Hi , How much longer do the inner cables need to be . Not much the slides are just about down but I would need some slack so I can adjust to at the moment I haven't got the lock nut on either , ??

Hi, maybe a bit extreme but have you thought of getting a throttle cable made? I'm sure 'Venhill' could do it.
Just a thought.

Bit of a git as I just brought the new genuine one but if needs must !! I might cut a bit of the end of the cable's where they go into the junction box 5 mm would be plenty and give me what I need ! Dunno will see tommrow hey π

Mmm, not had this issue yet as I haven't fitted my throttle cable, but I do know I had to mod the cable ends (ferrules) on the Cafe racer bike to work properly with the Pwk's on that bike. The Keihins are a generic carb, so some fettling is likely when fitting, although I had no cable length issues once I sorted them. And they use a swan neck fitting on the carb tops. That bike uses a Pv throttle cable, so I wonder if the carb cables from the splitter box are longer on a Pv ? Not sure what I've got down the shed, but if I can find an old cable I will measure the short cables from the splitter to the carbs - I'm not expecting them to be hugely different, but even a couple of mm may make a big difference to the slide positions. If you had to get new cables, maybe just the 2 from the splitter, rather than a complete bespoke cable ? Dusty

Dusty Morning dusty , yep my cable was way short the slides are still not seated ,steely has kindly offered to possibly make me X2 carb cables up with longer Inners ! This morning I'm going to measure up see how much more I need ,be nice to get the lock nut on too so I can set the slides synchronization etc ,I will let you know the length dusty ,thanks π

If you are using a genuine 4LO cable you will have to extend the length of free cable which goes into the carb. On my bike (4LO) the 1 into 3 cable slider became very critical. The slider has just enough movement to lift the carbs to the full throttle position. This needs to be checked from the front of the carbs. I bet there are a few people riding around out there with carbs that are not giving full potential.
If you don't want to chop your cables i'm sure some one like mutts or Venhill can send the correct size out going cables for your carbs.
Oops looks like I'm a bit slow at typing.
Thumbs up for Steely
One other note make sure your adjuster is not too deep on the inside of the carb as this could act as a stop for your carb slide.

Hi ,thanks for the comment π,it's a genuine air-cooled cable , maybe the same as LC ? Yes I need longer Inners on the X2 carb cables I haven't got enough to get the slides to seat ,it's bloddy close but everything is so tight thers no free play at all ,but steely might be able to sort me out ππ

Hi Sidney just looking through your thread again. Is it not possible to make some fittings up in the lathe to accommodate your air cooled cable that fit in the carb tops? I see that the oil feeds are blanked with a screw, air tends to leak past the threads. I guess it's temporary? It might be better to put a dab of sealant on the threads or a ball bearing to seal the pipe off.

Hi yes the oil feed is blanked off just temporary at the moment as I haven't got the oil tank on ,it's just to run it up ! But good point π I don't know what I could do tbh at the moment longer Inners are what I need then I could look at something that that π

Would shorter outers make the overall cable too short?
Iβve shortened outers before by part sawing through then work hardening the last bit to snap it off.
I know itβs not ideal, but a quick reliable fix.
If it were me, I made longer carb to splitter cables as my bars are higher and the overall cable too short.

No the problem is the carb to splitter cables , either make the outer shorter or new ones made with longer Inners ,which I think we're going to do π

I know you can buy nipples, but as you have a lathe you could make your own like I did from brass.
Countersunk end, splay wire out then solder and file.
Done it loads of times on different vehicles.
That reminds me though, I need to order some more stock so I can make one at the time when next needed without having to wait.

Yes its nice to be able to do as much as you can yourself . Me i still need more practice at ali welding with my tig . I wait till i have a few or five jobs before i fire mine up . Hmmmm .

I found an old Lc cable in the shed today, and measured the 2 carb cables from a given point on the splitter box to the nipples that would raise the slides, and compared it to the genuine aircooled cable I have. The aircooled cables are actually 12mm longer than the Lc's, so Lc cables aren't gonna help. I did message Chris today after checking some pics I had of the Cafe bike. I used some second hand Pwk's with a modded cable, taken from another bike previously. When I took it all apart, the cable had been made to work by removing the silver ferrule at the very end of the cables from the splitter to the carbs, and some of the outer casing had been cut back. This allowed the cable outer to fit into the Pwk brass adjusters on the carb tops, as they were slimmer without the ferrules, and also meant the inner cable was longer in relation to the now shorter outer sheath, thus allowing the inner cables more range of movement. I then did the same mod to a new cable that I fitted to the Cafe bike - this was necessary as the donor cable had been cut so didn't have an oil pump cable from the splitter box. Dusty

Hi Chris, what about removing the gaskets from the tops and using Yamabond to seal them, a bit of a hash up but it should get you 0.5mm or so? Andy.
