Floppy kickstart

Hello. My scoot is an absolute nightmare to start from cold. She'll bump ok (ish) but kicking over is no good. The kickstart mechanism seems 'floppy' to me. I did change the crankcase cover during my rebuild and had to fit a 'bespoke' kickstart lever to clear the Ancillotti. So I couldn't really set the mechanism as I removed and replaced the original lever. Can someone tell me how to set the kick start from scratch so I can get a bit of purchase when I kick her over. She starts ok when warm. Thanks
