Yamaha YDS

[Ant1969]

I have a wire hanging from  the engine (YDS5) which I believe is for the neutral light (Light blue)  and have no idea where it should go as I have looked over and under the engine, here are some photos. Also can anybody help me out on a  tachometer cable as one did not come with the bike like any measurements: 

1. Outer cable tip to tip length and outer cable fittings required – usually female threaded spinning fittings on the outers.
2. Inner cable tip to tip length, and the square section size at both ends of the inner (May be same both ends)

Thanks

Hi,  the blue wire should go to a plate, beside sprocket, looke here ,https://www.cmsnl.com/yamaha-yds5-1967-usa_model8304/partslist/E-11.html#.XwdyzShKjb0

Hi 

Thanks for the reply but still can not see where the wire goes See photos

Its a weird shifter on these things as i recall, there is no shifter drum with the usual detents. The gear leaver turns a ring and that affects the shift forks on a long pair of cross shafts. Made sense to someone?  Looking under the bike my bet would be something on the round raised area in what looks like a sump but isn't.

That's the shift ring and the neutral detent will like as not be around there, wire looks about the right size. I'm scratching my head back to a yds i messed with with my dad when i was 15.

Hope it helps.

Thanks that was a great help I did take the bolt out which was filled up with red hematite but my next question how does it fit in the bolt or do I have something missing. See Photos

I think that is either dead or something someone had that filled the hole.

This is what it should look like, https://www.cmsnl.com/yamaha-yds5-1967-usa_model8304/neutral-switch-asy_1568254000/#.Xwrj_OWSnIU

Thanks for that it seems that the person who had it last got rid of it the reason could be cannot get the part anymore or changed the gears so it was not needed but not sure and l did try that link which was very useful but it is out of stock. 

Thanks again much appreciated

This is the part number, 156-82540-00

It was used on a lot of yams of the period, 1964 yds3, 1965 yds3,  yds3c, ym1, 1966 yds3, yds3c, ym1s, 1967 yds5e, 1969 ds6c, 1970 ds6b, could well be more.

Looks like you might need to get one from the states looking at ebay, fowlers might be able to do something. They do seem to be able to pull stuff out of the bag, sometimes just speaking to one of their guys on the phone can get you what you need. Has worked for me in the past.

Thanks very much for that just the neutral switch off E-Bay from the states now all a need is a tachometer cable couple of carbs
