Dashboard

[Viensal]

Hi,

 

I am a new and proud owner of a 81 GS 750E, and I have a question regarding the dashboard; 

1-Speedometer needdle is bouncing, is it common, any fix ? 

2-Tachy is also quite vague, idle steady and seem to be fine, but anything over 3000 rpm seems to be vague and floating, again, is it common, any fix ?

 

Thanks !

Usually dry or kinked cables. The most common 'fix' is to remove them and squirt some oil down one end while you spin them from the other.

Hi and welcome to OSS. 

 

My first guess would also be the cables. 

Original or slinky glide replacements are rhe next step if lube does not improve the behaviour

Speedo as above but also sometimes the small tags on the front wheel Speedo drive/wheel get worn or bent with heavy handed wheel fitting.

Thanks for the welcomes,

 

I just realized that the RPM is also by cable so I lube up both, we will see the results next ride.  Other than that It is really fun to ride, I was expecting a noodle chassis but it is quite stiff for an old one.

Don’t over lubricate the cable! Too much, and it’ll work it’s way up the cable and into the head. New instrument then required!

Remove cable inner, clean, then re-lube using grease not oil. Leave the top 10cm grease free or it will work its way up into the clock and bugger it up, as ST says above (Motorcycle Mechanics Fortnightly, 1980 or thereabouts....).
