Anybody else have trouble with the tip on your Hammerhead shifter not fully extending back to its normal position? I had to replace the spring last month at the track for that reason. I only race/ride once a month and this month in practice the shifter stayed folded up and I couldnt shift very easy. I had my spare stock one and had to change it. Now I have the faulty shifter and no spring and I am wondering if I change the spring again will I run into the same problem.
