that part came out in year 00 better known as recall plate.
it was suzuki way of fixing oil starvation at pump after rod bearings 
started to go bad because they were using sv400 cases.
99 cases have another plate right next to it.this first 99 cases are direct 
from sv400.later they added little to case in casting proces but not 
enough.reason for that recall plate.in 03 they made new cases and closed 
without that plate you are risking rod bearing failure due to pistons 
pumping oil away from pick up.
