clutch chatter

hi, i have an 08 700 grizz. that the clutch brake does not stay engaged all the time. it sometimes cuts out at lower rpm’s, and sounds like a grinding noise. i have it apart now[adjusted the valves], and would like to address this problem. also,i read a while ago, i read some thing about cutting a wire, and entering the comp. to [grounding a wire, i think] to get the thing to run better. ant info would be greatly appreciated. thanks.
