which oil pump?

[philbert]

Hi folks,
just checking over my new to me 31k ypvs.
in the box of spares is a 1AO oil pump that appears to have seized at some point.
checking the bike its fitted with a 4l1 pump which i assume is wrong!
can anyone tell what pump should be fitted?

Thanks

There are different markings on the pulleys

350 can be 4l1 or 1M1

Its the internal gears that differ

I'm sure even some had 1A0 too

Should be a paint dot on the bottom pump screw

Yellow is 350 and red is 250
