clutch adjustment on 2005 C50

I put 14" apes on my C50. I of course had to ghange all the cables. The aftermarket braided clutch cable from Barnett only has an aduster on the engine end and not at the lever. there is too much slop in the clutch lever and if I twist the throttle hard in higher gears the clutch is slipping. Any body got any ideas. there aint enough screw to adjust.
