YFM225 revs a little before auto clutch engages

[lynitup82]

Its a 86 yfm 225 (early version of the big bear) automatic clutch. I revs just a little before engagement then grabs hard. Its still perfectly rideable, and i have adjusted the screw and locknut per the manuals specs. It just dosnt have that instant movement-response when the gas is hit in gear from a stop or rolling/shifting
Otherwise, it has no slippage, pushed snow all winter with no problems.
It goes into gear very solid when goiing from rev or frwd

Thanks
