Notchy accelerator

My SE with twin SUs suffers from a slight tightness / stiffness on the gas pedal when moving off from a standstill. It is fine once on the move. I did attempt to get some oil down the cable by removing it at the carb end, but without a dedicated cable oiling device little improvement was made.
Does anyone have one of those cable oiling devices? I did have one years ago but it obviously went AWOL when we moved in 2017.

I doubt oiling will be a long (or even medium)term solution. I suffered, bought a new cable and not a lot better.
Solved using a bike brake cable that had a teflon liner and a supe smooth inner, used the original adjuster thingy and a solderless nipple. All super smooth now and very light.
Parts bought off eBay. Took some searching to find the best stuff.

Make one yourself. Buy a good teflon lined outer cable, a decent innercable, some adjusters/ends and you can reuse the bulkheadpiece from your old cable. For a few pounds you have the best cable and the first take off will be like a rocket...

Yes but i noticed some are teflon lined and some not. They all look the same but as you can see in the pics one has a translucent fitting part and the other a solid blue. One has an crimped end and one an "open" end. Look what you buy but best is to ask the seller to phisically check his cables as some have generic pics in the advert and you receive something slightly different. These blue cables are not all the same.

You shouldn't need to do any of this, if the cable doesn't work, send it back till you get a working one. It is a simple component and it shouldn't cause any problems. The one I bought from robsport works perfectly.

I don't think the cable itself is the only possible problem here! It's also worth checking the "cam and roller" bit of the linkage under the carbs for smoothness and freedom of operation. Also something as silly as incorrect quadrant adjustment of cable and linkage can give very stiff operation from having the cable pulling in an incorrect manner. Hard to explain in words, will have to do a drawing and scan it!

It's also worth checking that the top of the pedal rod is correctly aligned with the hole in the bulkead. Time and old age can mean a misalignment here that will have the cable pulled at an angle, which wears out the cable prematurely, as well as making it stiffer in operation!

Whenever I top up my carb dampers I also drip a bit of oil onto the throttle spindles in the hope that it will reduce any wear in the bearings and help the spindles to turn freely.

I don't suppose it will hurt, not sure it will make any different, surely if oil can get in between the spindle and the bush it would simply be sucked straight into the carb?
