Can you stand a 700 Yamaha 4 stroke raptors up during transport or will the oil leak back into cylinder head filter?

Yes, you can stand the Yamaha 4 stroke raptor 700 on its end during transportation. The oil filter is designed to prevent oil from leaking back into the cylinder head, even when the bike is upside down. However, it's always a good idea to check the oil level before and after transporting the bike to make sure that no oil has leaked out.
