OK. I have a 2000 GSR and 7 months ago I installed a Clutchmasters stage 3 clutch and a Clutchmasters lightweight flywheel. About a week ago this started. Everytime I take off in first, there is a shudder that comes when I release the clutch. The slower I release the clutch the worse it gets. The clutch itself doesn't seem to be slipping. one guy told me it is because it is a racing clutch and it is grabbing to much and it is normal. Another guy told me I probably had stress fractures in my flywheel and that was the cause. Anyone know what this is?
