RE: Hard to start
Hi guys. I'm having issues with my 2007 650 starting when it's cold that's decided to play up this past few weeks. When it's hot runs like a charm and you wouldn't believe there was an issue. Start first time every time when hot. It's just the dreaded initial cold start that's bugging right off. Here's what I've done so far. 1) remove and replace carbs to fully clean out, check floats and set all carbs to spec as per workshop manual inc balance and mixture screws. 2) check valve adjustment all good and set to spec. 3) New plugs. 4) new fuel filer. 5) new air filter. The fuel pump runs and stops ready to start. Oil level all good. carbs needle and seat doesn't appear to be leaking when closed. To start, choke in throttle half to 3/4 and hit start button. winds over for approx. 5 maybe 10 sec and starts. Before, I would set choke to first notch hit button and starts straight away. I'm in Australia so no snow or anything, quite the opposite. Any help would be great as I'm at the end of my wits here and ready to burn the thing lol!
