The issues are with a bone I broke in my hand several years ago, not a big deal but I thought it was worth looking into.
About the F4i perch, in theory, closer to the bar makes it feels lighter correct? Does your Suzuki perch have better leverage?
What about something like a Pazzo?
Ahhh, that does make a difference.
My situation is different.
For me it was all about ergo fit.
The stock perch and lever forced me to reach for it every time.
Not only was that not good for track days, it also has your hand working less advantageously because of flexing from at or near full reach.
The F4i perch moved it in a bit, but nowhere near enough.
Then I put the CRG on it, still have it on, and at position 1.
While I normally 3 (middle) finger clutch, I can do 2s, but don't like it as well.
Keep in mind that I do not have strong hands at all, not only am I a pinner, I'm near 65 too.
As an experiment, try adding a bunch of slack to your clutch, such that the lever is not doing anything until it's back some.
Play with the "how much" a bit, and see what you find.
You may find that a revised lever position solves your issue.
Expect to get some clutch drag when you do this, something that can easily be skirted about for a short experiment.
To a degree, you can tell even if the bike is not running.
This way you will know before paying for parts, whether they will help you or not.
Other levers that are highly adjustable will serve just as well as a CRG.
The CRG gives about an inch of adjustment range from 1 to 5, as measured at the ball end of the lever.
The stock 919 lever is awful from an ergo point of view, at least I feel it is vis a vis what I want.
I haven't tried the Suzuki perch and CRG lever yet.
I eyeballed things and gambled and bought the parts.
I know I can match the 919 cable end without much difficulty.
To be honest, I expect the Suzuki perch and CRG lever to offer LESS leverage, not more, as the clutch design is radically different.
Anyway, try my suggested experiment first.
The cost is right, that's for sure.
