2013 1900mil Hi, 1. I'm just wondering about check hose from air filter. In the manual I can see that if the check hose is dirt is or water visible, I have to remove, clean it and install again. The problem is that in my check hose there is something like gold-yellow oil and there isn't nothing about the kind of "oil" in the manual. Do I have some leaking from somewhere? I can send you a pic if you want 2. After adjusting the clutch lever free play about 10-15mm, how can I find the zone where the clutch is pressed enough? Because all pressure range until clutch touches the handle it's not good, isn't ? Will it be the moment, a little further than friction zone, when the bike starts to go? Or the moment when I can hear the typical sound "CLICK" during pressing the clutch, more or less in the middle of pressing ? Btw. Is this sound "click" a good thing? 3. Do you have the same problem guys like me? When I start up the bike, in first few minutes my engine is going like "wave"- up and down.Check out the video. https://youtu.be/xNBkIlsWUvY When I'll pull the handle just a little bit and come back quite fast to normal position, there is the situation like choke, just for a half second the engine is like "stop running" than come back to normal work. I'll make a video if you want. I suspect, for someone this questions are so simple, I'm just newbie that's why I'm asking , after trying to find something in manual or google Cheers guys
