Any one interested in the oiling mods I did?
Here's my reasoning....I slotted the area that is normally drilled by the main feed and cam feed...basically I turned the two round holes into a slot. Then, I kept slotting an additional 'hole size' in the direction of rotation...this was because of YR's timing posts and also because it made sense in that it followed what's going on at the #1 main due to the added left galley feed. Also, because it is a fairly symmetrical slot... XX degrees off center in either direction. All this would not mean much without the bearings being slotted because they only have a single 1/4" hole.
I agree, the top half of the bearing is less loaded but my gut tells me to keep the bearing well supported. I've seen the small blocks that were made with the big hole so it has to be OK but it doesn't seem ideal. I dunno.
