Geiger Posted April 10, 2021 Share Posted April 10, 2021 Hi everyone, I have owned several Yams over too many decades I now have another one. RT1 B to be precise, like a forerunner of the DT. Problem is locating a tacho cable in the UK. I know there will be one from a different model. it's just finding which one. So here is my request. If anyone can spend a few minutes measuring their tacho cable and then let me know the length and their bike model I can probably get a cable to do the job. The length I am looking for is 865mm, or within a few centimetres, with 11mm and 15mm screw cap fittings respectively. Any help would be really appreciated.

mike1949 Posted April 10, 2021 Share Posted April 10, 2021 Mmmm Geiger, First of all welcome to the forum but I think your best bet is to go into this forum and this particular section and introduce yourself first, then go into the relevant section and then relay your problem/question. The reason I suggest this is that we get a lot of "one hit wonders" on here that get their answer and never hear from them again. Mike. Link to comment Share on other sites More sharing options...
Geiger Posted April 10, 2021 Author Share Posted April 10, 2021 Yes, I can imagine. I was a member a few years ago, but when the Yam went I didn't bother to renew. Link to comment Share on other sites More sharing options...

NE0 Posted April 11, 2021 Share Posted April 11, 2021 (edited) hi Geiger, DT175MX is 77cm, however, a useful site is Wemoto. just put in "yamaha Tacho cable" in the search field and a lot of the cables have lengths published. i.e: Tacho Cable Yamaha DT 250MX 1977-1982 Outer 800 mm Inner 825 mm Inner thread diameter 11mm Outer thread diameter 16mm if you leave out "Yamaha" then it lists some 120 cables for different makes. Presumably the part number is B38-2240 as I see there is one on ebay in USA at present. Edited April 11, 2021 by NE0 Link to comment Share on other sites More sharing options...
Geiger Posted April 11, 2021 Author Share Posted April 11, 2021 Thanks for this Neo. I found the cable in USA at KDI Reproductions for about £12, but with £50 postage!!! 1 Link to comment Share on other sites More sharing options...

blackhat250 Posted April 11, 2021 Share Posted April 11, 2021 Welcome",, the MX models have longer forks,, twinshock are shorter ,,the later DT models,= bottom fittings are held in with a circlip not screwed tho , Link to comment Share on other sites More sharing options...
Geiger Posted April 14, 2021 Author Share Posted April 14, 2021 With the kind assistance from Neo I did contact Wemoto and found a suitable tacho cable which is only 25mm shorter than standard, so I am pretty sure it will fit ok. I will post when fitted. Only down side is that it is black and not gray, but you can't have everything on a bike from the 70s. 1 Link to comment Share on other sites More sharing options...
Geiger Posted April 15, 2021 Author Share Posted April 15, 2021 OK, just a quick update. I did indeed get a cable from Wemoto, and it is now fitted!!! I chose the Yamaha RD multi fit as it has a gently curved fitment at the instrument end. Part no.AC 4245. The other option was for a DT 125 RD 350. Part no. AC 3665. This one has a straight fitting but does have a heat shield spring. I happened to have some springs from a XS 650 restoration I did a few years back, and fitted one to the cable i bought. Many thanks to everyone who helped. 1 Link to comment Share on other sites More sharing options...
