Throttle cable routing
« on: September 16, 2024, 05:09:48 PM »
Can someone clarify if this is correct, it seems the only way I can get it to fit nicely.

Out of throttle, around the front of the right hand fork, under clock bracket, around headstock and on the inside of left hand fork. Down the left side of the frame tube and under to the carb linkage on the right.

I can only comment on my 500K0 when it had it's original US bars but that seems about correct. The cables change from the left side to the right above the ignition coils

Should they go through the hole in the frame where the coils mount?

At the moment I have them going under the frame, below the coils?

On my 500 the throttle cables loop from the handle bars through the right side of the gap between the headlamps to the right side under the clocks straight along the right side of the frame passing on the outside of the right coil to the throttle bracket. Might not be original but a nice smooth run. I have UK bars on my 500.

Think I’m going to leave mine as they are. They seem the best fit.
Just looked at 2 Honda manuals and still unsure what the correct route is, the lower image seems the best fit.

My 500 is like the first photo, interesting printing error on the second photo where the clutch cable is called the choke cable!

If your cable action is smooth and moving the steering does not cause the revs to change then what does it matter.

Cables are smooth so they are staying as they are.

This method is in Tricks & Tips to help anyone who wants help with image size.
I download my phone photos onto my laptop, upload them to Flikr then paste using the URL link process.
It could probably be all done on a phone but thats beyond my skill set.

It took me a while to grasp the process when I was first shown it on the Nissan 4x4 owners club site.
Now I don't even have to think about it it's become automatic at the young age if 76!

Who says OAPs aren't tech savvy.
