69 Lightning A65L:

Replaced stock AMAL 930 Concentric Carbs with Premier versions & installed new cables. Everything else on bike is stock.

With the threaded cable adjusters on carb tops all the way in and carb idle screws all the way out, It looks like the inner cables are at-least 1/8” too short to allow the slide to bottom-out. (I have a 3500 rpm “idle”.)

I double-checked the cable part nos to make sure they are correct – Part no 60-0813. Outer length 38” x inner length 42” Purchased from Draganfly It's an Emgo Taiwan part.

Does this commonly happen? Should I try to stretch the inner cable or shorten the outer cable some way or what?

Thanks in advance,
Paul Stuverud

I have shortened outer cable with a Dremel tool when I experienced this problem.

When I had Mikunis on my A65 I always had to make my own cables.
Unless someone happens to make cables specifically for your carbs, get used to it. Soldering is a good skill to have.

Sounds like your using cables to fit in ferrule tops going into a carb top which has the adjusters? you'll soon know if the cables also have mid-way adjusters in them.

If they are the type with mid-way adjusters, they are better! you'll be better off long term swapping the carb tops than to swap/modify the cables

Cables are frequently problematic, especially throttle cables. Triumph unit twins with Concentric carburetors used "top-hat" shaped ferrules on the end of the throttle cable to be fit directly into a drilled hole on the carburetor top cap, and were adjusted by way of an inline threaded adjuster. Cables designated specifically for BSA unit twins have a plain ferrule on the end and the threaded adjusters on the carburetor top caps are retained for cable lash adjustment. Often times, especially when non-stock handlebars are fitted, a universal throttle cable is called for to solve the fitment problems. We offer a 53" universal throttle cable from Barnett which includes fittings for custom applications, or when an original cable is not available. Soldered universal brake and clutch cables are subject to high loads and are more difficult to solder up to handle the load reliably, but throttle and choke cables, which are subject to lighter loads are relatively easy to make.

i generally make my own as its impossible really for me ever to get the correct ones as i prefer european bars which are lower and shorter. barnett used to make a cable terminal and ferrule assortment for british and us bikes, they also sold brake,clutch and throttle cable in bulk lengths. i still have a bunch i got from domie racer ages ago. i use a solder cup and a electric iron with 50/50 solder. never had a quality related failure.most of the time ferrules and terminals can be reused

These folks have everything you need to build cables.
