    Where exactly would you grind the followers to change the length? The only way I've ever seen it done was by sawing them and rewelding or by welding the roller axle hole shut and re-drilling it. I suppose you could grind on the platform that lifts the valve but it is harder near the surface, Maybe for my half a degree that I decided to ignore.

    Bob Nichols once told me he had only seen one guy who ever did it right by heating and bending the cam follower. He said it was Don (Dan ?)Iverson another Bonneville racer. I like the military floorboard.

    I assume the set up JG made for grinding, went with the company to the new owners. maybe John Bivens knows about it, they worked together at that time.


    I would think Jim Mosher would be helpful with advice , to support the sport and the old Indians

    Welp the Buell oil pump from Fleebay is going to move way too much oil. So I've changed to a early evo Sportster oil pump With a portion of the feed gear rotor ground off and replaced with a spacer. It will be driven off the rear cam. Just starting to design the adapter.

    Idea I thought, was to use late chief slotted cam shafts, to drive 2 slotted matchless pumps
    thats if chief shaft dia is same as SS

    Sounds like a great idea except I need one of the cams to turn the ignition pickup and there aren't any Matchless pumps in New Mexico that I know of. And most importantly I already have an early Evo Sporty pump in hand. Scout and Chief shafts are the same diameter just different lengths. Chief are longer so can be cut into Scout length. The gears are even the same after you grind the lobes off and will work in either location you might have to add the extra marks.

    Hey dusty, you have a fellow Bonneville badass living in the same state as you. I have crewed for him and his sidecar. Wally Kohler is his name and he is down in la Luz near alamogordo nm. This "sidecar" had set records over 235mph. Wally owns numerous records in different classes. Just fyi!

    Yeah that Indian is an amazing piece of art. I have talked with him numerous times about it...camped next to his rider back in 2018.

    Started slotting the drive gear on the sporty pump. Strangest setup I've ever made. An end mill would polish it a little This was actually pretty quick. I started grinding the teeth off and something broke in the lathe power feed so I'm headed in the lathe repaiir direction next.





    Presto a .170" X .330" slot.

    Band aided the lathe back together maybe good enough to last until the new parts get here. But for sure long enough to get rid of those pesky gear teeth and make it fit into the adapter.

    I now have a Sportster oil pump that drives by a slot and tang.

    This ought to make all the pristine parts restoration crowd cringe. Grinding the end off the front cam to get to the distance I need to grind the tang that will fit into the slot in the timer drive I'm going to make.

    Got the drive tabs ground onto the cams and the cams in place hopefully for a while. As far as I can on the adapter until I can until the timer is built and I just started making the shaft. If I was going to do anything with the bike other than race at Bonneville I would either shorten the pump or drive it with a worm gear and hang it to the bottom like the Sporty it came off of.

    Started building the timer.
    A piece of 1" plate from the scrapyard and some quality time with a hole saw yielded this blank


    A little time going in a circle yielded the basic shape.

    Got the bottom of the timer cut to shape and the guide plate relief cut in the side.

    Centering the A-dapter plates (as Johnny Cash said). Once they are centered I'll drill holes for the pins that will keep everything straight.

    Getting a little closer to shape. The timer rides on the outer bearing race that sets proud of the adapter with a slot and guide plate on the outside The reluctor mounting plates that allow each reluctor to be time seperately are made but the photo didn't come out.
