Px200/ malossi 210 clutch probs

have been having problem with my clutch on my px210 malossi fitted with a hp4 flywheel, 30mm phbh reed valve malossi kit. Took out old style 7 spring clutch and fitted 23t 4 plate cosa clutch new stonger springs, new corks and plates, after fitting it the clutch is not right it does not biite intill clutch lever is nearly fully out, it seems to be very snappy, were as when using  clutch has to be used carefully not like it should.  So going out to ride it is not a good ride as the clutch acting as it does i find at juctions etc i use more reves to pull away due to it engageing so late.  Any ideas as to what might be wrong, have I missed somthing, should i go back to the older 7 spring clutch or is there any ideas anybody has on clutchs.   I did have the scooter dyno tunned a few mths back and was at 20bhp.  Hope my writing is ok and not to hard to understand find it hard to exsplain things out. hope somebody can help as i have scooter sitting around and not getting to enjoy it....
