so I got my hands on a workhorse..(I just had to) I herd so much that was wrong with the machine so I had to see if I could make it work.. I feel the only flaw in the design is the crank arm and bearing in the rear. so I put a crank arm off of a stealth on the machine and used a rubber grommet and all the noise is gone now.. the arm can stand to be a hair shorter but it works..here is a pic..maybe bill can go back and redesign the rear crank and he will have a great machine.Attachment 9357the only other thing that makes noise is the pivot point for the arm bar and I will soon find a fix for it..maybe if the end was rubber coated. but it is so small of a noise it doesn't matter
