My bike shifts fine from neutral up to second and up to thru fifth gear and back down to neutral. However, it wont go past neutral into first unless I work it on the stand. First thing I'm thinking, I should check is the shift pawl ratchet and the shift shaft. Hopefully that's it. Has anyone seen a similar issue with and without a hardened shifter? I have a Hammerhead shift lever and I wonder if that wasn't a good idea to install it as all the energy from a hit to the shifter would be transferred to the shift shaft where a stock shifter would be more malleable and bend or break off.
