Cannot recall what size ( probably 8 or 10 mm), but it is righty tighty -lefty loosy, so CCW to answer your question. Make sure the bike is in gear and remove the two bolts. Slacken the chain tension via loosening the rear and it slips off. This of course is after removing the 2 screws holding down the sprocket cover. Use threadlocker when installing new one. Drive a nail into garage wall and hang old sprocket!
BTW, Your model has two bolts holding the sprocket not the center mounted like I think you are anticipating.
I have assumed the 1100 was the same as the 696. When I looked up the sprockets, they were the same part number, but the reference I used may be incorrect.
Sometimes with the larger center nut, an impact gun helps to get this off. If you dont have one, try to break it off with a breaker bar. You need leverage and a quick motion downward to get it loose. Make sure the bike is in gear.
