Decrease the length of the lever on the carb, leave the bars alone. Different year spirals have different lengths of pull, the lever will change the distance needed.
No matter what I did with the Linkert installed I was not able to get the throttle to go full open, just ran out of "push".
Ok, switched carb to Bendix, and have a "pull" spiral installed.
Same thing, not enough pull to go full open throttle.
So,
Since these are not Harley bars, rather Hellings bars with harley plungers p/n 56391-49.
Could the spiral itself be the cause insufficient length of pull? OR, could the plungers be incorrect for this mix?
Robbie, would you know the part numbers for the different length for various years of length of the spirals pull?
Thanks for any advice / help with getting this solved.
I am now just waiting on a throttle wire to arrive, since I screwed up the last one I had by trimming it too short..
George
PS, edit to add: I don't want to modify anything on the bars themselves. I thought of making the slot longer but changed my thinking. Certainly I have a mix-up of parts. and it's just finding the right combo.

George,
There are no "different length of pull" spirals there is just one of each direction. Are the cable spools installed correctly and not causing an issue? What throttle arm is on your carb? I'll measure total pull on a set of '49 bars I have to compare for you.
I had the same problem with my '52 Pan, it turned out that the after market wire wasn't stiff enough and it was bunching up in the outer casing, I bought a length of choke cable. which is a lot more ridged from a lawn mower repair shop. it fixed the problem
While shopping for "choke cable" I noticed that they came in varying thicknesses of inner wire. I had to use a micrometer to measure the cable to get the fattest wire for my application. Again, stainless MIG welding wire might work too, as It is tempered and designed to be pushed through many feet of lined housing.

Robbie, thanks for offering me to measure the amount of pull, that way I have something to compare.
George, apropos of nothing, I've been to Ansbach, home town buddy of mine was in an artillery unit there in the late '60's and I went to visit on a 3 day pass. Is that f**cked up or what, to spend a 3 day pass in another army barracks We had a great time anyway. Lengrees was my favorite, did radio repair school there one Summer. Delightful.
Oh yeah, I'd wonder about the flex too. The devil's always in the details.

Off topic, but, this is the air cleaner I rigged for my Bendix on a Panny. Typical AM backing plate with the unneeded holes welded shut and ground flat, K&N lifetime filter, and an OEM stainless cover. A J slot cover could also be made to work. This fits in close for good leg clearance too....

Exact same set-up I have assembled for my use!
And it does provide more leg room over what the Linkert and filter had.

Herr Dr.
Quite a bit has changed in and about the Ansbach area..........mostly shut down, and being renovated to other uses.
Wife retired from Bank of America, which was located on Katterbach Kaserne.....where the airfield is located...
That's what I like about you, George, we seem to think and buils about the same, except, of course, for the things you are wrong about, LOL...
But I have not been fond of the internal (infernal) throttle setup ever since I got rid of that stuff from my original purchase 1950 Panhead back in 1967.
I mentioned in another posting that H-D used a pull to open internal throttle on the AMF Shovelheads &Sporties equipped with Bendix carbs through 1973, so that may be a parts source for you....
George....
You could move the fitting inward on the carb's throttle quadrant, shortening the arc length, thusly not needing as much travel with the push wire to achieve full throttle openimg. Eh?
Just drill a new hole, it would not be a perminant modification, and you could go back to the original position at any time.

In/re inner wire, a music store or piano maker could help you here. The wire I use is .055" in diameter, and I bought it online. It's piano wire.....tempered and hardened, never kinks or bunches up. When using with springer bar throttle and spark advance, I recommend bending the end that goes into the slider before cutting to length. The stuff is that stiff that you have to leave a little extra to grab and make the bend.
We had a great time anyway. Lengrees was my favorite, did radio repair school there one Summer. Delightful.
