I am having trouble starting my Suzuki Across on cold mornings. Warm days is fine. Yesterday I checked the voltage of the battery at a whopping 16.5 V, so I don't think the battery is a problem. The bike could be a little out of tune, however it runs great when warm. I guess there are alot of little things it could be, but I don't want to do them all. It just had a major service recently. - It could be - Battery Tuning/Balance Thick Oil Dirty Plugs I have tried adjusting the tuning and the bike runs well in the warm. Still trouble starting in the cold though. Any ideas?
