Duster Shakes on take off

O.K. first I ask if it was a sintered disk and said nothing about iron!
Sintered meaning material such as copper, iron, steel, ceramic compressed into a shape, And this is not helping the OP question. Is the flywheel iron or steel, has it been surfaced, and yes if the disk has oil on it there is realy no good way to get it out. Good luck 76duster.



Post 8 says you ran a sintered disc. If the disc you ran is like the one in the picture that is NOT a sintered disc. You are confusing **** by calling something something that it's not.

So did you actually use a sintered disc on the street or did you use what used to be called a "velvet touch" disc like the one pictured?
