As Above, i have a combined reg/rec, what are the symptoms if its failing.

Out of nowhere i have a flat spot around 4k , i can ride through it, but it feels like it running out of fuel. I have had the carbs off and they were clean, fuel tap - Pingle - clean and flows as it should, no other work to the bike over the winter except oil and filter change. Scratching my head with this one!!

Any advice appreciated

If reg/rect working as should,you should get around 14.6 v dc across battery at around 3k revs,if you dont have a meter,start in the dark and see if headlamp goes brighter when you rev up as a quick check..

When my factory original reg rec failed in the late 80's I fitted an electrexworld unit which has been on since.
The symptom was a boiled dry battery and battery acid where you don't want it!

I had a similar problem - turned out the points were pitted to hell!

Cleaned them up with a bit of emery cloth and off we go.
