Squeaky clutch lever

[freddy871]

I have a loud squeak when pullin in clutch lever , finding it hard to pin point. Bike has bar busters so thought it could be replacement bolt. WD 40 grease no change. So now think it's master cylinder ping rubber. Any one else had this and  have a cure ??;

Try some teflon spray inside the rubber protection sleeve.
