Hey all, long time no see. I've been trying to keep tinkering with my motors in the hopes of becoming better. Lately my motor has been making a loud whirring (whining?) noise when I release the clutch. Is this a sign of having to replace the clutch pads? It's really loud, I can hear it over the motor... (Only sounds when the clutch is released, not held) Also, I bought a clutch puller to check out the clutch disk on a different motor. How does one go about using that tool? And my final question is, instead of buying a super expensive cylinder head to get better compression, is it possible to add an extra head gasket to add more space between the piston and head? Or is that the exact opposite of adding compression?
