QuestionDear Bill, I have a 1964 Benly.When going into a turn,engine speed increases.I suspect throttle cable is routed incorrectly.Could you tell me proper routing.
AnswerHarley, It sounds like your diagnosis is correct. I hope that the bike is all standard parts from the factory, because if the handlebars were changed, the cable may not be long enough.

You should be able to simulate this problem with the bike stationery, just by wiggling the handlebars back and forth, with the engine at idle.
Earlier Benlys had an external throttle cable coming from the throttle housing, then routed into a hole on the right side of the fork, around the steering head and then along the left side of the frame, beneath the fuel tank, inserting into the frame hole and then meeting the carburetor.
If your bike has the type 2 handlebars/controls, then the cable runs inside the handlebar (be sure to lubricate the throttle mechanism at the throttle grip area) and out of the hole in the handlebars, then similar routing, behind the forks to the left, beneath the fuel tank and then into the frame.
There is a throttle cable adjuster in the middle of the cable.

see the one on the right.
The cable ends can come out of the adjuster piece and then hang the throttle cable open or reduce the amount of slack available when you turn the handlebars.
If the cable is original, they can get broken wire strands inside the cable which will cause the cable to hang up and not return the throttle correctly. You may have to fish it all out of the frame and run some light oil down inside the cable to ease any corrosion buildup there, plus check it for binding due to broken strands.
You should have just a little bit of noticeable slack at the throttle, before it pulls the slide up. If it is tight and pulls the throttle open instantly, then it needs some adjusting.
