I'm posting this because I never seen anyone else post this method on here.
1. I removed my clutch cover and took out the plastic gear then removed the pump.
2. I didn't have a block off plate, so I used the rubber plug that's in the water pump outlit and jammed it in the hole where the oil pump sat ( it fits perfectly. Nice and snugg..almost like Yamaha was thinking ahead for us lol..
3. I then took the rubber cap off the now not used oil pump and that fit perfectly over the water pump out lit..
Has anyone ever done this..it seams super tight.. Does a lot off pressure build up in the case . will it blow out?
I did this cuz I lost the pump cover and it looks cleaner...should I just bolt the pump in its place?
