1996 Bandit 600

[97SierraMN]

Just wondering if anyone on here knows much about motorcycles...bought a bandit 600 last September with only 5400 miles on it. Ran great on the way home but it had been sitting for a while before I bought it which rusted the tank and therefore messed up my carbs. Brought it to the shop and had the tank creamed and carbs rebuilt as well as the pet**** rebuilt. The bike runs great and I changed the oil on Tuesday. I used synthetic Mobil One bike oil and when I was done the oil was right at the full mark. Now a couple days later and after riding maybe 35 miles the oil is overfull... I don't seem to be losing gas and the guy from the shop said gas wasn't in the oil before either so I don't know why it would be now. It sprinkled one night but I doubt that water would have been able to get in there. Also the bike runs great and starts right up even in 35 degree weather.
Any suggestions as to what I should do? I just don't want to hurt the motor by running it with the oil overfull. Any help would be appreciated :cool:

does the oil smell like gas? you have to watch the levelness of the bike ( make sure its sitting straight up). was the oil a synthetic oil made for bikes? if not the extra friction modifiers in the oil will mess with your clutch.
