So, I've heard alot about this infamous 2nd gear issue, I don't seem to have that on my bike, by struggle is getting into 3-5, the shifter won't budge past second, first,neutral 2nd all work, but it won't go further , i tried adjusting the shift , but after doing that I just ended up putting so much force into I bent the adjustment screw, any advice on what I should do or where to get a new screw?
