it right it will not leak but were is your primary oil level with the bike on a level surface and held up straight. It should be just touching the outer edge of the clutch disk down at the bottom. It should not be up at the top edge of the opening.

Few thoughts.
1. Sure you got all the oil off the cover before putting it back on? If you do not it can give the appearance of leaking until it all runs out forward of the seal area
2. If you pull it back off clean it off and without gasket put 3 screws in just about 3-5 turns and slide the cover up to to primary cover. While holding it at the edges and pushing in see how much rock you have. I had a Harley replacement cover (made in China) that rocked a 1/32. Since I had come by it on e-bay I took a piece of 320 emery cloth and taped it on my Sears' cast iron saw table and flattened it out. Took me an hour to break thru the chrome but once into the Al it got flat.
3. Just use one small drop of blue locktite from a toothpick if you must. I do not use any. I just torque with my torx socket on a straight handle drive and when hot check it it a few time. Never had one come loose. Since I do all my work I keep an eye on thangs. Fixed many striped out holes because someone poured locktite all over it and had brought the soft Al threads of the primary out with the screws.
