If you are talking about the oil you drain from the hose under the center of the engine and after changing the oil filter, about 3 1/2 quarts max, that's counting the 1/3 to 1/2 quart you put into the new filter before installing. I would start with 3 quarts in the oil tank, put back in and tighten dipstick, start up and run bike until it is warmed to normal operating temp and then shut down. Then with it on the jiffy stand unscrew your dipstick, wipe clean and reinstall stick tighten. Then remove stick again and check level. Ideally you want it about half way between the add and full line. If you are talking about what they call the transmission oil, the one that you drain by removing the plug on the bottom of the left side cover. It takes 32 oz. and is checked having a friend sit on and hold the bike up straight and removing the cover over the clutch (the big round one on the right side of the left case cover) the oil lever when full should be just a hair above the bottom of the clutch gear.

Check for any damage to both belt sprockets. Make sure you are not over tightening your belt by using a belt gauge. Make sure your belt is properly lined up straight and not rubbing on the edge of either sprocket as well. Finally make sure you never over fold the belt before or while installing as this could also damage and severely shorten the life of your belt.

First thing I would do is check and make sure the battery has a good charge. If it is fully charged, I would check fuses and relays. Then I would want to check to the make sure the engine turns over by removing the spark plugs and put the bike in high gear and see if you can coast it (i.e. down a hill, have some one push you while on it) if on a jack so the rear wheel is up in the air, you can rotate it by hand. If all that checks out, I would want to pull the starter and do a bench test on it.

You push the button on the key chain fob.

Wiring is hard to diagnose without the bike.

It would seem to be a wiring related problem. Check all wires around the speedo and where they go around the head stock. Also, check for poor earth connections.
