Recently bought a 2013 EFI YBR125 and it seems to have a fault, but no error lights (The light does work on first turning of the key, so not a bulb issue). The bike starts first or second stab of the starter button and ticks over lovely and quiet, BUT is is really fluffy at picking up when cold and nearly stalls, so to be clear it doesn't increase revs cleanly, it has massive lag. Once it's ticked over for a few minutes it goes away and runs fine, and picks up cleanly. Air filter is spotless, plug looks OK if a little rich, has fuel. Is this "Normal" for cheap injected bikes, was expecting a nice clean pick up and pull away from the off??
Any advice/views greatly appreciated, as i have some long runs planned. Cheers Ian
