The location & process is on page# 70 in the "little" Owner's Manual, at least for my '98 it is. The check bolt is on the right side case, just below the clutch cover circle. The "level is correct if it is flush with the crankcase lower edge (threads) of the check bolt hole." Hope that helps ya! The manual was never clear to me when using the check bolt as to whether the bike has to be upright like when using the dipstick or on the side stand. I'm assuming on the side stand.
