FI light comes on with headlights/brake-stalls

Noticed it flickering yesterday before I pulled away but it went out so thought nothing. This morning I start and ride down the road and put my headlights on and the bike stalls.

FI is constant no flashing. Bike has power but it seems voltage drops and kills the engine. Using either brake the light comes on dim. Brake and headlight result in engine stall. 

Fi LIGHT turns off during pre-ignition and bike is fine without headlight. 

I installed a new RR after I heard a bee like buzz from the front. What should I start checking. I have a volt meter and grounds seemed fine a few months ago. Could it be a relay? How can I check those? 

Thanks for any help. This forum is invaluable for those of us with older bikes.

It's the earth block.

All the earths go to a joining rectangular plug near the RR taped into the main harness.

This needs to be removed and all the earths soldered together with a new earth wire back to the battery.

This will fix your problem.

I think I found two of these last time. I'll have a look and hope things correct!

I had this problem and looked for all the post but could not find them. My bikes problem started with the FI light flickering and with in 6 months the engine was cutting out. FRVOZ is correct remove the orange plastic ground block on the left side of the bike, remove the covering and solder the grounds together including a larger dedicated wire to the frame ground  which is on the right side of the bike. I also installed dedicated grounds to the frame from the battery, the RR and two grounds from the ECU. I believe Frankenviffer was one of the first to post up on this.

Anyone who owns one of these bikes would be smart to do this mod.

With the ignition on not running this felt warm to touch. So every wire should be together? Could I use electric wire from a household appliance to ground? Time to practise my soldering skills tonight!

^ That's the post thanks Auspanglish!

Use a wire made out of the same metal that is slightly larger than the wires going to the ground block

Will the VFRness help with this issue? I'm not currently experiencing issues just curious.

VFRness just helps alleviate some issues relating to the stock harness and stock rectifier; it doesn't affect the earthing block directly.
