Oil injection

[wideopen]

Removed the oil injection from my 1996 90 yamaha. Do i need to plug the hole on the reed plate that the oil lines went to? And on the middle carb there is a place for a line on the back think it was a oil line from the pump, and a place for a line on the intake dont know what to do with them all on the left side.

Yes plug all hose ports or will air leak on intake and make engine run lean.
