The weather is pretty cold now in kuwait. I've noticed it takes a few starts to get it Running when cold. It never used to do that, but I haven't changed a thing on it & didn't have a problem on the last ride a week ago
I was advised by my mechanic to switch on the ignition till the fuel pump stops whining, switch off then repeat twice & start engine. This does help on mine.
My battery tender came with a flying lead that attaches to battery & socket end is threaded to cockpit by the transmission tunnel.
