Those who have replaced their cush drive springs with aftermarket kit from Mikes, how did it work out? I have to do mine, one broke and one too loose. This summer, in certain situations, my bike felt like it had an elastic drive train on take off, very weird feeling when in traffic. Everything checked ok, no broken or loose bolts or pivots. Now that the winter is here, decided to check the drive springs, and found the problem. Several guys have done the job, seems fairly straight forward, but no info on if it was successful.
