The new clutch assembly does not come with lube which is specified by Yamaha, molybdenum-disulphide oil.
I used 50/50 mix of STP and engine oil instead, and it has been trouble free.
Three rollers on clutch assembly should retract due to centrifugal force as the engine starts and run, dis-engaging clutch. Since you have new assembly it is hard to have wrong spring used to prevent rollers to retract.
If your starter motor continued to get voltage as my starter motor has had, you will hear faint mechanical sound. My engine continued to operate normally. It did not hinder idling.
Your idling issue may not be related to starter issue.
The lock nut torque for primary sheave is 40 ft-lb.
