OK I have a hard time starting my 600 . She has a kacr instead of a compression release lever. She is very hard to start you have to find Tdc and kick her from there. I can kick her all day long and if you don't follow a certain procedure she wont start. The kacr makes it feel like your kicking a marshmello very easy. I just can't fire her up. I just bought her and she runs . drove it and so on when I bought it 2 months ago. But now no matter how I kick her nothing. Spark IS there getting gas has great compression and everything seems and looks fine. She is only a kick start . I wish she had that magic button (starter). Any ideas and input would be greatly appreciated. From my research that I have done I found out that these bikes are hard to start in the cold weather. But I have heat in my shop and still nothing. HELP PLEASE !!!!!
