Installed a sachs performance sintered clutch a few months back as the standard clutch was slipping after a stage 1 remap. Ive done about 700 miles since fitted, and the last couple weeks a noise has started when Im pulling off, and when I changed down a gear. It happens when Im on the bite point. The most common noise is high pitched like a whistle, but on the odd occasion when pulling off, theres a scraping noise and I feel some vibration in the clutch pedal.
Just wondering if anyone knows why its doing this, or if its part and parcel with a sintered clutch.
Cheers
