Ok guys, so I built up my 350 about 16 years ago and remember that it was over oiling as the oil pump section of the throttle cable was too short. I keep reading that the only way to go is buy a genuine cable. Back then I was young and poor (now I’m old and poor) so there was no way I would have splashed £100 on a genuine cable, still wouldn’t. I remember altering it but couldn’t just remember how so kept quiet when the subject was posted. Anyway, my project 250 came with a genuine cable but the twistgrip end had a couple of loose strands so thought it best to replace. So, I bought. £12 throttle cable off eBay and it came today. Fitted it and yes, the oil pump section is too short maybe 20 degrees past the mark. First thing I noticed was the adjuster end of the oil pump cable has a circular stop built in to the cable adjuster that sits in the side casing above the oil pump. This stop was bigger than the counter bored hole so was holding it back. Cable back off again, and I carefully filed the round stop so it sat snug in the hole and that got me over half way to the point of being ‘in adjustment’ Cable off again and I measured the depths of the thread in the adjuster sleeve nut, then the length of thread on the adjuster screw. 18mm and 9mm respectively. So you’re not able to back the cable off to the limit of the sleeve nut. Cable off again. With a junior hacksaw, I carefully sawed off the end of the sleeve nut in sections, careful not to touch the cable itself.. I took it back by 6mm. The cable could then retract further down the sleeve but and voila! It was out of adjustment, so needed ‘tightening’ up to line up the marks. Hope this all makes sense, but it’s done the trick for me (twice) Adjuster sat snugly in the counter bored hole:  Sleeve nut cut shorter and ‘in adjustment’  You can see here that the cable needs adjusting up after modifications  Hope this makes sense! The last cable is still going strong too after all these years. |

I wonder if anyone has found any pattern ones that fit correctly?

Think also if you had a split die you could bodge up a die holder (vice grips but not squeezing the die shut) you could cut the thread on the elbow deeper too but really just similar to what Bill has done

Good work.
This has bothered me for literally decades. But not enough to actually do anything about it obviously.
Thanks for taking the time to share the solution.

If i was to do another, it would only take ten minutes now with a file and a junior hacksaw.

I'd be tempted to go at it with a angle grinder.
But I'd probably then be buying another cable....

I have some aftermarket cables, sent one off to somebody to test on here to see if they where a good fit etc, can't remember who it was now, or whether or not they ever let me know if they where a good fit !
Oh well, something else for me to sort out when time allows, think I have 30 of these cables as well!

It wasn't a good fit but I can't remember why so we both have memory problems lol. |

I have ordered one of the cables billbott used and got a different Japanese made one to also try.
Might be worth listing make/models of different cables and if the oil pump cable is correct or not. The Japanese one appears to have a smaller OD ring around the entry to the engine casing and fits in the recess perfectly.
I have just made a measurement using this cable to see what the maximum amount of cable for the oil pump is sticking out the end.
Measurement from the back of the stop to the start of the nipple is 152mm with the adjuster wound fully in.
Can someone do the same measurement on an OEM cable?

Hi Rob, just measured my never been used OEM one and it’s 156mm from under the shoulder to end of the nipple as in your pic.
Mark.

Rob,
Just measured a used OEM cable at 156mm same as Mark above

I got the same cable as billbott used and it is branded as a Hi Level 478545
This is considerably different to the other one I have.
The better one I have is a KSI one made in Japan.
Will do some measurements when I get chance.
Anyone got any other branded new pattern ones?

The oil pump end is a different length. Not fully measured up but visibly different.

Jon I've got one of Norbo's Jap made pattern cables, fitted perfectly, been on about 4 years now with no issues, I have got a gen Yam one that I got from Malaysia a couple of years ago for a very good price for a spare |

Really ? you guys have no qualms re dicking about with altered crank throws and rod lengths.
But Simple Stoopid Throttle cables are a problem ??
Go to a decent bicycle shop and Find and Buy hi quality Bike cablings
Bicycle weenies are V fastidious rascals indeed about parts quality.
Consequently Bicycle parts often put Moto bits to shame.
Buy a few lengths of your choice of cables inners and outers, there is a mix 'n match choice usually.
Fairly reasonably priced.. Truth be told.
Then Cut & Solder for a bespoke fitment.
Fairly easy /straightforward and you will be amazed at how 'slippery' the pesky cables can be.
Often falling out of their sheaves during assembly attempts.
Even Yama San's finest cables are in no danger of doing that .

I tried the potentially good cable today. Oil pump end was fine but the carb end did not fit in the elbows!
So...mix and match time. I used the better oil cable on the cheaper cable and it all fits and works!

I can probably make some adjusted ones up if anyone needs one.

Each to their own but I won't be using a cheap cable
Remember back in the day my lc2 used to have an occasional sticking problem
Not fun when yhrashing up to a roundabout thinking you were a late braking god, shut the throttle and it kept pulling
I wasn't covering the clutch lever, it was the kill switch 🤣
If they are Teflon lined and the splitter is good quality they should be fine
