I need to do something with my clutch. I am not sure what... either change springs or change clutch but something has to be changed. When I launch my bike, I am getting severe chatter. I pull the clutch back in a tad and let it out and it seems to grab better and the wheel comes up. Happens every single time. I dont mind the wheel coming up, that issue can be addressed but the chatter issue is a problem. It either bogs, chatters, or wheel comes right up at the launch. There is no in between to float the clutch like I could do on other bikes and carry the front wheel from the launch until it settles.
Obviously we are talking about drag racing here. Stock clutch has about 4k miles on it. 07 ZX10R. Best I can pull is a 1.9 60' I have video of my launches to show you what I mean. You cn hear me launch the bike, I can feel it chattering then I slip the clutch back in a little and it slips and grabs nice.
If it matters, I am using a mobil1 syn 10-30 oil.
