Anybody heard of these, they are primary washers that are coated and prevent the primary spring from binding, for $14.95 you get two coated washers and 3 non coated, they say each adds 40-50 rpm. Are the Yamaha primary prone to this problems...........James

I got them and they work for fine tuning the engagement rpm and they seem to, but I can not prove it, help keep the primary from binding up.
