Of course this begs the question... what are the next throttle cables to dry up?!
Norbo still has some Jap made (same factory as the OEMs etc etc) for other bikes... I know he's rarely a salesman, but I think we see where this is going lol

Ok I thought I’d try one from Yambits. It was around 15mm out on the oil pump feed. I’ve written to them and sent it back. This was their response. Hi Vic, I have just been going through our stock of cables and have found some that appear too short. On further examination it appears that the cables are twisted in the junction box. This means the overall lengths are incorrect. Whilst it is slightly fiddly to swop the cables over it does seem to explain why some cables appear short. We are still happy to refund you if that is how want to proceed. If you could mention on the forum about the twisted cables and that if anybody wants to return a cable they believe is faulty to just get in touch with us direct that would be great.

Vic, I am fairly sure the cable Shaun got from me fits correctly, the quickest way to confirm this is for Shaun to measure the free length of the oil pump part of the cable, I'd do it, but not got one in stock at the moment, I'll be ordering some in due course, if the one Shaun has is correct I can order a load of them
Shaun, any chance you could do that, plus it means if its wrong you can pop it back and I'll modify it so its correct

I think I have an original one kicking about too and will compare to that and report back.

Thanks Dave I will definitely have a couple off you if you can get them.
I’m just gob snacked that the amount of cables that are available from multiple sources are all the incorrect length.
I sent pictures of the cable to Yambits. It was 7mm out on the throttle side and 8mm on the oil pump side. When fitted the carb side was ok but the oil pump would hit the stop on full throttle and that was at the lowest cable adjustment.

I've just checked the one from Mutts against what i think is a genuine one. Can anyone confirm its gen from the pics? The new one looks ok, but dimensionally is about 12-14mm short on the oil pump cable. Even taking cable stretch into account this is probably too much to adjust out. See pictures... I will still try it out on my current build but i'm at least a month or 2 away from that point.

Looks like a universal issue.
Dave/Norbo Can you see what you can do about making pattern cables? There is a market for them....👏👍

I'm hoping it will fit if I trim a bit off the oil pump outer sleeve.

Shaun, just bob it back, bring an original cable with you and I'll adjust it properly and make it all good so you never know its been done, I have the correct ferrules, ferrule crimps etc, will only take me as long as it takes you to boil the kettle and make us both a cuppa !! - or bring them both to Newark and I'll take them back with me and sort for you Vic, I'll take some measurements and order another cable, then adjust it to the same as Shauns once I've done it if you want

Faced the Crap cable issue long ago. I solved My problems by going to a Bicycle shop and Buying the cables / bits. All of which were Surprisingly cheap and of MUCH higher quality that the crap we get offered. Only issue is one needs to learn how to decently solder SSteel braid cable. \A bit of a learning curve but not too steep.

One of the best things I bought was a "solder bath" which does the soldering as per factory and the correct "flux" for S/S cable, I buy all my parts from Venhill as they are the best ones I've found, tried a good number of other stuff, but they seem to do all the right size nipples, ferrules, teflon lined sleeves etc, I also have the correct ferrule crimp, so makes the cables look factory, as you say, well worth the effort in my case

Hi Dave Just looked at a video on YT of a solder bath. The guy heats up the solder then inserts a cable and it gets soaked in solder...then what? Do you then use a soldering iron to add the nipple? Kinda confused here, par for the course Alex

Kinda confused here, par for the course Alex no, you put the nipple onto the czble first, then you use a "bird cage" tool to prepare the cable, slip the nipple onto the prepped end, then dip it in flux, then into the solder bath, job done

Ahh. Sounds brilliant. I'm going to give that a go! Thanks Dave, always so helpful, it is appreciated.

For those who only make a few, I did it like this:
Nipple on, slid out of the way.
Lightly clamp the inner cable with a few mm showing.
Using a centre punch expand the individual strands at the end of the cable.
Slide nipple back into expanded bits - they should fill the countersink bit on the nipple.
Flux & Solder - I used my hot air gun, rather than a soldering iron, as mine is a weedy electronics one.
The main job of the solder is to hold the cable splayed out so it can't pull through the hole in the nipple - you're not trying to "weld" the 2 parts together.

could someone check the actual length of a gen cable from the nipple on oil pump end back to the fitting that seats into the side casing when it is pulled tight and straight ? ill check the length of my (still ok) old original one that i have and if it IS a gen one , there's a cable manufacturer in my home town who will make a test one for me and if its spoyon he will work out a price for maybe 50 at a time ? cheers guys PM me piccies of it being measured if you would and ill show everything to my guy

I've got a Shambits pattern LC cable here. Of course, the oil cable is too short.
I'm wanting to have a go at modifying it to fit, tho.
What is the proper length of exposed oil cable?

Post by peter007 on Feb 5, 2020 17:39:37 GMT 1
Doers anyone know the correct length of the cable to oil pump as mentioned ? The guy local to me has seen mine and is happy to make them at a good rate for us. Just need to know the exact length to have one made . Or is it a closely guarded secret as quite a few guys have asked the same question ? Pete 😀
