Looking for electrical gremlins on my 08 1125r I found loose ground cables, one OEM the other running to starter. Ground bolt at bottom of frame / fuel tank is 6mm. I could not get tight enough so as not to be able to move slightly by hand.
So, I reversed cable (fat battery) terminal with skinny ground end and enlarged hole, large enough to go around subframe bolt.
Starter has more oomph and idle quality has improved.
