R100RS cut out on me and won't start

Postby Glynd3 » Fri Aug 25, 2017 10:17 am

Good morning
1981 R100RS
I was riding my bike last night and all of a sudden I heard a little clanging noise, a bit like a stone had come up off the road and hit the bike (No front mudguard fitted) then my rev counter started to fluctuate and the engine started running a little rough. I came to the next junction, indicated, but the indicators didn't work. I carried on for a mile or so, but at the next junction, she cut out and then wouldn't restart. Has anyone else experienced anything like this? I would welcome any advice on helping me fix the problem, please.

Just a note, the battery is fully charged and the lights work, when I press the starter I can hear a low electrical clicking sound. Hope that helps.
Thanks
Glynd3

Hi Glyn,

Does the Horn work?

When you say that the bike will not restart, do you mean it cranks over but will not fire up or that you only hear a clicking sound?
If only a clicking sound, is it a single click or a series of clicks like a machine gun?

As a preliminary to any further diagnostic/faulting work, could you disconnect your Battery and clean the Battery terminals and the cable terminals to bright metal.

Then, before re-connecting, LIGHTLY smear the Battery and cable terminals with Vaseline and then reconnect.

Also check at the Engine/Gearbox Main Earth connection from the Battery Negative (earth) terminal that the Main Earth connection is sound.
Be VERY careful if disconnecting this for cleaning as above as, if it utilises the Gearbox Speedo Cable bolt on the gearbox casing, then this is a hollow vented bolt which can shear or be seized in the Gearbox threads.

Next, see if the bike will start.

If not, despite you saying the Battery is fully charged, put the Battery on charge overnight for 12 hours and then try starting again.

We can take it further from there if necessary. :smile:

Hi Glynd3
any feedback? Ced kindly provided advice and I am sure he would like to know if his solution worked for you
