Does anyone know what the length of clutch cable should be on SD250NA? Wemoto offer two options, one (I think would be standard) is 102cm inner and 90 cm outer. The alternative offered is 126cm inner and 115.5 cm outer. The cable I currently have measures about 118 cm inner and 105 cm outer  and is on the maximum adjustment out at both clutch end and lever end. My understanding is that the only difference to adjustment would be the difference in length between inner and outers on the cable. There does not seem to be much between them all based on that. I also need to check if the clutch plates are worn as that could be effecting the adjustment I guess? Any thoughts on this welcome! Thanks. |

I had a bit of trouble years back trying to find one the right size for my 250NB & got a cable kit from Venhill & made my own. A few years later I replaced it, can't remember where I got it from, but I've a note filed away saying inner cable length 102cm & outer length 90cm. The note's dated 1/2/2018, so I don't remember where I got it from, but it could've been Wemoto, those Slinky Glides are usually ok

Thanks for that Ian. I need a new cable anyway, but I'm not sure if being a bit shorter than the current one will mean I can get more adjustment on the clutch. I am probably going to have to look at those plates...a nice winter job! The bite on the clutch lever is right at the first few millimeters.

I have put a thread on this forum before about this problem. Just after getting the 400 the clutch cable broke at the engine side the cable I got was nearly fully adjusted but worked. 4 years later it broke again at the same end so I wanted to know why .a friend had a 250 that was very original and low mileage and found looking at the clutch arm from the side of the bike the arm was at 5 to 12 and at 12 when pulled mine was at 12 and 5 past 12 when pulled and you can see why they snap .I changed the clutch plates made no difference so got a clutch arm and button of a guy called Los and it resolved the problem and been fine for the last 10 years now and the clutch cable as plenty of adjustment left

Cant comment too much on this as to the SD, But on the Dream I had issues with the clutch cable reaching where I wanted it to go, it turned out to be the height of the handlebars dictated it, as it would. I contacted Silvers and they have over 3 sizes of cables for a Dream/Hawk depending on the year and country it was made for, as mentioned, it depends on the height and length of the handlebars compared to standard. If an SD has different height and length through certain models, this might explain it maybe. You bought a set of bars from me did you not? Chances are wemoto have maybe sent the wrong cable, even silvers did that to me. I have cables here, if we know the size you need, I will send you one down. Gee. |

Yes I had Dream bars on my bike and swapped them with you last year for the SD bars. So I guess that the cable that was on mine was longer to suit the Dream bars. What I need now are the standard SD which I believe are 102cm inner and 90cm outer. If you have one of those spare that would be great. Thanks! |

I got the slinky 102/90 from Wemoto, quality is good, fits and works the clutch ok but both adjusters are wound right close to the limit.
So if 102/90 gives 12cm of play and 126/115.5 gives 9.5cm, that makes me think the 9.5cm would be bang on, would bring the adjusters in to a decent position.
Caveat, I don't know the condition of my clutch plates wear wise but I think that couple of cm difference on the longer cable would make it a good fit on my bike. I'll now probably try the longer one at a later date.

So in theory the longer cable will be a bit shorter play on inner and have more adjustment. However the longer cable can be a bit long and wander a bit too close to the downpipe unless you tie it in, which is not ideal for a clutch cable. I wonder if you and I have worn clutch plates and that is the real issue of lack of adjustment. I wouldn't be surprised on my bike as I think a previous owner was a bit heavy handed based on state of it when I took it on! |

Got the Slinky 90 / 102 ones from Wemoto and fitted today. A bit more adjustment now and may be ok. But probably will take a look at clutch plates at some point, as still not much adjustment.

its an odd one this, my own 400 'thing' has the clutch cable (450 nighthawk I think, used whatever I had chucking about) set with both adjuster nuts at the same side at the lower end, that coupled with the adjuster at the bars just gives me enough to get the free play required at the lever to protect the clutch bearing.
I went as far as to order new clutch plates (off ebay, my advice on those is dont bother, the set I got were one plate short and they deliberately warped the plates to fill the basket, yes you did read that right) so I did what I should have done first and measured the friction plates, they were fine.
I wonder if part of the difference in cable length is down to the later type clutch baskets? they were definitely fitted to the cb450sc/cb450dx models and maybe later model SD's?

and is on the maximum adjustment out at both clutch end and lever end.
