Hey everyone!My dad purchased a 2002 CRF450R built for road racing about two years ago now. We started it once, then he tore it apart and it has been sitting on a stand in pieces for two years now. He says that his only hold up at the moment is a brass (maybe copper?) washer behind the water pump, being that it is backordered due to the bike being an early production model.
1. Is there a difference between early model CRF450R water pump seals?
2. If so, can one be CNC'd to OEM specs rather than waiting 7 eternities to come off backorder?
3. Does anyone have the part number for said washer?
After some more research, it seems like there is a 6.5 or 7mm copper washer? Just in case that helps jog anybody's memory.
Thank you for any help, I have loved supermoto since I am a kid and cannot stand seeing the bike sitting there every time I visit my dad.

Welcome to the site !!

Any year Washer will fit , so pick any year 450R from 2002-2021 , and whatever one you can find in stock , order it ....

The 6.5 washer is for the Oil Drain in the lower right corner of the ignition cover ,,,, So only worry about the 7mm washer
