ET: Engine (Twin) Modifying the Valve Lifter Mechanism on 1,000 cc Engines

[Michael Vane-Hunt]

Bruce. Uses a cable instead of a rod.

I knew that I had a picture of a different approach. I don’t know who did it but it looks like a simple way to avoid the knitting needles or having to hinge a rod. Would it be easier to make oil tight?View attachment 51486

Apologies for being slow today, but how is that different from standard?

Hmmm, cable instead of rod - would that be desirable for the connection of both lifters on cam followers ?? There is a lot of offset in the positions of levers due to cylinder offset on twins which means there is a side pull in the original spoke linkage. You´d need very sloppy holes in levers for coping with poor alignment of levers when having a solid rod. So a cable would do nicely - with safely brazed ends for pins and clips on levers ??
I did not accept that matter as is and made a longer front lever to bring it up to alignment with rear lever. So a support on the outer end of the long lifter spindle was fabricated, not shown in first photo. Second photo shows alu support bracket fixed with 2 Torx countersunk screws.
