Honda CBR 600 F4. Displayed near stalling recently when moving off from a stop. At first, I thought I wasn´t feathering it well enough, but soon came to the conclusion it wasn´t me. Since it stalled once and wouldn´t start. Had power, but nothing when hitting the starter, not a peep. After about 5 minutes, it started for no reason then ran properly for several days. Now, it won´t start again. Still has power, not the battery, but won´t make a sound. Welcome any suggestions please!!!
