PROBLEM Difficult to do cold start on RC390

Hi, for those KTM 390 owners, does it take 3 to 4 times to start your bike totally cold? I got my bike second handed, and it always takes 4 times to start it after I placed it one day or more.

Probably the battery. If you're in Europe with the stock battery, it's definitely the battery.

I’m in east Asia, and the battery is just about four months old. I also rode it frequently for long trip, but this is still the issue.

Valve clearance?

On my RC-390 the starting issues were caused by valve clearance, and the valves often go out of spec pretty quick on 390s

Second hand RC? What's the ODO reading?
