matt when i rebuilt my mag i didnt have the pump bearings so i used the sealed bearing from a mid shaft kit, its been in there for a season and a half
 
Yeah did both on my blaster, stainless C3's, i did pop some bearing seals out to allow oil movement. I used synthetic moto gearbox oil. Been in for around 18hrs so far no props. Haven't pulled anything down yet, will be doing a strip and inspect in winter to check how it's all doing. I saw one of ur flywheels the other day over here in oz, very nice work mate.
