Hi Today when I was thinking about going riding I started my bike (is strated from first kick ). I let it idle on choke for 10 secounds and then turn of the choke. Then bike idled for 20 secounds and sudenly died so I wanted to start it again and after 2 shots from exhaust (first 2 kiks) and after few more kiks without any sound I gave up. Could you tell me what could it be? My bike likes killing plugs but never while engine is runing. I allways had to change the spark plug when it won't start. That is my secound problem. My bike kils the spark plugs once or twice a month (I'm riding 12 times a month). oh and I've cleaned the air filter the day before starting and washed the bike two days before starting.
