Had water in my 2001 Sportsman 500 HO recoil starter. Needless to say the flywheel and bendix gears are all rusty and covered in crud. Is there a quick and easy way to clean the rust and crud off like spraying them with carb cleaner or WD 40 without ruining anything behind them? The bike was starting ok with the electric starter prior to the fix on the recoil. Thanks in advance.
