Hi. i need someone with some knowledge to help me figure out why it's so hard to start my 640 Adventure. i have charged the battery, pulled the decompressor lever and the engine struggles to turn. I also try to kickstart it but i really can't crank it easily (noob). I have tried for 10/15 minutes ever day, an sometimes, all of a sudden, she starts. this is day in, day out. The previous owner had an extensive service done. bike has 24,000Kms. i am really getting quite shitty about this. when she goes she's fine, but with this issue, i am so frustrated. Can anyone in Brisbane help me figure it out? I am in New Farm. Thanks, Daniele ps: i am happy to pay you in Beer.
