1975 DT250B Clutch cable woes..!! was created by Andy L

First of all HNY to all members and moderators.
I am looking for a new clutch cable for my '75 DT250B. Simple swap you would think, but after buying (and then returning) no fewer than 3 already I'm stuck..!! They always come up too short. At worst 120mm or at best only 40mm short, either way they have all been too short. Outer cable adjustment isn't the answer because it only gives a variation of roughly 25mm max. Nether is the routing of the cables I've tried as I have a detailed service manual showing exact cable route. My old clutch cable is totally knackered such that I can't even use the various 'components' on it to make my own cable from scratch. Yamaha changed the position of the clutch rod actuator arm from the top of the engine to the bottom for the 1975 B models. The critical measurement seems to be the inner wire length which is 1260mm nipple to nipple on my old cable. Even accepting this has stretched over the years I still need an inner wire length of minimum 1235mm. Can anyone point me in the right direction for a supplier please? I know one option would be to buy a whole short cable and use it's components to 'build up' a new cable using a kit, but surely before going down this path there must be a supplier somewhere? I'm located in the U.K. but if necessary I'd consider taking a hit on the cost of P&P + import tax from the U.S.A. Any help would be greatly appreciated, thanks AndyL.

Just to add my 3 cents worth of experience on measuring old cables. The sheath will compress more that than the cable stretches making it confusing to measure. I've read that there have been some aftermarket cables made by measuring used cables for dimensions resulting in incorrect lengths.

I have only '71-'73 Enduros. I've measured some really used ones and found that the cable was almost the same length as NOS but the sheath was much shorter.
The hours spent riding my Enduros is not deducted from my life span.

Yes, I had issues with the new clutch cable that came with my RT2 as well. In this instance, the outer cover was so short in relation to the inner cable that it wouldn't even reach the crankcase cover! :EEEK I ended up buying a nos period repro and that fitted fine.

Early models have the worm gear actuator in the side cover.

1974-1976 250/360/400 have the actuator underneath the engine.

1977 on (monoshock aka "MX" in some countries other than the US) had the lever on top.

Rather than scrounging for a used or poorly made reproduction you might try buying the cable new from Yamaha?
