After post a question about one of my head bushings on my XS1B I receive and answer and several great suggestions from 5twins, XSRod and Tom Graham on a modification that seemed to me to be a pretty good idea so I decided snag one of the picture links from 5twins (I hope you don’t mind) and post a few pictures of the progress I made on doing the mod on my own bike.
This is the pisture from 5twins comment
This is the way my original tappet looked
I did a lot of searching on the internet for the Elephant foot tappet looking for the best price. Then I remember from the days I had VW’s that Claud’s Buggies was not far from here. Claud’s Buggies in now called CB performance and they have a web page. On the web page I found the Elephant foot adjuster I was looking for. It was part number 1518 and it was $32 bucks for eight of them. Such a deal! The next day I went down and picked them up. It was $36 bucks with tax and all.
Next disassembled one of my rocker and measured it with a caliper to get the stand-off on the original tappet since it was still set for the valve stem it was on. The stand-off was .164 thousandths so I figured if my modifications made the minimum stand-off around .100 thousandths I should be good on all of them. My thought was I would just copy 5 twins picture as close as possible and then measure it to make sure the adjustment travel or stand-off was within range of what I needed.
So then a Just ground each rocker to accept the 8mm elephant foot adjuster and tried not to get it too hot from grinding. I ground it kind of like I sharpen drill bits. Just quench them in water often enough so that they don’t get hot. For me that means every time I look at it I quench it. That’s a lot of looking and quenching.
I took several pictures during the process
Since everything was going so well I decided I would try to match the weight on the adjusters by cutting them down and Re- slotting them for the screw driver. I clamped them between two pieces of wood and cut them off with the Dremel cut off blade about two threads in from the slotted end which was about 1.062 thousandths long measured with the caliper end to end. Then I beveled them with the grinder and re-slotted them to match my Snap-On screw driver. I figured it was a typical screw driver. And probably the one I would use when I set the valves.
With the quenching and all the last thing I did was shot them with WD40 to displace the water that might have gotten between the foot and the ball. I didn’t want them to rust.
Well that’s it for now I hope you found this interesting
Thanks to 5twins, XSRod and Tom Graham for a great idea and a fun mod.
