Naraku 'black edition' racing PHBG type carburettors.
These carbs feature oil and vacuum feeds for easy fitment on most scooters. The throttle slide is quickly accessed with the screw top, also the main jet is easily accessible through the float drain screw. The outlets either side of the throttle slide are breather pipes (not coolant pipes).

Yes these are suitable for use with oil pumps. Fuel is the biggest brass nipple. The vacuum is the medium brass nipple. The oil is the smallest brass nipple. The two aluminium nipples on the side of the slide are breathers.
These are designed for 2-stroke engines.
Yes but fitting non-standard carbs aren't always straight forward. You may find the throttle cable length will need adjusting to make sure the throttle slide is lifting all the way up and down. The air box will go over the 38mm connection, you may need to warm it. And of course you will need to set up the jetting.
This carb does not use the coolant lines. You can blank them off on the head using these caps.
