The Fi lights when riding on bumpi roads

i have a problem with my vfr since the moment i bought it! when i ride it on bad roads sometimes the moment it "jumps" the Fi lights for 2or 3 seconds and the engine looses power.After that in comes back to normal.
that's one problem. another one it's the low beam. sometimes it's not working. if i turn on the hight beam and then return to low beam it works.

do you have any ideea why is that happening?

 

I had a similar problem, it was a loose groud connection with the battery. Check it out.

My suggestion also, saw a VFR with a similare issue last weekend, ended up being a loose Ground cable.

 

thank you very much! is there a particular place where i should look for the loose ground cable ? ...so i can go directly to the source?

 

Try this link from UK's VFR site it details " FI light " trouble shooting and shows photos of the Earth Block location.

If memory serves there is another earth lead connected to the frame beneath the right side fairing that you could check as well.
