    Eagle Mfg. Doohickey Torsion Spring

    Michael in CA

    The torsion spring upgrade is pretty much what Kawasaki should have done from the start. Simple, straightforward, reliable. It does require drilling of the generator case cover to install. Just remember that most videos about installing the torsion spring may not cover the newest version of this part, so if there are any questions always refer to the EM instructions.
