My engine is internally balanced. I feel a vibration after 3000 RPM. After I changed my first clutch Spec 3, I simply replaced with a Spec 3+. Do these clutches came balanced? Could that be the reason of vibration?? If so when I take out the clutch, it vibration will be dissapear? Or could my engine messed up ?

Hope you understand my english

did you remove the flywheel?,if so did it you mark its location to the crankshaft so you could make sure it went back on the same way?

No I didn't remove the flywheel. I just get a new friction plate and replace it. I only swap the clutch. This makes sense? Or do I have a vibration issue related to another thing ? Misfire ?
