I just got done drilling and tapping the radius rod bolts for grease zerks and am now trying to figure the best way to add one for the ski pivot.I have new bushings and collars for the ski pivot but want to add a zerk to make it easier for servicing.To those that have done this what did you do and where did you put the zerk?

LIFE MEMBER ONLY ONCE!!!
what one member did before was take a long bit and drill from the top of the spindle all the way thru to where the bushings sits.The spindle is basically hoollow,so only place a hole is drilled is the material above the bushing.Then he somehow added a grease zerk on the top ot the spindle.Pump it all full of greaser and it will find its way down to the bushing thru the hole you drilled.I have not done it,but have put zerks on the radius arms.I grease my bushings once every year and clean out any rust first where the bushing slides into the opening on the spindle/saddle bolt location.

Just copy how polaris has done it for years. http://images.powersportsnetwork.com/fiche/images/Polaris/2001/Snowmobiles/6424_6087a013.gif
The way Polaris does it by mounting it on the back side of the ski leg/pivot wont work on a Yamaha,the rubber bumper is in the way.I ended up drilling a hole on the outside of the pivot on top,it's kind of a pain to put it there because there's weld there and it's a bear to get the hole drilled straight.I also drilled two holes in the new collar right where it rides in the bushing.I'm not sure if the grease is going to get through but here's hoping.
i did mine through the bolt head. drill hole to the center, small drill, then drill hole for drive in grease fitting in head of bolt. Drill into side of bolt to intersect with the other hole in a few spots. Then drill a couple holes in the collar in line with the side hole in the bolt. The reason for a few holes, is, when you tighten the bolt sometimes the collar is not lined up with the hole and the collar is pressed against the hole in the bolt and blocks it off. first ones I did I had to make sure when installing skis that the single hole was lined up perfectly with the collar hole.
I purchased ski and radius rod bolts for my Indy wedge years ago that were drilled hollow and had a grease fitting screwed to the end. I think I got them from Maravian Sport Mart or Rec Leisure here in S.E. Michigan. Neither have a website but I did find a company in Ontario that sells them...

I was going to do mine this way too but wondered if drilling in as far as the short drill bit I have would be sufficient.The drill bit I have now will reach in as far as the first bushing and I already have holes in the new collar for grease to come out through,surely if grease got in that far it would work it's way over the the other side.
