Ok, lately I've been riding on some rather bumpy roads, and I've notice a few times as I go over a bump I lose power for a split second and my F1 light comes on. It probably only lasts a fraction of a second, but I want to know whats causing it. Loose connection somewhere? (I checked the battery cables, they're tight) Anybody have ideas where to look?

 

Check all the harness connections. The FI (not F1) light is probably coming on cause the gauge cluster "resets" when the power comes back on.

 

i'd imagine if you hit a bump big enough that your bikes top over sensor could think you've dumped it

i think it'd have to be some serious stuff you're riding over to get to that point though

 

This happened before with me - was the cable on the battery. Check both terminals.
